I try to measure a single channel voltage and current from my PXIe-4162 SMUs. I had a another program VI to source a channel and set it to a desired voltage I want, but somehow I cannot get the single channel measure to work. It seems really easy but I cannot figure out.
In my measure VI, I do simple stuff:
Initialize with channel -> configure -> initialize -> measure -> close
but I think when I initialize, the voltage I set using another program will be reset and I always measure around zero. I'm not sure what I can configure to avoid resetting the voltage.
Any one with any ideas?
thanks for the reply and this is exactly what I thought... Thanks for confirming this. I made this program as a monitor tool. Program A does the real sourcing. Program B only reads V and I value that is set by program A again at a later time (without changing sourcing set by A).
Program B allows to gain confidence at a later time that after i do something else the current and voltage stays at what I set them, so it's just a debug tool.
Do you know if I'm even capable of doing that? Thanks.
