Phase
The Oscilloscope mode Phase measures the edge-to-edge phase differences on a single waveform or between two separate waveforms. When the measurement is selected, you can define the waveform, edge number, direction, and threshold used for the measurement start and stop points. FlexDCA counts the waveform edges from the left edge of the display graticule, instead of at the reference point. An annotation label is placed at the start and stop positions.
The measurement can be performed on any single-valued waveform that is displayed in one of a Waveform content windows. The measurement annotation positions are shown in seconds from the reference position. The measurement results are in phase (°).
Upper, lower, and middle threshold levels are defined in the Thresholds tabbed page of the Configure Measurements dialog. The edges you specify must appear on the display graticule.
You must have more than one source available on in order to select the edge of a second waveform as a source for the measurement.
Require FlexDCA version ≥A.04.50.
This measurement is not compatible with PAM4 signals.
