Architecture

The Marvin Test Solutions PXI GX6384 is a 384-crosspoint high-speed configurable switch matrix card that fits in a single PXI/CompactPCI 3U bus slot. The GX6384 offers ultrahigh-density switch configurations in PXI with the ability to create up to 6x64 switch matrix. The GX6384 is offered in tree configurations: two groups of 2x32 (GX6384-1), two groups of 4x32 (GX6384-2) or two groups of 6x32 (GX6384-3). All three board configurations can be programmatically changed to a single group with same number of rows but double the number of columns as single group of 2x64 (GX6384-1), single group of 4x64 (GX6384-2) or single group of 6x64 (GX6384-3). That capability enables unprecedented flexibility for different testing requirements. Featuring compact reed relays with high switching speeds provides maximum throughput in a test system for signals up to 100 VDC/100 VAC or 0.5 A. combined with user friendly 78 pin sub-D type interface connector.

Switch Matrix Groups

The GX6384 all configurations have two switching groups A and B. The two switching groups can be combined to create a single group with double the number of columns.

Ground and Guard

All the shielding on the GX6384 board is connected to a chassis signal. JP1 can be installed to connect the chassis and Ground.
