  • 6U PXI Instrument


The GX6616 is a 6U PXI switch matrix board that provides either differential or single-ended multiplexing capability through software commands, along with six groups of 2 x 16 that may be used in various configurations.


The GX6616 consists of six switching groups, A through F, which provide connections between two rows and 16 channels. Each switching group can be connected either horizontally or vertically to an adjacent group via on-board jumpers. Typical configurations include:
  • Six groups of 2 x 16
  • Three groups of 4 x 16
  • Three groups of 2 x 32
  • One group of 2 x 96
An optional self-test adapter is available externally to perform a complete self-test of the GX6616.

Programming and Software

The board is supplied with the GXSW library, a software package that includes a virtual instrument panel, and a Windows 32/64-bit DLL driver library and documentation. The virtual panel can be used to interactively program and control the instrument from a window that displays the instrument’s current settings and status. In addition, interface files are provided to support access to programming tools and languages such as ATEasy, LabView, LabView/Real-Time, C/C++, Microsoft Visual Basic®, Delphi, and Pascal. An On-Line help file and PDF User's Guide provides documentation that includes instructions for installing, using and programming the board.
A separate software package - GtLinux - provides support for Linux 32/64 operating systems.
