    Simple DVM RMS == Orcad Trace RMS

    Dear all
    does measuing the RMS using a very simple DVM (using AC Measuring ) for a pulse signal ( 555 Osc. o/p) will give the same result using the RMS() trace funcation in orcad ??

    in other words does simple DVM RMS === Orcad Trace RMS

    thanks all
    bye

    Unlikely. A simulation measurement will be a 'true RMS'. A simple multimeter will do a simple average and then correct the value assuming it was a sine wave. If it wasn't a sine wave the answer will be incorrect.
