Description
📌 Product Overview
The NI PXIe-1075 is an 18-slot PXI Express chassis designed for modular test, measurement, automation, and data acquisition systems. It provides a high-bandwidth PXI Express backplane for installing a system controller together with PXI Express, PXI, CompactPCI Express, and CompactPCI peripheral modules.
The chassis includes 8 hybrid peripheral slots, 8 PXI Express peripheral slots, 1 dedicated PXI Express system timing slot, and 1 system controller slot. NI specifies system bandwidth of up to 4 GB/s and dedicated bandwidth of up to 1 GB/s per PXI Express slot in a single direction.
The PXIe-1075 is a legacy/discontinued NI chassis, but it remains relevant for maintaining existing PXI-based automated test and measurement systems.

🔧 Key Features
- 18-slot PXI Express chassis
- High-bandwidth PXI Express backplane
- 8 PXI Express peripheral slots
- 8 hybrid slots for broader module compatibility
- Dedicated PXI Express system timing slot
- Dedicated system controller slot
- Up to 4 GB/s system bandwidth

The PXIe-1075 backplane architecture is designed to support mixed module systems, allowing compatible PXI Express, PXI, CompactPCI Express, and CompactPCI hardware to be installed in the same chassis where the slot and module requirements are met.
🧪 Typical Applications
The NI PXIe-1075 is suitable for modular systems requiring multiple synchronized instruments and measurement modules.
Typical applications include:
- Automated test systems
- Electronic production testing
- Data acquisition systems
- RF and communication testing
- Semiconductor testing
- Industrial measurement
- Hardware-in-the-loop simulation
- Automated validation systems
- Aerospace and defense testing
- Laboratory instrumentation systems
- High-channel-count measurement platforms
The 18-slot design is particularly useful when multiple instruments, data acquisition modules, switching modules, timing devices, and controllers need to operate within one synchronized PXI platform.
🕒 Timing and Synchronization
PXI systems are widely used when multiple modules must operate with coordinated timing. The PXIe-1075 includes dedicated timing and synchronization resources through its PXI Express system timing architecture.
The chassis supports standard PXI and PXI Express timing resources, including a 10 MHz PXI reference clock and a 100 MHz PXI Express reference clock. This architecture helps synchronize compatible measurement and control modules installed within the chassis.
Before configuring a synchronized system, confirm the timing requirements of every installed module and verify which module is responsible for reference-clock or trigger generation.
🌬️ Cooling and Power
The PXIe-1075 uses forced-air cooling to support installed PXI modules. Cooling capacity and total chassis power requirements should be checked when multiple high-power modules are installed.
For system planning, consider:
- Total power consumption of all installed modules
- Cooling requirement of each module
- Controller power consumption
- Ambient operating temperature
- Airflow around the chassis
- Rack installation arrangement
- Empty-slot filler panels
NI chassis design guidance recommends considering both module power consumption and thermal requirements when configuring a PXI system.
🛠️ Installation Notes
Before installing modules into the PXIe-1075:
- Disconnect AC power.
- Inspect the backplane and slot connectors.
- Confirm the system controller is installed in the correct controller slot.
- Install PXI Express modules only in compatible slots.
- Check hybrid-slot compatibility before installing older PXI modules.
- Install timing-sensitive modules according to the system architecture.
- Use filler panels for unused slots where required.
- Confirm sufficient cooling clearance.
- Verify the total system power budget.
- Power up the chassis and check controller and module diagnostics.
Because the PXIe-1075 supports several module standards, physical compatibility alone does not guarantee complete system compatibility. The controller, module type, PCI Express link requirements, drivers, and application software should all be verified.
🔍 Inspection for Used or Surplus Equipment
For a used or surplus PXIe-1075 chassis, recommended inspection includes:
- Check the front and rear chassis panels.
- Inspect all 18 slot connectors.
- Check for bent backplane contacts.
- Inspect cooling fans for noise or abnormal operation.
- Test the AC power supply.
- Verify power and status indicators.
- Check the controller slot and timing slot.
- Inspect rack-mount points and chassis handles.
- Check for excessive dust or contamination.
- Perform a controlled power-up test.
If possible, test the chassis with a known compatible PXI controller and one or more verified PXI/PXIe modules.
