They form the foundation of automated test, data acquisition, RF, semiconductor, automotive, aerospace and laboratory measurement systems.<\/p>\r\n\r\n    <p>Selecting the correct PXI or PXIe chassis requires more than counting available slots. Engineers must confirm module compatibility, controller architecture, per-slot bandwidth, aggregate system bandwidth, backplane segmentation, cooling capacity, timing resources, power input and future expansion requirements.<\/p>\r\n  <\/div>\r\n\r\n  <h3>What Does a PXI Chassis Do?<\/h3>\r\n\r\n  <p>A PXI chassis connects the system controller and measurement modules through a common backplane. The installed modules perform measurement, signal generation, switching, communication or control functions, while the chassis provides the infrastructure that allows them to operate as one synchronized system.<\/p>\r\n\r\n  <p>A complete <a class=\"product-link\" 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 system<\/a> normally includes:<\/p>\r\n\r\n  <ul>\r\n    <li>A PXI or PXIe chassis providing slots, power, cooling, clocks and trigger buses<\/li>\r\n    <li>An embedded <a class=\"product-link\" 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\/\">PXI controller<\/a> or remote-control connection<\/li>\r\n    <li>Compatible <a class=\"product-link\" 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\/%d0%bc%d0%be%d0%b4%d1%83%d0%bb%d0%b8-pxi\/\">PXI and PXIe modules<\/a><\/li>\r\n    <li>Instrument drivers and automated test software<\/li>\r\n    <li>Terminal blocks, cables, fixtures and signal accessories<\/li>\r\n  <\/ul>\r\n\r\n  <div class=\"note-box\">\r\n    <p>The chassis should be selected from the complete module and controller configuration. A chassis can provide enough physical positions while still having insufficient compatible slots, PCI Express bandwidth, power or cooling for the intended instruments.<\/p>\r\n  <\/div>\r\n\r\n  <h3>PXI Chassis vs PXI Express Chassis<\/h3>\r\n\r\n  <div class=\"table-wrap\">\r\n    <table>\r\n      <thead>\r\n        <tr>\r\n          <th>Selection Factor<\/th>\r\n          <th>Traditional PXI Chassis<\/th>\r\n          <th>\u0428\u0430\u0441\u0441\u0438 PXI Express<\/th>\r\n        <\/tr>\r\n      <\/thead>\r\n      <tbody>\r\n        <tr>\r\n          <td>Backplane Architecture<\/td>\r\n          <td>PCI-based PXI bus<\/td>\r\n          <td>PCI Express-based PXIe backplane with higher throughput<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Typical Instruments<\/td>\r\n          <td>Legacy DAQ, DMM, switching and communication modules<\/td>\r\n          <td>High-speed digitizers, RF instruments, FPGA modules, SMUs and modern DAQ hardware<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Data Bandwidth<\/td>\r\n          <td>Suitable for lower-rate measurement and instrument control<\/td>\r\n          <td>Designed for high-speed acquisition, streaming and parallel instrument operation<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Peripheral Slots<\/td>\r\n          <td>Traditional PXI peripheral slots<\/td>\r\n          <td>PXIe peripheral, hybrid peripheral and system timing slots depending on the model<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Controller<\/td>\r\n          <td>Compatible traditional PXI embedded or remote controller<\/td>\r\n          <td>PXIe embedded controller, MXI interface or integrated Thunderbolt connection<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Best Fit<\/td>\r\n          <td>Maintaining established production and legacy measurement systems<\/td>\r\n          <td>New systems requiring bandwidth, scalability and modern instrument support<\/td>\r\n        <\/tr>\r\n      <\/tbody>\r\n    <\/table>\r\n  <\/div>\r\n\r\n  <p>A PXIe hybrid slot can support PXIe modules and selected hybrid-compatible PXI modules.

