  • Operational Silence: When operating at the Auto or High fan setting within a 23°C ambient environment, the chassis maintains a low acoustic noise level of less than 40 dBA at the operator level, ensuring a comfortable workspace.
  • Robust Temperature Range: The chassis is designed for operation in challenging environments, with an operational temperature range spanning from 0°C to +50°C.
  • Reliable Storage Conditions: With a storage temperature range of -20°C to +60°C, the chassis ensures data integrity and equipment protection during storage or transit.

The GX7100e Series comprises 14-slot combination PXIe chassis, offering a space-saving solution for various PXIe applications. These chassis can accommodate a 3U PXIe embedded controller or a MXI express controller, along with a combination of 3U and 6U PXI/PXIe instruments, all within a compact 4U rack space. The unique design includes seven 6U slots and seven 3U slots positioned horizontally, reducing the chassis’s overall size while providing the flexibility and high-density capability required for a wide range of PXI/PXIe applications. The backplane architecture supports Gen 2, 4×4 PCI Express bus signaling, and is compatible with both x1 and x4 system controllers. With a combination of PXI-1, Hybrid, and Express slots, the GX7100e Series offers unparalleled flexibility for general-purpose and high-bandwidth testing needs.


The GX7100e Series is equipped with a range of features and options, including an innovative forced-air cooling system driven by eight 20 CFM fans controlled by built-in temperature sensors. These fans ensure proper airflow according to PXI revision 2.1 specifications, regardless of the type or number of instruments in use. The chassis also provides additional cooling for the system power supply.

The GX7100e Smart Chassis supports the monitoring of internal chassis temperatures, system power supply voltages, and offers the ability to program or map PXI trigger lines from one PCI segment to another. Users can customize temperature monitoring settings for specific warning and shutdown limits. All user configurations can be stored in non-volatile memory, serving as the default setup for regular chassis operation.

For applications requiring efficient cable routing to and from the rear of the chassis, the GX7100e Series offers an integrated 2U cable tray, a hinged front-panel compatible with popular mass interconnect devices, optional openings for cable routing at the top and bottom of the chassis, and the option to recess PXI instruments by 2.5″ or 5″.
