It combines a <strong>2.6 GHz six-core Intel Core i5-11500HE processor<\/strong>, dual-channel DDR4 memory, NVMe solid-state storage and a maximum controller bandwidth of <strong>8 GB\/s<\/strong>.<\/p>\n<p>The controller is well suited for multifunction data acquisition, production testing, validation laboratories and applications requiring moderate data streaming. Because the computing system is installed directly in the PXI Express chassis, the PXIe-8842 creates a compact, self-contained platform without requiring an external desktop computer or remote-control interface.<\/p>\n<p>Available interfaces include two 2.5 Gigabit Ethernet ports, Thunderbolt 4, DisplayPort 1.4, USB 3.2 Gen 1, USB 2.0, RS-232 serial and an SMB trigger connector. Separate ordering configurations are available with or without a GPIB port and with Windows, NI Linux Real-Time or no preinstalled operating system.<\/p>\n<h3>Key Features of the PXIe-8842<\/h3>\n<ul>\n<li>2.6 GHz Intel Core i5-11500HE processor<\/li>\n<li>Six processor cores for parallel test execution<\/li>\n<li>12 MB Intel Smart Cache<\/li>\n<li>16 GB standard dual-channel DDR4-3200 memory<\/li>\n<li>32 GB maximum supported memory<\/li>\n<li>512 GB or greater M.2 NVMe solid-state drive<\/li>\n<li>8 GB\/s maximum PXI Express controller bandwidth<\/li>\n<li>5.0 GT\/s PCI Express link speed<\/li>\n<li>Two 10\/100\/1000\/2500BASE-T Ethernet ports<\/li>\n<li>IEEE 1588-capable Intel I225 Ethernet interfaces<\/li>\n<li>One Thunderbolt 4 USB Type-C port<\/li>\n<li>Two USB 3.2 Gen 1 Type-A ports<\/li>\n<li>Four USB 2.0 Type-A ports<\/li>\n<li>One DisplayPort 1.4 video output<\/li>\n<li>One DB-9 RS-232 serial port<\/li>\n<li>Optional mini-GPIB interface<\/li>\n<li>SMB connector for PXI trigger-bus routing<\/li>\n<li>Windows 10, Windows 11 and NI Linux Real-Time configurations<\/li>\n<li>Optional TPM 2.0 hardware security<\/li>\n<li>0\u00b0C to 55\u00b0C operating-temperature range<\/li>\n<\/ul>\n<h3>Six-Core Intel Core i5 Processing<\/h3>\n<p>The PXIe-8842 uses an Intel Core i5-11500HE processor with six physical cores and 12 MB of Smart Cache. Its multicore architecture allows test applications to divide instrument control, data acquisition, result processing, logging and user-interface tasks across multiple processor cores.<\/p>\n<p>This processing capability is valuable in automated systems that operate several PXI instruments simultaneously. For example, one test sequence can acquire waveforms while another software process analyzes earlier records, stores results or communicates with factory systems.<\/p>\n<p>Intel Turbo Boost can temporarily operate processor cores above the base frequency when workload and thermal conditions permit. In deterministic real-time applications, engineers should evaluate the effect of Turbo Boost and processor power-management settings on execution jitter before changing the default BIOS configuration.<\/p>\n<h3>16 GB Dual-Channel DDR4 Memory<\/h3>\n<p>The standard PXIe-8842 memory configuration consists of two 8 GB DDR4-3200 non-ECC SODIMMs, providing a total of <strong>16 GB<\/strong> in dual-channel mode. The controller supports as much as 32 GB using two compatible 16 GB modules.<\/p>\n<p>Dual-channel memory provides greater memory bandwidth than a comparable single-channel configuration. This can benefit test applications that perform waveform processing, data conversion, database operations or simultaneous control of multiple instruments.<\/p>\n<p>Memory capacity should be selected according to the operating system, application framework, number of instruments, waveform size and expected data-processing workload. Use compatible memory configurations and follow the controller service instructions when replacing or upgrading SODIMMs.<\/p>\n<h3>NVMe Solid-State Storage<\/h3>\n<p>The controller includes a <strong>512 GB or greater M.2 NVMe solid-state drive<\/strong>. NVMe storage provides fast startup, application loading and test-data access while eliminating the moving components associated with mechanical hard drives.