Confirm the complete model, hardware revision and part number before ordering.<\/p>\r\n\r\n  <h3>How to Select an NI PXI Chassis<\/h3>\r\n\r\n  <h4>1. Identify the Required Module Types<\/h4>\r\n\r\n  <p>Begin with a complete list of the instruments to be installed. Record whether each product is traditional PXI, PXI Express, hybrid-compatible or requires a PXIe system timing slot.<\/p>\r\n\r\n  <p>A chassis may have enough total positions but an unsuitable combination of controller, PXI, PXIe, hybrid and timing slots. Check every module against the chassis slot map.<\/p>\r\n\r\n  <h4>2. Calculate the Required Slot Count<\/h4>\r\n\r\n  <p>Include the embedded controller or remote interface, measurement modules, switches, timing hardware and modules occupying more than one position. High-performance embedded controllers can also require an adjacent expansion position.<\/p>\r\n\r\n  <p>Reserve reasonable capacity for future channels or instruments. Filling every available slot during initial deployment can make later expansion unnecessarily difficult.<\/p>\r\n\r\n  <h4>3. Choose Embedded or Remote Control<\/h4>\r\n\r\n  <p>A conventional PXI or PXIe chassis normally provides a system-controller slot for an embedded controller or chassis-side MXI module. This architecture is suitable for self-contained production systems and flexible remote-control configurations.<\/p>\r\n\r\n  <p>Integrated remote-control chassis such as the PXIe-1083 and PXIe-1090 connect directly to a supported external computer. They do not use a conventional embedded PXIe controller.<\/p>\r\n\r\n  <p>Review <a class=\"product-link\" 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\/%d0%bc%d0%be%d0%b4%d1%83%d0%bb%d0%b8-pxi\/pxi-mxi-interfaces\/\">PXI MXI interfaces<\/a> when a workstation, desktop computer or server will control the chassis.<\/p>\r\n\r\n  <h4>4. Calculate System Bandwidth<\/h4>\r\n\r\n  <p>Estimate the combined sustained data rate produced by all high-speed instruments. Include active channels, sample rate, transferred bytes per sample and simultaneous input or output streams.<\/p>\r\n\r\n  <p>Compare the result with the bandwidth of each module slot, chassis segment and controller connection. Published aggregate system bandwidth does not mean that every slot can simultaneously transfer at that rate.<\/p>\r\n\r\n  <h4>5. Review PCI Express Segmentation<\/h4>\r\n\r\n  <p>Large PXIe chassis divide peripheral slots across PCI Express switches and segments. Several modules can share one upstream connection to the controller, creating contention even when each individual slot is compatible.<\/p>\r\n\r\n  <p>Place high-throughput digitizers, RF instruments, FPGA modules and storage devices according to the chassis backplane diagram. Slot placement should be part of the system design.<\/p>\r\n\r\n  <h4>6. Check Per-Slot Cooling<\/h4>\r\n\r\n  <p>PXI modules have different thermal requirements. General DAQ and switching modules may require relatively little cooling, while high-performance RF, digital pattern, FPGA and storage modules can require substantially more airflow.<\/p>\r\n\r\n  <p>Confirm the supported cooling capacity of the selected chassis and slot. Chassis such as the PXIe-1095 are appropriate when high-power modules require additional thermal headroom.<\/p>\r\n\r\n  <h4>7. Confirm Power Requirements<\/h4>\r\n\r\n  <p>Review both total chassis power and power available on each backplane rail. A system containing many individually compatible modules can still exceed the chassis power budget.<\/p>\r\n\r\n  <p>For DC installations, confirm input-voltage range, connector, current demand, grounding and power-source capacity. A DC chassis should not be selected solely because its model name includes \u201cDC.\u201d<\/p>\r\n\r\n  <h4>8. Evaluate Timing and Synchronization<\/h4>\r\n\r\n  <p>PXI chassis provide reference clocks, trigger buses and star-trigger resources. PXIe chassis can add differential clocking, PXIe synchronization resources and dedicated system timing slots.<\/p>\r\n\r\n  <p>If instruments must maintain phase or sample alignment, verify the timing capabilities of the chassis, modules and synchronization hardware. Sharing one chassis does not automatically make every instrument phase coherent.