• I have a question regarding the Keithely 6514 overhead time.

    <p>I want to measure a low-current signal with an electrometer 6514.
    I want to read the current value per second from my computer via GPIB communication.
    Considering the noise, can I set it to 6 nplc and store 5 values in a buffer so that I can read the average value in 1 second?

    1 nplc / 60hz = 16.7ms
    16.7ms * 6 nplc = 100.2 ms
    100.2 ms * 5 buffer = 501 ms...

    I think I need to know the overhead time in addition to the integration time to make the calculation correct, but I can't find any information on the overhead time anywhere.
