PXIe-1065

PXIe-1065 18-Slot PXI Express Chassis

Земля NI PXIe-1065 is an 18-slot PXI Express chassis designed for automated test systems that need to combine conventional PXI instruments with PXI Express modules. It provides one system controller slot and 17 peripheral positions in a full-width rack-mountable enclosure.

The peripheral layout consists of nine conventional PXI slots, four PXI hybrid slots, three PXI Express slots and one PXI Express system timing slot. This mixed architecture makes the PXIe-1065 particularly valuable for upgrading established PXI systems without replacing every existing measurement module.

With up to 3 GB/s aggregate system bandwidth, 701.5 W of usable DC output power, 38.25 W cooling capacity per peripheral slot and advanced timing resources, the PXIe-1065 supports high-density production testing, electronic validation, multichannel data acquisition and hardware-in-the-loop applications.

18-Slot Mixed PXI and PXI Express Architecture

The PXIe-1065 contains 18 functional chassis positions. One position is reserved for the system controller, while the remaining 17 positions support peripheral and system timing modules.

The controller area includes three system expansion positions to accommodate compatible multi-slot embedded controllers and remote-control interfaces. These expansion positions belong to the controller area and are not counted as peripheral instrument slots.

The mixed backplane allows a test system to retain a large number of conventional PXI modules while adding newer PXI Express instruments where greater bandwidth is required.

Nine Conventional PXI Slots

Nine peripheral positions provide conventional PXI connections. These slots are intended for PXI and compatible CompactPCI modules that use the parallel PCI bus.

This unusually high number of conventional PXI slots makes the PXIe-1065 well suited to legacy system migration, long-life production testers and HIL systems containing validated PXI hardware.

Typical modules installed in these positions include switch matrices, relay modules, digital multimeters, serial interfaces, multifunction DAQ devices and industrial communication modules.

PXI Express-only modules cannot use a conventional PXI slot because the required PCI Express connector and electrical link are not present.

Four PXI Hybrid Slots

Four peripheral positions use PXI hybrid connectors. These slots can accept PXI Express modules and compatible conventional PXI or CompactPCI instruments.

Hybrid slots give system designers flexibility when allocating scarce PXI Express positions. A hybrid-ready conventional PXI module can use a hybrid position, or the position can be reserved for a newer PXI Express device.

Some early PXI modules use rear connectors that are incompatible with hybrid slots. Verify physical connector compatibility before installation and never force a module into the backplane.

Three PXI Express Slots

Three standard peripheral positions are designed for PXI Express modules. These slots provide PCI Express-based communication with the system controller.

They are suitable for digitizers, FPGA modules, high-speed data acquisition devices, waveform generators and communication interfaces that require greater bandwidth than the conventional PCI bus can provide.

Slot assignments should be planned before installation because only the hybrid and PXI Express positions support PXI Express modules.

PXI Express System Timing Slot

The dedicated system timing slot provides access to PXI and PXI Express timing resources. A compatible timing module can manage reference clocks, star triggers and system synchronization.

This position supports PXI_CLK10_IN, PXIe_SYNC_CTRL, PXI star triggers and PXI Express differential star trigger resources.

The timing slot is useful for applications requiring a common reference across many instruments or synchronization with another chassis, external instrument or facility timing source.

3 GB/s System Bandwidth

The PXIe-1065 provides up to 3 GB/s of aggregate system bandwidth. This supports a combination of conventional PXI instruments and moderate-bandwidth PXI Express modules.

The actual throughput available to an individual instrument depends on its slot type, interface link, controller and simultaneous activity from other modules.

When several high-speed PXI Express instruments stream continuously, calculate their combined sustained data rate. A newer high-bandwidth chassis may be preferable if the system can exceed 3 GB/s.

Embedded and Remote Control

A compatible embedded controller can be installed directly in the system position, creating a self-contained PXI test platform with onboard processing, memory, storage and network interfaces.

The chassis can also use a compatible remote-control module to connect to an external computer or workstation. A remote system requires the correct chassis interface, host adapter and cable.

Controller selection should consider processing performance, operating-system support, physical width, interface bandwidth, power consumption and long-term software compatibility.

PXIe-1065 Technical Specifications

701.5 W Usable DC Power

The PXIe-1065 provides a maximum of 701.5 W of usable DC output power. The combined power available from the +3.3 V, +5 V and +12 V rails is limited to 699 W.

This power capacity supports a system controller and a large collection of conventional PXI and PXI Express peripheral modules.