<\/p>\n<p>The drive is internally installed and is not a front-removable storage device. NI identifies a compatible 512 GB, 80 mm M.2 NVMe SSD under part number <strong>788897-01<\/strong> for supported controller service applications.<\/p>\n<p>Storage requirements should account for the operating system, instrument drivers, development software, recovery files and accumulated test data. High-volume waveform or production data should be archived regularly to network or external storage instead of allowing the system drive to become full.<\/p>\n<h3>8 GB\/s PXI Express Bandwidth<\/h3>\n<p>The PXIe-8842 provides up to <strong>8 GB\/s maximum controller-to-backplane bandwidth<\/strong>. This capability supports multifunction DAQ and test applications that require moderate streaming between the embedded controller and installed PXI Express instruments.<\/p>\n<p>The controller supports a four-link configuration of x4, x4, x4 and x4, or a two-link configuration of x8 and x8, depending on the chassis backplane architecture. Its PCI Express link speed is 5.0 GT\/s.<\/p>\n<p>Actual data throughput depends on the chassis, slot configuration, installed modules, driver architecture, memory transfers, storage activity and test software. The maximum controller bandwidth does not guarantee that every peripheral module or storage operation can sustain the same rate.<\/p>\n<h3>Dual 2.5 Gigabit Ethernet<\/h3>\n<p>Two Intel I225 Ethernet interfaces provide 10 Mbps, 100 Mbps, 1 Gbps and 2.5 Gbps network operation through standard RJ45 connectors. The two independent ports can be assigned to separate instrument, enterprise, DUT or control networks.<\/p>\n<p>Dual Ethernet connections are useful when production traffic must be separated from instrument communication. One interface can communicate with networked devices under test while the second transfers results to a server or connects the controller to a facility network.<\/p>\n<p>The Ethernet interfaces support Wake-on-LAN and IEEE 1588 functionality. IEEE 1588 can assist with time coordination in compatible network architectures, although the timing accuracy of the complete system depends on the network equipment, software and synchronization design.<\/p>\n<h3>Thunderbolt 4 Connectivity<\/h3>\n<p>The PXIe-8842 provides one Thunderbolt 4 port through a USB Type-C connector. The interface supports compatible Thunderbolt, USB, PCI Express and DisplayPort functions.<\/p>\n<p>Thunderbolt 4 expands the controller\u2019s connectivity for supported displays, storage devices and other peripherals. Compatibility should be verified for the specific device, cable, operating system and driver combination before deployment.<\/p>\n<p>Power delivered to external equipment through the Thunderbolt port must be included in the total chassis power calculation. The presence of a USB Type-C connector alone does not guarantee compatibility with every Type-C accessory or alternate operating mode.<\/p>\n<h3>USB Peripheral Connections<\/h3>\n<p>The controller provides two USB 3.2 Gen 1 Type-A ports for SuperSpeed peripherals and four USB 2.0 Type-A ports for keyboards, mice, license devices and other lower-bandwidth accessories.<\/p>\n<p>USB 3.2 Gen 1 ports are backward compatible with USB 2.0 equipment. High-throughput devices such as external drives should normally be connected to the faster ports, leaving the USB 2.0 interfaces available for human-interface and configuration devices.<\/p>\n<p>External USB loads consume chassis power and may affect the system power budget. For permanent installations, secure cables and avoid connecting bus-powered devices that exceed the supported port or chassis capacity.<\/p>\n<h3>DisplayPort 1.4 Video Output<\/h3>\n<p>One DisplayPort 1.4 connector provides video output through the processor\u2019s integrated Intel graphics. A monitor can be used for controller setup, BIOS configuration, software development and local operation of the test system.