Dear all,
I am a beginner on Labview. I am trying to write my first .vi to sweep I-V curve using Keithley 2450.
I have some confusions about how to read the buffer of 2450 after the measurement finishing.
My question is: What does the buffer consist of? For example, if I source Voltage and measure the current, then there might be both voltage value and current value at least in the buffer. So, how can I separate the different values when I excute read buffer SCPI commands?
I have consulted the reference mannual provided by Keithley. It uses TRAC:DATA? 1, 21, "defbuffer1", SOUR, READ. But I am still confusing about the exact buffer formates.
Thanks for any reply.
Sincerely,
John

I recommend you just use the LabVIEW driver for your instrument. There is a Fetch function which does it all for you.
