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.

The software below is offered as freeware for non-commercial use. For commercial license, please contact me.

FYI, I have never charged anyone to use this software, and probably never will. The licensing terms are primarily intended to prevent eBay equipment sellers from bundling my software with their online sales, which was an obnoxious problem in the early 2010s.

Commercial end-users can expect no-cost license to this software upon request. Except if they are from like Lockheed or Raytheon -- then, I will want a check for $3.50, so I can frame it on my wall. Even then, I can grant you a broad and indefinite probationary license, while you work out how to send me that $3.50 check. You can honestly just hand-pen it on company stationnary -- it's not like I'm going to cash it. But be advised: I won't accept a penny less!

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.
