Delay and Phase Measurements

X at Max
X at Max is the X axis value (usually time) at the first
displayed occurrence of the waveform Maximum, starting
from the left-side of the display. For periodic signals, the
position of the maximum may vary throughout the
waveform. The X cursor shows where the current X at Max
value is being measured.
To measure the peak of an FFT:
1 Select FFT as the math function in the Math menu.
2 Choose Math as the source in the Quick Meas menu.
3 Choose Maximum and X at Max 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.
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.
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
