Phase
Phase is the calculated phase shift from source 1 to source
2, expressed in degrees. Negative phase shift values indicate
that the rising edge of source 1 occurred after the rising
edge of source 2.
1 Press the Settings softkey to select the source 1 and
source 2 channels for the phase measurement.
The default Phase settings measure from channel 1 to
channel 2.
The example below shows a phase measurement between the
channel 1 and the math d/dt function on channel 1.
