Program for the Keithley 2450 as a fast arbitrary current waveform player

[justanothername]

Hi everybody.
I wanted to share with you a project I worked on the last weekends. For those who own a Keithley 2450 SMU, with this you can use it to play arbitrary current waveform. I use it to compare LT-Spice battery models with the reality.
The features are:

• A nice GUI with all necessary settings, logging and plotting of the results
• Sources current and measures voltage
• The waveform is loaded from a LT-Spice style PWL text file, so you can compare your measurements with your simulation
• Timing is accurately done by the SMU internally
• Generates the trigger model and trigger timer. Loads the data points as config list into the SMU.
• Undervoltage lockout (UVLO) optionally included into the trigger model
• Ability to calculate NPLC (number of power line cycles) automatically based on the desired time step
• Full program configuration can be saved and loaded with .ini files
• Export results to .csv
• Extensive logging and failure detection
• Nice beep sounds (optional)
