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.
3 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.
7 To turn off Quick Meas, press the Quick Meas key again until it
is not illuminated.
Setting measurement thresholds defines the vertical levels
where measurements will be taken on an analog channel.
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.
