The GX7920 is a single-slot 6U embedded PXI controller for use with Geotest's GX7100 PXI combo chassis and GX7000 PXI chassis. The GX7920 is available with a variety of CPU and memory configurations and a full range of peripherals.

The GX7920 PXI controller uses a single slot in a Geotest chassis because all storage devices (i.e. hard disk, floppy disk and CD-ROM drives) are mounted in the chassis, and connected via IDE or SATA interfaces. A CompactFlash type II socket is included on the controller.
