Acquisition Control 12
Agilent InfiniiVision 3000 X-Series Oscilloscopes User's Guide 195
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.
