Phase and Delay
Phase
Phase is the calculated phase shift from input source 1 to input source 2,
expressed in degrees. Negative phase shift values indicate that the rising
edge of source 1 occur after the rising edge of source 2.

Delay
Delay is defined as the difference between the selected edge on source 1
and the selected edge on source 2, closest trigger reference point being the
middle threshold points on the waveforms. Negative delay indicates that
the selected edge of source 1 occur after the selected edge of source 2.
