4 Channel PXI Source Measure Unit (SMU)

4 Channel PXI Source Measure Unit (SMU), ±20V, 250mA per Channe

  • 4 isolated, common ground SMU channels
  • 4-quadrant operation: ±20 V, ±1 A
  • 7 current ranges, ±2.5 uA to ±1 A full scale
  • Up to 1A capability on one channel
  • 24-bit ADC's,18-bit DAC's
  • Supplied with a full featured API and UI
  • PXI hybrid slot compatible


The GX3104 is a precision 3U PXI module that forces and senses both voltage and current over a range of ±20 V and up to ± 1 A ( channel 1) with channels 2- 4 capable of supplying up to 500 mA. Total available output current from the module is 1A.  The four channels are electrically isolated from the PXI power supply and share a common, isolated ground.    


The GX3104 employs 18-bit DACs for the sourcing of voltage and current. There are 7 current ranges in decade steps, ranging from ±1 A FS to ±2.5 uA FS.  Measurements employ a 24 bit ADC with programmable resolution from 18 to 24 bits. Each output channel includes SMU output connections, Kelvin (sense) connections, and a driven guard connection for low level current measurements.  


The board is supplied with the GXSMU 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.
