Phase Measurements
Making a phase measurement is done by first setting a reference for the full
360 degree waveform period. Use the following procedure as a guide:
1. Apply the reference waveform to the CH 1 input connector (any channel
may be used, but CH 1 and CH 2 provide the most signal scaling possi
bilities) . Use the standard 10X attenuator probe supplied with the instru
ment to make the signal connections as they produce very little signal
loading to a circuit under test and produce matched delays. For phase
measurements, external loading of a circuit and different delays in the
signal connection paths will produce incorrect results.
