Making Delay and Phase Measurements
Digital channel measurements
Automatic measurements Phase 1
channels on the mixed-signal oscilloscope. Both analog channel 1 and channel 2
must be turned on for these phase and delay measurements.
Delay 1 2
Delay 1 2 measures the time difference from the rising edges of channel 1 and
channel 2 that are closest to the trigger reference point at the 50% points on
the waveforms. Negative delay values indicate that the rising edge of channel
1 occurred after the rising edge of channel 2. The measurement source must
be set to channel 1.
Channel 1
Channel 2
Phase 1 2
Phase 1 2 is the calculated phase shift from channel 1 to channel 2, expressed
in degrees. Negative phase shift values indicate that the rising edge of channel
1 occurred after the rising edge of channel 2. The measurement source must
be set to channel 1.
