A component of the GENASYS switching subsystem, the GX6256 switch card is one of several different switch cards which can be installed in the GX7016 or GX7017 chassis. The GENASYS switching subsystem offers a new level of high performance, high density switching for board and system level functional test. Based on the 6U PXI architecture, the GENASYS architecture incorporates a modular switch matrix and multiplexer architecture which supports up to 4608 multiplexed, hybrid I/O pins. Up to 128 external resources can be connected to any of the test system’s receiver I/O pins via a high performance, internal 16 wire matrix bus. For digital test capability, the GENASYS switching subsystem can be connected to a digital subsystem such as Marvin Test Solutions’ GX5960 digital subsystem, providing hybrid pin capability for each multiplexed I/O pin. Up to 288 digital channels are supported by the switching subsystem. The GX7016 and GX7017 chassis incorporates the MAC Panel 6U SCOUT receiver with each switch card providing a “cable-less” connection to the receiver connectors – eliminating the need for cable harnesses and the associated reliability issues that come with cabled solutions. The result is a system interconnect design that is cost effective, reliable, and maintainable.

DESCRIPTION

The GX6256 provides signal routing from the GX7016’s of GX7017’s internal backplane to the receiver interface as well as providing an alternate, high bandwidth connection for digital resources. The GX6256 MultiMatrix™ switch card is an extended 6U PXI module with direct connection to the receiver interface. The module combines a 16×16 matrix with (16) 2:16 multiplexers. The result is a switch card that can support up to 256 multiplexed signals from the 16 wire bus. Additionally, a secondary bus is included, providing the ability to route (2) resources to each group of 16 I/O pins within a mux group. The GX6256 also supports the ability to select an analog or digital resource (GX5960 digital subsystem) for each of the 16 inputs / outputs.

SOFTWARE

See GX7016 or GX7017 for more information regarding GXCHASSIS and GXSW software provided with this card. For end to end to signal routing, Marvin Test Solutions’ SwitchEasy is used to control and manage overall signal switching. SwitchEasy provides end to end signal routing by having the user simply define the resource and receiver pin or UUT connections, simplifying overall application development and deployment time.
