Home » » GX3348 Series   (PXI 6U)

6U PXI Multi-Channel Analog I/O PXI Card

  • Three programmable DC outputs, -20 VDC to +32 VDC
  • Available with a 4 x 48 or 4 x 64 relay matrix configuration
  • DC measurement capability on each channel
  • 500 mA maximum current output
  • External source input with switchable amplifier
  • Pulse / square wave generator option


The GX3348 is a multi-channel analog I/O 6U PXI card which provides (3) programmable sources, a ground source connection, a pulse / square wave generator (A version only) and a 4 x 48 or 4 x 64 matrix - allowing the user to route the 3 sources, or ground to any of the 48 or 64 I/O channels. In addition, each I/O channel can be connected to a 16-bit A to D converter, providing DC voltage measurement capability for each channel. The module also offers (8) static digital I/O for controlling  / monitoring a UUT's digital signals.


The 4 inputs to the switch matrix can be connected to the following sources:
  • Programmable -20 to +32 VDC source
  • External source (with amplifier or bypassed
  • Waveform generator (A version only)
  • Ground (0 V)

Each I/O channel also includes DC measurement capability; allowing each input channel to be monitored and facilitating module self-test. Combined maximum output current for all programmable sources is 500 mA. If using the external source inputs, 5 VDC or ground connection, maximum current is limited to 3 A. An onboard EEPROM contains the DAC’s and ADC’s calibration parameters.


The board is supplied with the GXPDO driver, 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®, C#, 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.