Power planning must consider both total wattage and the current available from each individual voltage rail.

A system can remain below 701.5 W total while exceeding the current capacity of a particular rail. This is especially important in mixed-generation systems because older PXI modules often draw more power from +5 V, while newer PXI Express modules rely more heavily on +12 V and +3.3 V.

System Controller Power Capacity

The system controller position supports up to 140 W of dissipation. Total current supplied to the system position should not exceed 45 A.

High-performance embedded controllers may consume a substantial portion of the available power. Include the controller in all chassis-level and rail-level power calculations.

When using remote control, verify the chassis-side controller’s power requirement and ensure that the selected interface provides sufficient bandwidth.

38.25 W Cooling per Peripheral Slot

Each peripheral position supports a maximum module dissipation of 38.25 W. This rating applies to conventional PXI, hybrid and PXI Express positions.

Total unused power does not increase the cooling capacity of an individual slot. A module requiring more than 38.25 W should not be installed even when several other positions are empty.

Use filler panels over unused slots to preserve the intended airflow pattern and prevent warm air from bypassing populated modules.

Three 165 CFM Module-Cooling Fans

The PXIe-1065 uses three 165 CFM fans to create positive-pressure cooling for installed controllers and peripheral instruments.

Air enters through the bottom-rear section of the chassis, travels upward through the modules and exits through openings along both sides and the top.

The power supply uses two integrated fans with right-side intake and left-side exhaust. Keep all intake and exhaust areas clear of cables, rack panels and neighboring equipment.

Auto and High Fan Settings

The chassis provides automatic and maximum-speed fan modes. Auto mode adjusts fan speed according to internal thermal conditions and helps reduce acoustic noise.

High mode supplies maximum airflow continuously. It is recommended for densely populated configurations, elevated ambient temperatures and installations where maximum thermal margin is required.

The specified sound-pressure level is approximately 45.0 dBA in Auto mode at ambient temperatures up to approximately 30°C and 63.3 dBA in High mode.

Short-Circuit and Overload Protection

All power-supply outputs include short-circuit and overload protection with automatic recovery. The +3.3 V and +5 V rails include overvoltage protection clamped approximately 20% to 30% above nominal output voltage.

Protection circuitry is designed for abnormal conditions and should not be treated as a substitute for correct module selection, power planning or maintenance.

Replaceable Power-Supply Shuttle

The chassis uses a removable power-supply shuttle with a specified mean time to repair of less than five minutes.

This service-oriented design can reduce downtime in production systems and long-running validation equipment.

Disconnect the AC cable before servicing the chassis. Replacement should be performed by qualified personnel using the correct power-supply assembly for the hardware revision.

External 10 MHz Reference Input

The rear-panel BNC input accepts a 10 MHz reference clock with frequency accuracy within ±100 ppm. It supports sine-wave or square-wave input amplitudes from 200 mVpp to 5 Vpp.

A compatible timing module can also provide a 3.3 V or 5 V TTL clock through PXI_CLK10_IN in the system timing slot.

The chassis adds no more than 1 ps RMS phase jitter over the specified 10 Hz to 1 MHz range when distributing the external clock through the backplane.

External 10 MHz Reference Output

The rear-panel reference output provides a 10 MHz square wave with specified accuracy of ±25 ppm.

Output amplitude is approximately 1 Vpp ±20% into a 50 Ω load or approximately 2 Vpp when unloaded. Output impedance is 50 Ω ±5 Ω.

This signal can synchronize compatible external instruments or provide a common reference to another timing device.

PXI Star Trigger Resources

The conventional PXI star-trigger architecture provides point-to-point trigger connections between the system timing slot and peripheral positions.

Maximum PXI star-trigger slot-to-slot skew is 250 ps. This supports coordinated acquisitions and signal-generation events across compatible PXI modules.

PXI Express Differential Star Triggers

The chassis supports PXIe-DSTARA, PXIe-DSTARB and PXIe-DSTARC differential star trigger resources.

Maximum slot-to-slot skew is 150 ps, maximum differential skew is 25 ps and the specified differential impedance is 100 Ω ±10%.

Compatible timing modules and PXI Express instruments can use these resources for low-skew triggering and clock distribution.

Rear-Panel Remote Power Control

A rear-panel nine-pin D-Sub connector and power-mode switch support remote control of the internal chassis power supply.

This feature is useful in automated racks where the chassis must start or shut down as part of a coordinated system-level power sequence.

The external control circuit must follow the official connector pinout. Incorrect wiring can prevent startup or damage connected control hardware.

