5 Making 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.
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
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.
