Why is the Voltage Double the Value I Set on the Function Generator??
One question that comes up a lot from junior engineers when measuring the output of a function/arbitrary waveform generator (FAWG) with a scope or DMM is "why is the measured voltage double the value I set on the FAWG?" The quick answer to that question is there is an impedance mismatch that is causing the discrepancy. Below is a link to a YouTube video created by a colleague of mine that quickly and clearly answers that question.