<\/p>\n<p>NI includes a 7-inch DisplayPort-to-VGA adapter cable with the controller. When a modern digital monitor is available, a direct DisplayPort connection can avoid the analog conversion required by VGA.<\/p>\n<h3>RS-232 and Optional GPIB Interfaces<\/h3>\n<p>A DB-9 RS-232 port supports communication with serial instruments, programmable devices, legacy test fixtures and industrial equipment. Application software can access compatible serial devices through the appropriate operating-system and NI-VISA resources.<\/p>\n<p>Selected PXIe-8842 versions also include a 25-pin Micro-D mini-GPIB interface supporting IEEE 488.2 instrument communication. No-GPIB versions are available for systems that do not require legacy parallel instrument control.<\/p>\n<p>The GPIB configuration must be selected when ordering because the port is not present on no-GPIB variants. A compatible mini-GPIB cable or adapter is required when connecting conventional GPIB instruments.<\/p>\n<h3>PXI Trigger Bus Connection<\/h3>\n<p>The front-panel SMB connector can route PXI trigger signals to or from the chassis backplane trigger bus. This provides a convenient way to coordinate external equipment with PXI instruments and system events.<\/p>\n<p>Trigger direction, line assignment and electrical compatibility must be configured for the application. The trigger connector is intended for synchronization and control signals rather than general-purpose analog measurements.<\/p>\n<h3>Operating System Options<\/h3>\n<p>The PXIe-8842 is available with Windows 11 IoT Enterprise LTSC, Windows 10 IoT Enterprise LTSC, NI Linux Real-Time or no operating system. The correct version depends on software compatibility, deterministic execution requirements, security policy and expected lifecycle.<\/p>\n<h4>Windows Configurations<\/h4>\n<p>Windows configurations are appropriate for systems using desktop applications, LabVIEW, TestStand, InstrumentStudio and third-party Windows software. Confirm that all required PXI instrument drivers support the selected Windows version before ordering.<\/p>\n<h4>NI Linux Real-Time Configurations<\/h4>\n<p>NI Linux Real-Time configurations are intended for deterministic test, control and hardware-in-the-loop applications. Real-time compatibility must be checked for every installed module, driver and software component.<\/p>\n<h4>No-OS Configuration<\/h4>\n<p>The no-operating-system version allows a qualified system integrator to apply an independently managed software image. Operating-system installation, activation, driver support and recovery planning become the responsibility of the system owner.<\/p>\n<h3>TPM 2.0 Security Options<\/h3>\n<p>Selected Windows and no-OS variants include a Trusted Platform Module 2.0. TPM hardware can support operating-system security functions such as device identity, secure key storage and drive-encryption workflows.<\/p>\n<p>The NI Linux Real-Time ordering configurations listed for this controller do not include TPM. Security features depend on the selected operating system, BIOS settings and organization-level configuration; the presence of TPM hardware does not enable every security feature automatically.<\/p>\n<h2>PXIe-8842 Technical Specifications<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Product Model<\/th>\n<td>PXIe-8842<\/td>\n<\/tr>\n<tr>\n<th>Product Type<\/th>\n<td>PXI Express embedded controller<\/td>\n<\/tr>\n<tr>\n<th>\u041f\u0440\u043e\u0446\u0435\u0441\u0441\u043e\u0440<\/th>\n<td>Intel Core i5-11500HE<\/td>\n<\/tr>\n<tr>\n<th>Base Processor Frequency<\/th>\n<td>2.6 GHz<\/td>\n<\/tr>\n<tr>\n<th>Processor Cores<\/th>\n<td>6<\/td>\n<\/tr>\n<tr>\n<th>Processor Cache<\/th>\n<td>12 MB Smart Cache<\/td>\n<\/tr>\n<tr>\n<th>Standard Memory<\/th>\n<td>16 GB total, 2 \u00d7 8 GB<\/td>\n<\/tr>\n<tr>\n<th>Maximum Memory<\/th>\n<td>32 GB total, 2 \u00d7 16 GB<\/td>\n<\/tr>\n<tr>\n<th>Memory Type<\/th>\n<td>Dual-channel DDR4-3200 non-ECC SODIMM<\/td>\n<\/tr>\n<tr>\n<th>\u0425\u0440\u0430\u043d\u0435\u043d\u0438\u0435<\/th>\n<td>512 GB or greater M.2 NVMe SSD<\/td>\n<\/tr>\n<tr>\n<th>Removable Drive<\/th>\n<td>No<\/td>\n<\/tr>\n<tr>\n<th>Maximum Controller Bandwidth<\/th>\n<td>8 GB\/s<\/td>\n<\/tr>\n<tr>\n<th>PCI Express Link Speed<\/th>\n<td>5.0 GT\/s<\/td>\n<\/tr>\n<tr>\n<th>Four-Link Configuration<\/th>\n<td>x4, x4, x4, x4<\/td>\n<\/tr>\n<tr>\n<th>Two-Link Configuration<\/th>\n<td>x8, x8<\/td>\n<\/tr>\n<tr>\n<th>Ethernet<\/th>\n<td>2 \u00d7 10\/100\/1000\/2500BASE-T RJ45 ports<\/td>\n<\/tr>\n<tr>\n<th>Ethernet Controllers<\/th>\n<td>Intel I225 with Wake-on-LAN and IEEE 1588 support<\/td>\n<\/tr>\n<tr>\n<th>Thunderbolt<\/th>\n<td>1 \u00d7 Thunderbolt 4 USB Type-C port<\/td>\n<\/tr>\n<tr>\n<th>USB 3.2 Gen 1<\/th>\n<td>2 \u00d7 Type-A ports<\/td>\n<\/tr>\n<tr>\n<th>USB 2.0<\/th>\n<td>4 \u00d7 Type-A ports<\/td>\n<\/tr>\n<tr>\n<th>Video Output<\/th>\n<td>1 \u00d7 DisplayPort 1.4<\/td>\n<\/tr>\n<tr>\n<th>Serial Interface<\/th>\n<td>1 \u00d7 DB-9 RS-232 port<\/td>\n<\/tr>\n<tr>\n<th>GPIB Interface<\/th>\n<td>Optional 25-pin Micro-D mini-GPIB port, IEEE 488.2<\/td>\n<\/tr>\n<tr>\n<th>Trigger Interface<\/th>\n<td>1 \u00d7 SMB PXI trigger-bus input\/output<\/td>\n<\/tr>\n<tr>\n<th>Operating System Options<\/th>\n<td>Windows 11 IoT, Windows 10 IoT, NI Linux Real-Time or no OS<\/td>\n<\/tr>\n<tr>\n<th>Security Hardware<\/th>\n<td>Optional TPM 2.0, configuration dependent<\/td>\n<\/tr>\n<tr>\n<th>Module Size<\/th>\n<td>Four-wide 3U PXI Express module<\/td>\n<\/tr>\n<tr>\n<th>Slot Requirement<\/th>\n<td>One system slot plus three controller expansion slots<\/td>\n<\/tr>\n<tr>\n<th>Typical Weight<\/th>\n<td>753 g<\/td>\n<\/tr>\n<tr>\n<th>Operating Temperature<\/th>\n<td>0\u00b0C to 55\u00b0C<\/td>\n<\/tr>\n<tr>\n<th>Operating Humidity<\/th>\n<td>10% to 90%, noncondensing<\/td>\n<\/tr>\n<tr>\n<th>Storage Temperature<\/th>\n<td>-40\u00b0C to 71\u00b0C<\/td>\n<\/tr>\n<tr>\n<th>Storage Humidity<\/th>\n<td>5% to 95%, noncondensing<\/td>\n<\/tr>\n<tr>\n<th>Maximum Altitude<\/th>\n<td>4,600 m at 25\u00b0C with chassis fans set to high<\/td>\n<\/tr>\n<tr>\n<th>Operating Shock<\/th>\n<td>30 g peak, half-sine, 11 ms pulse<\/td>\n<\/tr>\n<tr>\n<th>Operating Random Vibration<\/th>\n<td>5 Hz to 500 Hz, 0.3 grms<\/td>\n<\/tr>\n<tr>\n<th>Nonoperating Random Vibration<\/th>\n<td>5 Hz to 500 Hz, 2.4 grms<\/td>\n<\/tr>\n<tr>\n<th>\u0421\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0441\u0442\u044c \u0441 PXI<\/th>\n<td>PXI Express Specification 1.0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXIe-8842 Electrical Requirements<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Power Rail<\/th>\n<th>Typical Current<\/th>\n<th>\u041c\u0430\u043a\u0441\u0438\u043c\u0430\u043b\u044c\u043d\u044b\u0439 \u0442\u043e\u043a<\/th>\n<\/tr>\n<tr>\n<td>+3.3 V<\/td>\n<td>1.2 A<\/td>\n<td>2.6 A<\/td>\n<\/tr>\n<tr>\n<td>+5 V<\/td>\n<td>0.9 A<\/td>\n<td>3.0 A<\/td>\n<\/tr>\n<tr>\n<td>+12 V<\/td>\n<td>5.1 A<\/td>\n<td>7.1 A<\/td>\n<\/tr>\n<tr>\n<td>+5 V auxiliary<\/td>\n<td>0.4 A<\/td>\n<td>0.7 A<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The controller\u2019s electrical specifications do not include attached USB or Thunderbolt devices.

Select NI Linux Real-Time when deterministic execution and supported real-time drivers are central requirements.<\/p>\n<p>Choose a GPIB-equipped version when the system must control IEEE 488 instruments. A no-GPIB model can be selected when all instruments use PXI, USB, Ethernet, serial or other interfaces. For security-managed Windows installations, confirm that the selected part number includes TPM 2.0.<\/p>\n<h2>PXIe-8842 Applications<\/h2>\n<h3>Automated Test Equipment<\/h3>\n<p>The PXIe-8842 can serve as the central computer in automated test equipment containing digitizers, digital multimeters, waveform generators, programmable power instruments, switch modules and data-acquisition hardware.