Switch Matrix ISA Card

  • High density switching
  • Built in 12-bit, 300 K sample / s A/D
  • Extensive built-in self-test
  • Groups can be connected to form up to 2 x 64 or 8 x 16 switch matrix
  • Four individual range groups allow multiple configurations
  • Pairs of groups can be software-configured for differential switching


The GT6416 Series armature relay switch matrix are ISA-based PC boards that provide either differential or single-ended input capability and are configurable via software commands. The GT6416A-SM has four groups of 1 x 16 switch matrix, and the GT6416B-SM has four groups of 2 x 16 switch matrix.


The GT6416-SM Series consists of up to four switching groups - A through D - that support switching of any of two rows to any of 16 columns. Each switching group can connect to an adjacent group via “jumpers” (either horizontally or vertically). In addition, groups A and B and groups C and D can be configured as a 2 x 16 differential switch matrix via software commands. Typical configurations include:
  • Four groups of 1 x 16 (GT6416A-SM)
  • Four groups of 2 x 16 (GT6416B-SM)
  • Two groups of 4 x 16 Single-ended
  • One group of 2 x 64 Single-ended
  • One group of 2 x 32 Single-ended
Mixed configurations of single-ended and differential switching can be used simultaneously. The GT6416 Series has a built-in 12-bit, 300 kHz A/D converter. The converter can be connected by software commands to each one of the switching groups, allowing differential or single-ended measurements to be performed. An optional self-test connector can be attached externally enabling a complete self-test of the GT6416.

Programming and Software

The board is supplied a 32-bit DLL driver. Various interface files provide access to the DLL from programming tools and languages such as ATEasy, LabVIEW, C/C++, Microsoft Visual Basic®, Delphi, and more. The available virtual panel can be used to interactively adjust and control the instrument from a window that displays the current instrument settings and measurements.
On-Line help file and PDF User's Guide provides documentation that includes instructions for installing, using and programming the board.
