Using in Scope Mode 5 - 11
Smoothing the Waveform (Average)
The test tool can average multiple samples of a waveform,
allowing for noise suppression without loss of bandwidth.
To select average in the Scope mode, do the following:
1. From the More Scope window, highlight AVERAGE
WAVEFORMS.
2. Press to open the list box.
3. Use to choose the number of waveforms to
average for each display update. The maximum
number is 256.
4. Press to select.
5. Press (CLOSE) to close the window.
To turn off averaging, set AVERAGE WAVEFORMS to be
off again.
NOTE
AVERAGE WAVEFORMS: OFF changes to AVERAGE
WAVEFORMS: by 4 in the 10 mV and 20 mV attenuator
ranges when a 10:1 probe is used.
Additional information about smoothing appears in Chapter 6.
Waveform samples with and without averaging are shown
in Figure 5-9.
