3 Use averaging to reduce noise on the displayed waveform.
To use averaging follow these steps.
• Press I Display /, the press the Average softkey.
Notice that
AV appears in the status line.
• Toggle the t Average softkey to select the number of averages that
best eliminates the noise from the displayed waveform.
The
AV initials in the status line indicates how much of the
averaging process is finished,
by turning to inverse video as the
oscilloscope performs
averaging. The higher the number of
averages, the more noise that is removed from the display.
However, the higher the number of averages, the slower the
displayed waveform responds to waveform changes.
You need to
choose between how quickly the waveform responds to changes
and how much noise there is on the signal.