<\/p>\n<p>Its six processor cores help separate instrument control, test sequencing, analysis and reporting workloads. The integrated architecture also reduces the number of external computers and interface cables required in a rack-mounted system.<\/p>\n<h3>Multifunction Data Acquisition<\/h3>\n<p>The controller supports PXI Express multifunction DAQ systems that acquire analog, digital and counter signals. Its 8 GB\/s backplane interface provides room for moderate streaming workloads across compatible modules.<\/p>\n<p>Required throughput should be calculated from the number of channels, sample rates, sample width, number of modules and acquisition duration. Processing and storage performance must also be considered when data is streamed continuously.<\/p>\n<h3>Production Functional Testing<\/h3>\n<p>Production systems can use the PXIe-8842 to execute test sequences, configure instruments, analyze results and communicate with factory databases. Dual Ethernet ports can separate DUT communication from enterprise or manufacturing-network traffic.<\/p>\n<p>The controller can be combined with TestStand for sequence execution and result handling, while LabVIEW or supported text-based software provides instrument control and custom measurements.<\/p>\n<h3>Design Validation and Verification<\/h3>\n<p>Validation laboratories can use the PXIe-8842 for automated characterization of electronic assemblies and subsystems. Multiple instruments can be synchronized, configured and read from a single embedded computing platform.<\/p>\n<p>Its front-panel trigger connector, Ethernet ports and legacy interfaces help integrate PXI hardware with external laboratory equipment and custom fixtures.<\/p>\n<h3>Hardware-in-the-Loop and Real-Time Control<\/h3>\n<p>An NI Linux Real-Time version can be used for supported deterministic test and control applications. Typical examples include controller validation, closed-loop simulation and synchronized fault-response testing.<\/p>\n<p>Real-time suitability depends on the complete system. Confirm module-driver support, loop rates, CPU utilization, interrupt behavior and timing architecture before selecting the controller for a critical HIL application.<\/p>\n<h3>RF and Wireless Test Systems<\/h3>\n<p>The PXIe-8842 can control compatible PXI RF signal generators, analyzers, transceivers and switches. Its multicore processor can coordinate measurement stages and perform moderate signal-processing workloads.<\/p>\n<p>High-bandwidth RF applications may require more processor performance, memory or backplane bandwidth than the PXIe-8842 provides. Calculate the expected waveform rate and analysis workload before choosing between the PXIe-8842 and a higher-performance controller.<\/p>\n<h3>Laboratory Automation<\/h3>\n<p>The optional GPIB port, RS-232 interface, USB connections and Ethernet ports make the controller useful for laboratories that combine modern PXI instruments with existing standalone equipment.<\/p>\n<p>Software-defined communication can replace manual setup and allow repeatable measurements across multiple instruments, environmental chambers, power supplies and devices under test.<\/p>\n<h2>PXIe-8842 Installation Workflow<\/h2>\n<h3>Step 1: Verify the Ordered Configuration<\/h3>\n<p>Check the controller part number against the required operating system, GPIB port and TPM configuration. Confirm that the selected operating system supports the planned applications and instrument drivers.<\/p>\n<h3>Step 2: Confirm Chassis Compatibility<\/h3>\n<p>Use a compatible PXI Express chassis with an available system-controller slot and three adjacent controller expansion slots. The PXIe-8842 is a four-wide module and cannot be installed where the required adjacent space is occupied.