4 Making Measurements

Maximum units are in dB and X at Max units are in Hertz for

FFT.

X at Min

X at Min is the X axis value (usually time) at the first displayed

occurrence of the waveform Minimum, starting from the

left-side of the display. For periodic signals, the position of the

minimum may vary throughout the waveform. The X cursor

shows where the current X at Min value is being measured.

Delay and Phase Measurements

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 middle threshold points on the

waveforms. Negative delay values indicate that the selected

edge of source 1 occurred after the selected edge of source 2.

1 Press the Quick Meas&Select and select Delay. 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.

2 Press the Measure Delay softkey to make the measurement.
