Current-voltage sweep and analysis software

Description

This software works with Keithley 23X and 24XX series source meter units (SMUs) to perform common types of current-voltage characterization of two-terminal devices. It is designed to assist with the typical measurements performed at a probe station in an R&D environment.

Downloads

The software is available as a win32 binary. Self-extracting installers are provided (7-Zip SFX).

• Required libraries:
• NI LabVIEW Runtime Environment 2014 32-bit
• NI 488.2 14.0
• NI Serial Runtime 14.0
• NI VISA Runtime 14.0.1
If the above links go bad, try searching for each library by name. They should be available for free from National Instruments.

• Includes all libraries above.

Requirements

• PC running Windows XP or newer
• The software libraries listed above, or compatible versions thereof, must also be installed.
• Keithley 23X or 24XX series SMU
• I have specifically used the software with models 236, 237, 238, and 2420.
• Supported GPIB or RS232 adapter
• Supported GPIB models include all modern NI adapters (e.g., GPIB-USB-HS, GPIB-USB-B, ...) as well as certain other makes (e.g., Agilent) with appropriate driver software installed.
• Any RS232 adapter that is supported by your Windows version should work, but appropriate drivers must be installed.
• Only 24XX-series instruments have RS232 ports; GPIB is required for 23X instruments.