<\/p>\n<h3>Step 3: Review Cooling and Power Capacity<\/h3>\n<p>Confirm that the chassis can supply the controller and all installed modules. Include USB and Thunderbolt peripherals in the power calculation. Maintain clear airflow and use the required chassis fan setting for the ambient temperature and altitude.<\/p>\n<h3>Step 4: Apply ESD Protection<\/h3>\n<p>Keep the controller in its antistatic packaging until installation. Ground yourself with an approved wrist strap or touch a grounded chassis surface before handling the module. Do not touch exposed connector pins.<\/p>\n<h3>Step 5: Power Off the Chassis<\/h3>\n<p>Connect the chassis power cord to establish protective grounding, but keep the chassis powered off during installation. Follow the chassis-specific instructions because power-switch and inhibit behavior can vary between models.<\/p>\n<h3>Step 6: Install the Controller<\/h3>\n<p>Lower the injector\/ejector handle, align the controller with the system-slot guides and insert it without forcing the connectors. Seat the module using the handle and secure the four front-panel retaining screws.<\/p>\n<h3>Step 7: Connect Basic Peripherals<\/h3>\n<p>Connect a DisplayPort monitor, keyboard and mouse when local setup is required. Attach Ethernet, serial, GPIB, USB, Thunderbolt and trigger cables only after verifying their pinout and compatibility.<\/p>\n<h3>Step 8: Start the Controller<\/h3>\n<p>Power on the chassis and allow the controller to complete its startup sequence. Enter the BIOS only when boot order, power-restoration behavior, security or other platform settings must be changed.<\/p>\n<h3>Step 9: Install Software and Drivers<\/h3>\n<p>Install or verify the operating system, NI Platform Services and drivers for every installed PXI module. For real-time systems, use software versions supported by the selected NI Linux Real-Time release.<\/p>\n<h3>Step 10: Verify the Complete PXI System<\/h3>\n<p>Confirm that the controller, chassis and peripheral modules are detected correctly. Test the Ethernet, serial, GPIB and trigger interfaces required by the application before deploying the final test sequence.<\/p>\n<h3>Step 11: Create a Recovery Plan<\/h3>\n<p>Record BIOS settings, application versions, driver revisions, network configuration and license information. Retain the supplied recovery media and create a validated backup before the controller enters production service.<\/p>\n<h2>PXIe-8842 Troubleshooting<\/h2>\n<h3>The PXIe-8842 Does Not Power On<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Verify chassis input power, power-switch position and inhibit settings. Confirm that the controller is fully seated in the system slot and that its front-panel screws are secured. Remove unsupported external USB or Thunderbolt loads when diagnosing a possible power-capacity problem.<\/p>\n<h3>The Controller Is Not Detected Correctly<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Power off the chassis and reseat the controller using proper ESD precautions. Confirm that it is installed in the designated system-controller slot rather than a peripheral slot. Review chassis compatibility and inspect the backplane connectors for contamination or damage.<\/p>\n<h3>PXI Peripheral Modules Are Missing<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Verify that the required drivers are installed and compatible with the operating system. Check module seating and chassis slot compatibility. If a link fails after startup in an older chassis using Gen 1 or Gen 2 PCI Express switches, power-cycle the complete system as described in the NI controller documentation.<\/p>\n<h3>The System Does Not Boot from the NVMe Drive<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Review the BIOS boot order and confirm that the M.2 NVMe SSD is detected. Remove unnecessary bootable USB storage and inspect the drive only after powering down and removing the controller according to the service procedure.