0°C to 55°C Operation

The PXIe-1065 has an operating-temperature range from 0°C to 55°C. This supports laboratory, production and controlled industrial installations.

Internal temperature depends on the installed module load, fan mode, filter condition, rack ventilation and heat generated by adjacent equipment.

PXIe-1065 Part Number and Accessories

PXIe-1065 Part Number

A common ordering part number associated with the PXIe-1065 is 779730-01. Confirm the complete model and part number printed on the chassis label when sourcing a replacement for an existing system.

Quotation contents can vary. Verify whether the offer includes only the chassis or also contains a controller, timing module, power cord, rack hardware and filler panels.

Choosing an Embedded Controller

An embedded controller creates a self-contained PXI system and reduces the number of external interface cables.

The controller must fit the available system expansion area, dissipate no more than 140 W and remain within the chassis’s electrical limits.

Selection factors include processor performance, memory, storage, operating system, network connectivity, installed software and lifecycle requirements.

Choosing a Remote-Control Interface

A remote-control module allows the chassis to use the processing, storage and graphics resources of an external desktop computer or workstation.

The complete connection requires a compatible host adapter, chassis-side interface and cable. Interface bandwidth should be evaluated against the chassis’s 3 GB/s system capability.

Selecting a Timing Module

A timing module installed in the dedicated system timing position can distribute clocks and triggers across the chassis or synchronize it with external equipment.

Select the timing device according to the required oscillator stability, external reference format, GPS, IRIG, IEEE 1588 and multi-chassis synchronization requirements.

Rack-Mounting Accessories

The chassis can use front and optional rear rack-mounting hardware. Rear support is recommended because of its approximately 467.4 mm depth and 12.8 kg weight.

Rack installation must preserve access to side, top and rear ventilation openings. Support the chassis during installation rather than relying only on the front rack ears.

Checking a Used PXIe-1065

Inspect the backplane connectors, module guides, system timing position, cooling fans, AC inlet, circuit breaker and remote power connector.

Test both conventional PXI and PXI Express positions with known-compatible modules. Confirm that the controller identifies every installed instrument correctly in NI MAX.

Ask whether the power-supply shuttle, controller, filler panels and rack hardware are included and whether the chassis has been tested under load.

Legacy PXI System Migration

The nine conventional PXI slots are the defining advantage of the PXIe-1065. They allow an established system to retain numerous PXI instruments while adding PXI Express capability.

This can reduce migration cost when the existing modules, cables, test fixtures and software have already been validated for production use.

High-Density Automated Test Equipment

The chassis can accommodate 17 peripheral instruments covering signal generation, switching, acquisition, power control and communication.

A centralized embedded or external computer can configure each instrument and execute automated test sequences through LabVIEW, TestStand or another supported environment.

Production Functional Testing

Production testers often use conventional PXI switches, digital multimeters and communication interfaces that remain technically suitable after many years.

The PXIe-1065 allows these devices to operate in the same chassis as newer PXI Express digitizers or DAQ modules, extending the usable life of the test architecture.

Multichannel Data Acquisition

Multiple PXI and PXI Express DAQ modules can measure voltage, current, temperature, strain, pressure, vibration and digital signals.

System designers should calculate the combined acquisition rate and determine whether the 3 GB/s aggregate bandwidth is sufficient for continuous streaming.

Digital Multimeter and Switching Systems

A PXI digital multimeter combined with matrix switches and multiplexers can measure hundreds of DUT test points automatically.

Switch-heavy systems often require many physical slots while generating moderate backplane traffic, making the PXIe-1065 well suited to these applications.

Hardware-in-the-Loop Testing

The chassis can integrate analog I/O, digital I/O, vehicle networks, fault insertion switches, timing devices and FPGA modules.

Its conventional PXI capacity is useful for maintaining HIL systems built around older automotive and industrial interface cards.

RF and Wireless Testing

PXI Express RF instruments can be installed in compatible hybrid or PXIe slots, while conventional PXI switches and control modules use the parallel PCI positions.

The external 10 MHz connections and dedicated timing slot can distribute a common reference throughout the RF test system.

Aerospace and Defense Testing

Avionics interfaces, switching systems, data acquisition devices and timing modules can be combined in the chassis for aerospace subsystem testing.

The complete system must follow applicable grounding, safety, environmental and qualification requirements.

Laboratory Automation

The PXIe-1065 provides a flexible platform for laboratories with a large inventory of conventional PXI hardware.

Individual modules can be upgraded over time while the chassis continues to support established instruments and test software.

