3U / 6U PXIe Chassis

  • 14-slot 3U / 6U PXI Express combo chassis with 4x4 Gen2 backplane
  • Accommodates a single slot 3U PXIe controller, one 3U PXIe, three 3U hybrid, two PXI-1 and seven 6U hybrid slot compatible instruments
  • Built-in hard disk drive for embedded controller configurations
  • Integral Smart functions provide internal temperature monitoring, power supply monitoring, fan control and PXI trigger mapping
  • Optional cable tray, recessed card cage, and hinged front panel configurations for mass interconnect devices


The GX7100e Series are 14-slot combination PXIe chassis that accommodate a 3U PXIe embedded controller or a MXI express controller as well as 3U & 6U PXI / PXIe insruments in 4U of rack space. The GX7100e’s unique format includes seven 6U slots and seven 3U slots arranged horizontally to reduce the overall size of the chassis, providing the versatility and high-density necessary to address many PXI / PXIe applications and requirements. The backplane architecture supports Gen 2, 4x4 PCI Express bus signaling and the use of both x1 or x4 system controllers. By offering a combination of PXI-1, Hybrid, and Express slots, the GX7100e offers users the ultimate in flexibility for general purpose as well as high bandwidth test needs.


The GX7100e Series offers a full range of features and options including an innovative forced-air cooling system comprised of eight (8) 20 CFM fans controlled by built-in temperature sensors. The fans provide airflow according to PXI revision 2.1 specifications. This cooling configuration provides optimum cooling for the chassis regardless of the type or number of instruments used. Additional cooling is provided for the system power supply.

The GX7100e Smart Chassis supports the monitoring of internal chassis temperatures and system power supply voltages as well providing the ability to program or map each PXI trigger line from one PCI segment to another. In addition, the user can program the temperature monitoring function for specific warning and shutdown limits. All user specific setups can be stored in non-volatile memory as a user configuration and can be used as the default setup for normal chassis operation.

For applications requiring mass interconnect and cable routing to/ from the rear of the chassis, the GX7100e Series offers the ideal system solution. These chassis include an integrated 2U cable tray, a hinged front-panel that accommodates all popular mass interconnect devices, optional openings at the top and bottom of chassis for cable routing, and recessed PXI instruments (recessed by 2.5" or 5"). The combination of front panel and the recessed instruments provides up to 8" of space for interface wiring.

The GX7100e Series provides 650 W of system power and complies with the PXI Hardware Specification PXI-5, Rev. 2.0.


Slot 1 (3U) is dedicated to the system controller (embedded or remote, using a PXIe bus expander). Slot 2 can be used by a PXIe or cPCIe peripheral.Slots 3 and 4 support 3U PXI-1 peripherals and slots 5-7 support 3U PXI hybrid slot compatible peripherals. Slots 8 -14 support 6U hybrid slot compatible peripherals.

Programming and Software

The chassis is supplied with the GxChassis software which provides software libraries and a driver, programming examples, virtual panel application and documentation. The virtual panel provides a way to control, configure and display the smart chassis' features, including temperature monitoring, trigger line mapping, and power supply voltage monitoring. A 32/64-bit Windows DLL driver is provided with various interface files for accessing the DLL functions from programming tools and languages such as ATEasy, LabVIEW, C/C++, Microsoft Visual Basic®, Delphi, and more. A User's Guide provides documentation that includes instructions for installing, using and programming the chassis. Support for Linux for the chassis is provided using a separate software package - GtLinux.