<\/p>\n<h3>Ethernet Operates Below 2.5 Gbps<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Confirm that the network adapter, switch port and cable all support 2.5GbE. Check link negotiation, operating-system drivers and switch configuration. Actual file-transfer speed can be lower than the nominal Ethernet link rate because of protocol, storage and processing overhead.<\/p>\n<h3>The Thunderbolt Device Is Not Recognized<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Use a certified cable and confirm that the peripheral, operating system and installed driver support the required Thunderbolt mode. Check device power requirements and test the peripheral without intermediate adapters or docks.<\/p>\n<h3>A GPIB Instrument Cannot Be Found<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>First confirm that the ordered controller actually includes the mini-GPIB port. Inspect the cable and instrument address, install the required NI-488.2 software and verify that no two devices on the bus use the same primary address.<\/p>\n<h3>The Controller Runs Too Hot<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Check chassis airflow, fan mode, ambient temperature and adjacent module loading. Clean or replace chassis air filters according to the chassis maintenance schedule. The PXIe-8842 operating temperature must not exceed 55\u00b0C even if the chassis has a higher published temperature limit.<\/p>\n<h3>Real-Time Execution Shows Excessive Jitter<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Measure CPU usage and review task priorities, network traffic and background processes. Evaluate Turbo Boost, C-state and power-management settings carefully. Higher peak processor frequency can increase timing variation in some real-time workloads.<\/p>\n<h3>The Controller Does Not Restart After a Power Failure<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Review the BIOS Restore After Power Loss setting. The default is Stay Off; select Turn On only when automatic restart is required and permitted by the test-system safety design.<\/p>\n<h3>The System Drive Is Nearly Full<\/h3>\n<h5>Recommended Checks<\/h5>\n<p>Archive test results and large waveforms to approved network or external storage. Remove obsolete installer files only after confirming they are no longer required. Maintain a validated recovery image before replacing or reformatting the NVMe drive.<\/p>\n<h2>PXIe-8842 Comparison<\/h2>\n<table>\n<tbody>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>Processor Class<\/th>\n<th>Key Positioning<\/th>\n<th>Best Suited For<\/th>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8822\/\">PXIe-8822<\/a><\/td>\n<td>Intel Core i3, four cores<\/td>\n<td>Entry-level controller in the same generation<\/td>\n<td>General instrument control and lighter automated tests<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8842\/\">PXIe-8842<\/a><\/td>\n<td>Intel Core i5, six cores<\/td>\n<td>16 GB standard memory and 8 GB\/s controller bandwidth<\/td>\n<td>Multifunction DAQ and moderate-streaming test systems<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8862\/\">PXIe-8862<\/a><\/td>\n<td>Intel Core i7, eight cores<\/td>\n<td>More processing, memory and peripheral capability<\/td>\n<td>Heavier analysis and more demanding automated tests<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8840\/\">PXIe-8840<\/a><\/td>\n<td>Earlier-generation Intel Core i5<\/td>\n<td>Established controller for existing systems<\/td>\n<td>Maintaining compatible legacy PXI Express installations<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8880\/\">PXIe-8880<\/a><\/td>\n<td>High-performance Intel Xeon class<\/td>\n<td>Greater compute capability for demanding workloads<\/td>\n<td>Processor-intensive RF, analysis and test applications<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXIe-8842 vs PXIe-8822<\/h3>\n<p>The PXIe-8842 provides a six-core Intel Core i5 processor, while the PXIe-8822 uses a four-core Intel Core i3 processor. The PXIe-8842 also provides dual-channel memory, dual Ethernet, Thunderbolt 4 and higher PCI Express link performance.