5 Measurements and Math Functions

Maximum units are in dB and X at Max Y units are in Hertz for FFT.
X at Min Y
X at Min Y 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
Y 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 [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.
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 on.
