Phase Between Rising Edges
Measures the phase between two waveforms using the rising edges.
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.
Phase Between Falling Edges
Measures the phase between two waveforms using the falling edges. See
Figure 45 on page 105.
