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.
The center of the display shows the amplitude of the selected channel.
Pressing the upper center soft key will select among the available units.
The usual absolute and relative amplitude units are available.
