5 Making Measurements
If a portion of the waveform required for a measurement
is not displayed or does not display enough resolution to
make the measurement, the result will display “No Edges”,
“Clipped”, “Low Signal”, “< value”, or “> value”, or a
similar message to indicate that the measurement may not
be reliable.

Press the
Clear Meas
softkey to stop making measurements
and to erase the measurement results from the display
line above the softkeys.
When Quick Meas is pressed again, the default
measurements will be Frequency and Peak-Peak.
4 Press the Select softkey then rotate the Entry knob to
select a measurement to be made.
5 The Settings softkey will be available to make additional
measurement settings on some measurements.
6 Press the Measure softkey to make the measurement.

To set measurement thresholds
Setting measurement thresholds defines the vertical levels
where measurements will be taken on an analog channel or
math waveform.
1
Press the
Thresholds
softkey in the
Quick Meas
menu to set
analog channel measurement thresholds.
2
Press the
Source
softkey to select the analog channel or
math waveform source for which you want to change
Changing default thresholds may change measurement results
The default lower, middle, and upper threshold values are 10%, 50%, and 90% of
the value between Top and Base. Changing these threshold definitions from the
default values may change the returned measurement results for Average, Delay,
Duty Cycle, Fall Time, Frequency, Overshoot, Period, Phase, Preshoot, Rise Time,
RMS, +Width, and -Width.