<\/p>\n<p>Select the PXIe-8822 for lighter instrument-control applications where acquisition and analysis demands are limited. Choose the PXIe-8842 when additional processor cores, networking and backplane throughput provide useful system margin.<\/p>\n<h3>PXIe-8842 vs PXIe-8862<\/h3>\n<p>The PXIe-8862 is the higher-performance member of the same controller family. It uses an eight-core Intel Core i7 processor, supports more memory and provides additional high-performance connectivity.<\/p>\n<p>The PXIe-8842 offers a balanced configuration for multifunction DAQ and moderate streaming. The PXIe-8862 is better suited when the application performs heavier parallel analysis, handles larger datasets or requires more expansion capacity.<\/p>\n<h3>PXIe-8842 vs PXIe-8840<\/h3>\n<p>The PXIe-8840 is an earlier embedded-controller generation commonly found in established PXI systems. The PXIe-8842 provides a newer six-core processor platform, 2.5GbE networking, Thunderbolt 4 and current operating-system configurations.<\/p>\n<p>When replacing an existing PXIe-8840, verify chassis compatibility, software versions, operating-system requirements, connector differences and application licensing before migration.<\/p>\n<h3>Embedded Controller vs Remote PXI Control<\/h3>\n<p>An embedded controller such as the PXIe-8842 creates a self-contained chassis with no separate host computer. A remote-control architecture connects the PXI chassis to an external workstation using an interface such as MXI-Express or Thunderbolt.<\/p>\n<p>Embedded control simplifies cabling and makes the system easier to deploy as one integrated unit. Remote control may be preferable when the application requires a specialized workstation, centralized computing or easier independent computer upgrades.<\/p>\n<h3>Recommended Related Products<\/h3>\n<ul>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8822\/\">PXIe-8822 PXI Express Embedded Controller<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8862\/\">PXIe-8862 High-Performance PXI Express Controller<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8840\/\">PXIe-8840 PXI Express Embedded Controller<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8880\/\">PXIe-8880 PXI Express Embedded Controller<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-8881\/\">PXIe-8881 PXI Express Embedded Controller<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/%d0%bf%d1%8c%d0%b5-1095\/\">PXIe-1095 PXI Express Chassis<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-1092\/\">PXIe-1092 PXI Express Chassis<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product-category\/%d0%bd%d0%b8\/pxi-%d1%81%d0%b8%d1%81%d1%82%d0%b5%d0%bc%d1%81\/pxi-controller\/\">View More NI PXI Controllers<\/a><\/li>\n<\/ul>\n<h3>Why Choose the PXIe-8842?<\/h3>\n<ul>\n<li>Balanced six-core processing for automated test applications<\/li>\n<li>Up to 8 GB\/s controller-to-backplane bandwidth<\/li>\n<li>16 GB standard dual-channel DDR4 memory<\/li>\n<li>Fast M.2 NVMe solid-state storage<\/li>\n<li>Two 2.5 Gigabit Ethernet connections<\/li>\n<li>Thunderbolt 4 and multiple USB interfaces<\/li>\n<li>Optional integrated GPIB for legacy instruments<\/li>\n<li>Windows and NI Linux Real-Time ordering options<\/li>\n<li>Front-panel PXI trigger-bus access<\/li>\n<li>Self-contained PXI Express system architecture<\/li>\n<\/ul>\n<h2>Frequently Asked Questions<\/h2>\n<h4>What is the PXIe-8842?<\/h4>\n<p>The PXIe-8842 is a four-wide PXI Express embedded controller that provides the processing, storage, networking and peripheral interfaces required to operate a compatible PXI Express chassis.<\/p>\n<h4>Which processor does the PXIe-8842 use?<\/h4>\n<p>It uses a 2.6 GHz Intel Core i5-11500HE processor with six cores and 12 MB of Smart Cache.<\/p>\n<h4>What is the maximum controller bandwidth?<\/h4>\n<p>The maximum controller-to-backplane bandwidth is 8 GB\/s.