<\/p>\r\n\r\n  <h4>9. Consider Acoustic Noise and Installation<\/h4>\r\n\r\n  <p>Fan speed and cooling mode affect sound level. Quiet laboratory environments may benefit from chassis designed for lower acoustic noise, while production racks normally prioritize maximum cooling.<\/p>\r\n\r\n  <p>Also confirm chassis dimensions, rack-mount accessories, airflow direction, front and rear clearance, cable routing and access to removable power or fan assemblies.<\/p>\r\n\r\n  <h4>10. Verify Software Support<\/h4>\r\n\r\n  <p>NI PXI Platform Services identifies supported chassis and provides system-level configuration information. Check compatibility with the required operating system, controller, NI software and chassis firmware.<\/p>\r\n\r\n  <p>Legacy chassis may continue to operate with existing systems but can require older controllers, drivers or operating systems. Review the complete software environment before changing the chassis.<\/p>\r\n\r\n  <h3>PXIe Bandwidth Planning<\/h3>\r\n\r\n  <div class=\"table-wrap\">\r\n    <table>\r\n      <thead>\r\n        <tr>\r\n          <th>Bandwidth Requirement<\/th>\r\n          <th>Typical Instruments<\/th>\r\n          <th>Planning Priority<\/th>\r\n        <\/tr>\r\n      <\/thead>\r\n      <tbody>\r\n        <tr>\r\n          <td>Low<\/td>\r\n          <td>Switches, DMMs, industrial communication and temperature acquisition<\/td>\r\n          <td>Slot compatibility, channel count and software support<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Moderate<\/td>\r\n          <td>Multifunction DAQ, programmable power and mixed automated test<\/td>\r\n          <td>Per-slot links, controller performance and simultaneous activity<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>High<\/td>\r\n          <td>High-speed digitizers, digital instruments, RF and FPGA modules<\/td>\r\n          <td>Backplane segments, PCIe generation and controller link<\/td>\r\n        <\/tr>\r\n        <tr>\r\n          <td>Extreme<\/td>\r\n          <td>Multichannel RF, high-speed record\/playback and FPGA-intensive systems<\/td>\r\n          <td>Gen 3 topology, aggregate system bandwidth, slot placement, storage and cooling<\/td>\r\n        <\/tr>\r\n      <\/tbody>\r\n    <\/table>\r\n  <\/div>\r\n\r\n  <p>Bandwidth should be designed with operating margin. File-system activity, PCIe protocol overhead, memory transfers and other simultaneous module traffic can reduce the sustainable application rate.<\/p>\r\n\r\n  <h3>PXI Chassis Cooling and Airflow<\/h3>\r\n\r\n  <p>PXI chassis use forced-air cooling to remove heat from the controller and measurement modules. Correct operation depends on unobstructed air intake, adequate rear clearance, properly installed filler panels and an ambient temperature within the chassis specification.<\/p>\r\n\r\n  <p>Before installing a dense configuration:<\/p>\r\n\r\n  <ul>\r\n    <li>Confirm the cooling requirement of every installed module<\/li>\r\n    <li>Check whether supported slots provide 38 W, 58 W or higher cooling capacity<\/li>\r\n    <li>Use the correct fan mode for the application<\/li>\r\n    <li>Install filler panels in unused positions<\/li>\r\n    <li>Maintain the required front and rear airflow clearance<\/li>\r\n    <li>Avoid installing multiple high-power modules without reviewing thermal distribution<\/li>\r\n    <li>Monitor chassis fan and power-status indicators<\/li>\r\n  <\/ul>\r\n\r\n  <div class=\"note-box\">\r\n    <p>A module may be electrically compatible with a slot but thermally unsuitable for that chassis or fan mode. Power and cooling requirements must be verified independently from connector compatibility.<\/p>\r\n  <\/div>\r\n\r\n  <h3>Timing and Synchronization Resources<\/h3>\r\n\r\n  <p>PXI provides shared backplane timing resources that allow instruments to coordinate measurements without routing every clock and trigger through external front-panel cables.