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 per channel. 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.

Features

The GX3104 employs 18-bit DACs for the sourcing of voltage and current. There are 7 current ranges, ranging from ±2.5 µA FS to ±1 A 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.

Software

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.
