Hello
I am trying to understand about keithley 2450 smu and smu in general and write a python driver for it
In order to see how it works im connecting it once to a dmm and once to a source meter
The source meter im using is b2902a agilent smu, when im sourcing for example 1.5 v with a limit of 0.8 amper, the voltage that appears on the screen of the source much smaller(less than 1 mv) than what ive set, but on the keithley smu that im measuring with the voltage is 1.5v, what is the voltage that appears on the source?
Ive read that it measures and source at the same time what does it mean? Does it mean that it switches between measure and source ?
Ive done some reading but still don’t fully understand, because I have a few option on the instrument-voltmeter, ammeter, and 4 other measure and source options.
thanks
