I have the programm on LabView 7.1 which manage the SR830 lock-in amplifier to measure the photocurrent vs bias voltage.
But for my application I need to modify the program which operates in constant current mode, i.e. the photocurrent to be constant by adjusting bias voltage during the measurements.
Does anyone have such program on LABVIEW or know an algorithm to realize this program?
Any help would be greatly appreciated. Thanks in advance for your help.
Hello Geenady, could you solve your issue. Please send your VI that I could check it. What exactly do you want to measure? Could you discribe your situation al little bit more.