<\/p>\r\n\r\n  <p>Depending on the chassis and installed modules, synchronization resources can include:<\/p>\r\n\r\n  <ul>\r\n    <li>PXI 10 MHz reference clock<\/li>\r\n    <li>PXIe 100 MHz differential clock<\/li>\r\n    <li>PXI trigger bus lines<\/li>\r\n    <li>Star-trigger and differential star-trigger resources<\/li>\r\n    <li>Dedicated system timing slots<\/li>\r\n    <li>External reference clock and trigger connections<\/li>\r\n  <\/ul>\r\n\r\n  <p>Applications involving phase-coherent RF, synchronized digitizers, multichassis acquisition or precise event timing may require a dedicated synchronization module and additional clock-distribution cabling.<\/p>\r\n\r\n  <h3>Typical PXI Chassis Applications<\/h3>\r\n\r\n  <ul>\r\n    <li>Automated production and functional test systems<\/li>\r\n    <li>Semiconductor characterization and multisite device test<\/li>\r\n    <li>RF, microwave, radar and wireless validation<\/li>\r\n    <li>Automotive ECU and hardware-in-the-loop testing<\/li>\r\n    <li>Aerospace, avionics and defense-system validation<\/li>\r\n    <li>High-channel-count data acquisition<\/li>\r\n    <li>Sound, vibration and structural testing<\/li>\r\n    <li>Power electronics and battery validation<\/li>\r\n    <li>Scientific research and laboratory automation<\/li>\r\n    <li>High-speed data recording and playback<\/li>\r\n  <\/ul>\r\n\r\n  <h3>Legacy PXI Chassis Replacement<\/h3>\r\n\r\n  <p>Replacing a discontinued PXI chassis requires checking more than the number of slots. A newer chassis may use a different controller interface, hybrid-slot arrangement, backplane topology, cooling system or software environment.<\/p>\r\n\r\n  <p>Compare the following before approving a replacement:<\/p>\r\n\r\n  <ul>\r\n    <li>Traditional PXI or PXI Express architecture<\/li>\r\n    <li>System-controller and remote-control compatibility<\/li>\r\n    <li>Peripheral, hybrid and timing-slot positions<\/li>\r\n    <li>Backplane signaling and module connector compatibility<\/li>\r\n    <li>Per-slot and aggregate system bandwidth<\/li>\r\n    <li>Power supply and cooling capacity<\/li>\r\n    <li>AC or DC input requirements<\/li>\r\n    <li>Rack dimensions and installation accessories<\/li>\r\n    <li>Timing and trigger resources<\/li>\r\n    <li>Operating-system and NI Platform Services support<\/li>\r\n  <\/ul>\r\n\r\n  <p>For validated production equipment, sourcing the same chassis model can reduce module relocation, software changes and system requalification. A technically newer chassis should not automatically be treated as a drop-in replacement.<\/p>\r\n\r\n  <h3>PXI Chassis Procurement and RFQ Guide<\/h3>\r\n\r\n  <div class=\"solution-box\">\r\n    <p>Provide the following information for chassis selection and quotation:<\/p>\r\n\r\n    <ul>\r\n      <li>Required chassis model and complete part number<\/li>\r\n      <li>Existing controller or remote-control interface<\/li>\r\n      <li>Complete list of installed PXI and PXIe modules<\/li>\r\n      <li>Required slot count and planned expansion<\/li>\r\n      <li>Estimated aggregate data throughput<\/li>\r\n      <li>Module power and cooling requirements<\/li>\r\n      <li>AC or DC input requirement<\/li>\r\n      <li>Timing and synchronization requirements<\/li>\r\n      <li>Rack-mount, cable and accessory requirements<\/li>\r\n      <li>Operating system and NI software versions<\/li>\r\n      <li>New or pre-owned hardware preference<\/li>\r\n      <li>Required quantity, destination and delivery date<\/li>\r\n    <\/ul>\r\n  <\/div>\r\n\r\n  <p>For pre-owned chassis, request power-on testing, controller communication, slot enumeration, fan operation and inspection of the backplane and module guides. Where practical, the complete system should be tested with representative modules rather than evaluating only whether the chassis powers on.<\/p>\r\n\r\n  <h3>\u0427\u0430\u0441\u0442\u043e \u0437\u0430\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0435 \u0432\u043e\u043f\u0440\u043e\u0441\u044b<\/h3>\r\n\r\n  <h4>What is the difference between a PXI chassis and a PXIe chassis?