Use the horizontal position knob ( ) to pan through the waveform to set the
expanded portion of the normal window around the glitch.
Averaging Acquisition Mode
The Averaging mode lets you average multiple acquisitions together to reduce
noise and increase vertical resolution (at all time/div settings). Averaging requires
a stable trigger.
The number of averages can be set from 2 to 65536 in power-of-2 increments.
A higher number of averages reduces noise more and increases vertical resolution.
The higher the number of averages, the slower the displayed waveform responds
to waveform changes. You must compromise between how quickly the waveform
responds to changes and how much you want to reduce the displayed noise on
the signal.
To use the Averaging mode:
1 Press the [Acquire] key, then press the Acq Mode softkey until the Averaging
mode is selected.
2 Press the #Avgs softkey and turn the Entry knob to set the number of averages
that best eliminates the noise from the displayed waveform. The number of
acquisitions being averaged is displayed in the # Avgs softkey.
