Phase
The Phase function is selected by pressing the FUNCTION PHASE
key.
The Phase mode measures the difference in phase (or time shift)
between two sine or square waves. Both channels must have the same
frequency; phase measurements between two signals of different
frequencies are meaningless (and the reading will wander
continuously).
The upper left corner of the display shows the phase difference. The
units are always degrees.