PXIe-1065 Installation Workflow

Step 1: Inventory All Modules

Identify every conventional PXI, hybrid-compatible and PXI Express module. Record each device’s connector type, physical width, power demand, cooling requirement and data-transfer rate.

Step 2: Create an Accurate Slot Map

Assign conventional PXI modules to the nine PXI positions or compatible hybrid positions. Reserve PXIe slots for instruments that require PCI Express connectivity.

Reserve the system timing slot for the timing module when advanced synchronization is required.

Step 3: Calculate the Power Budget

Add the current required on the +3.3 V, +5 V, +12 V, -12 V and auxiliary rails. Confirm that total demand remains below 701.5 W and the combined principal-rail load remains below 699 W.

Step 4: Calculate Cooling Requirements

Verify that no peripheral module requires more than 38.25 W of slot cooling and that the controller remains below its 140 W dissipation limit.

Step 5: Calculate System Bandwidth

Estimate the simultaneous sustained throughput of all PXI Express modules. Compare the total with the chassis’s 3 GB/s aggregate bandwidth.

Step 6: Prepare the Rack

Use appropriate front and rear support hardware. Preserve ventilation space around the bottom-rear intake, side vents and top exhaust.

Step 7: Disconnect AC Power

Turn off the chassis and unplug its power cord before installing or removing any module.

Step 8: Install the Controller

Insert the embedded or remote controller into the system position and required expansion positions. Fully seat its connectors and tighten the front-panel screws.

Step 9: Install the Timing Module

When required, install the compatible timing device in the dedicated system timing slot and configure the intended reference-clock and trigger sources.

Step 10: Install Peripheral Modules

Install each instrument in its assigned compatible slot. Close the injector/ejector handle and secure the module front panel.

Step 11: Install Filler Panels

Cover every unused position to maintain cooling airflow, electromagnetic shielding and backplane protection.

Step 12: Configure Fan and Power Modes

Select Auto or High fan mode according to the module load. Configure the rear power-mode switch for local or remote startup control.

Step 13: Connect External Timing

If required, connect the 10 MHz input or output using a suitable 50 Ω BNC cable. Verify signal level, termination and reference direction.

Step 14: Install Drivers and Verify Operation

PXIe-1065 Troubleshooting

The PXIe-1065 Does Not Power On

Check the AC supply, power cord, 12 A circuit breaker, front power switch and rear power-mode configuration.

If remote power control is enabled, verify the nine-pin D-Sub connection and external control circuit.

The Embedded Controller Does Not Start

Disconnect power and reseat the controller. Verify memory, storage, physical width and total controller power.

A Conventional PXI Module Is Not Detected

Confirm that the module is installed in one of the nine conventional PXI positions or a compatible hybrid slot. Check the driver and operating-system support.

A PXI Express Module Is Not Detected

Verify that the module is installed in one of the three PXIe positions, a compatible hybrid position or the timing position when allowed.

A PXI Express module cannot communicate through a conventional PXI-only slot.

A Module Does Not Fit in a Hybrid Slot

The module may use an older connector that is not hybrid-compatible. Do not force it into the backplane or remove connector keys.

The Chassis Reports Excessive Temperature

Inspect all three cooling fans and ventilation openings. Install filler panels and switch the fan selector to High.

Confirm that every peripheral module requires no more than 38.25 W of cooling.

The Chassis Shuts Down Under Load

Recalculate total power and each rail’s current. Pay particular attention to +5 V demand from older conventional PXI modules.

Remove modules and reinstall them individually to identify the overloaded rail or defective device.

The External 10 MHz Reference Is Not Recognized

Confirm that the reference is 10 MHz within ±100 ppm and that its amplitude remains between 200 mVpp and 5 Vpp.

Check the chassis and timing-module reference-source configuration.

The 10 MHz Output Level Is Unexpected

Verify the load termination. The output is approximately 1 Vpp into 50 Ω and approximately 2 Vpp when unloaded.

Measurements Are Not Synchronized

Review PXI_CLK10, PXIe_CLK100, PXIe_SYNC100 and star-trigger routing. Confirm that each instrument supports the selected resource.

System Bandwidth Is Lower Than Expected

Check the controller, remote interface, module slot and storage performance. The chassis provides up to 3 GB/s aggregate bandwidth, but conventional PXI slots operate through the parallel PCI architecture.

The Power Supply Requires Replacement

Use the correct power-supply shuttle for the chassis revision. Disconnect AC power and follow the official service procedure.