<\/h4>\r\n\r\n  <p>A traditional PXI chassis uses a PCI-based backplane, while a PXIe chassis uses PCI Express links for higher data throughput. PXIe chassis can also include hybrid slots that support selected traditional PXI modules.<\/p>\r\n\r\n  <h4>Can traditional PXI modules be installed in a PXIe chassis?<\/h4>\r\n\r\n  <p>Only selected hybrid-compatible PXI modules can be installed in compatible PXIe hybrid slots. Check the module connector and chassis slot map because not every traditional PXI module is hybrid compatible.<\/p>\r\n\r\n  <h4>Can a PXIe module be installed in a traditional PXI chassis?<\/h4>\r\n\r\n  <p>No. PXIe modules require PXI Express-compatible connectors and backplane links that are not provided by a traditional PXI chassis.<\/p>\r\n\r\n  <h4>How many chassis slots do I need?<\/h4>\r\n\r\n  <p>Count the controller or remote interface, all measurement modules, timing hardware and any modules occupying more than one position. Add reasonable spare capacity for future expansion.<\/p>\r\n\r\n  <h4>Does every PXIe slot provide the same bandwidth?<\/h4>\r\n\r\n  <p>No. Slot bandwidth and PCI Express generation can differ, and several slots may share one upstream chassis segment. Consult the backplane diagram before placing high-throughput instruments.<\/p>\r\n\r\n  <h4>Can any embedded controller be installed in any PXIe chassis?<\/h4>\r\n\r\n  <p>No. The chassis must provide a compatible system-controller slot, adequate cooling and sufficient backplane bandwidth. Integrated remote-control chassis such as the PXIe-1083 and PXIe-1090 do not use a conventional embedded controller.<\/p>\r\n\r\n  <h4>When should I choose a Thunderbolt PXIe chassis?<\/h4>\r\n\r\n  <p>A Thunderbolt chassis is useful when the system should be controlled by a supported laptop or workstation and only a small number of modules are required. Confirm computer, port, cable, operating-system and bandwidth compatibility.<\/p>\r\n\r\n  <h4>Why are filler panels important?<\/h4>\r\n\r\n  <p>Filler panels help direct cooling airflow through installed modules and reduce dust entry. Operating a chassis with unused slots left open can reduce cooling performance.<\/p>\r\n\r\n  <h4>Why does a PXI chassis show a red or flashing power indicator?<\/h4>\r\n\r\n  <p>A red or flashing indicator can identify a power, fan, temperature or voltage-rail condition depending on the chassis model. Consult the exact chassis manual and remove power before inspecting or reseating hardware.<\/p>\r\n\r\n  <h3>Recommended NI PXIe Chassis<\/h3>\r\n\r\n  <div class=\"related-info\">\r\n    <p>Consider the <a class=\"product-link\" href=\"https:\/\/pxisource.com\/ru\/product\/pxie-1090\/\">PXIe-1090<\/a> for an ultra-compact Thunderbolt system, the <a class=\"product-link\" href=\"https:\/\/pxisource.com\/ru\/product\/%d0%bf%d0%b8%d0%ba%d1%81%d0%b5%d0%bb%d1%8c-1083\/\">PXIe-1083<\/a> for a larger Thunderbolt-controlled configuration, the <a class=\"product-link\" href=\"https:\/\/pxisource.com\/ru\/product\/pxie-1092\/\">PXIe-1092<\/a> for high-bandwidth medium-density systems, or the <a class=\"product-link\" href=\"https:\/\/pxisource.com\/ru\/product\/%d0%bf%d1%8c%d0%b5-1095\/\">PXIe-1095<\/a> for high-density and high-power PXIe applications.<\/p>\r\n  <\/div>\r\n\r\n  <h3>Related NI PXI Components<\/h3>\r\n\r\n  <p>Pair the selected chassis with a compatible <a class=\"product-link\" 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\/\">PXI controller<\/a>, appropriate <a class=\"product-link\" 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\/%d0%bc%d0%be%d0%b4%d1%83%d0%bb%d0%b8-pxi\/\">PXI \u043c\u043e\u0434\u0443\u043b\u0438<\/a> and any required <a class=\"product-link\" 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\/%d0%bc%d0%be%d0%b4%d1%83%d0%bb%d0%b8-pxi\/pxi-mxi-interfaces\/\">MXI remote-control interfaces<\/a>.<\/p>\r\n\r\n  <h3>NI PXI Chassis from PXISOURCE<\/h3>\r\n\r\n  <p>PXISOURCE supports engineers, laboratories, system integrators and procurement teams with PXI chassis selection, controller and module compatibility review, backplane planning, current-system sourcing and legacy chassis replacement.
