Digital channel measurements

Automatic measurements Phase, and Delay are not valid for digital channels on the mixed-signal oscilloscope or for the math FFT function. The two sources defined in the phase and delay measurement must be turned.

Delay

Delay measures the time difference from the selected edge on source 1 and the selected edge on source 2 closest to the trigger reference point at the 50% points on the waveforms. Negative delay values indicate that the selected edge of source 1 occurred after the selected edge of source 2.

Source 1

Delay

Source 2

•Press the Settings softkey to select the source channels and slope for the delay measurement.

The default Delay settings measure from the rising edge of channel 1 to the rising edge of channel 2.

The example below shows a delay measurement between the rising edge of channel 1 and the falling edge of channel 2.
