Marvin Test Solutions' GT1648 D/A board is designed specifically for applications where multiple analog outputs are required. The GT1648 offers precision signal sourcing performance and quality at an economical price.


The GT1648 is organized in groups of eight channels. Each group is programmed and triggered independently. All groups can be updated simultaneously. The GT1648 channels provide single-ended voltage output. All channels power up to 0 V to prevent inadvertent damage to external equipment. The connection to the GT1648 is through a single 78-pin D-Type connector. A mating connector is supplied with the board.

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.
