Trace Averaging
Averaging is a digital process in which each trace point is
averaged with the previous average value for the same trace
point.
Selecting averaging, when the analyzer is auto- coupled,
changes the detection mode to Sample, smoothing the
displayed noise level.
1 Refer to the first procedure “Reducing Input Attenuation” of
this chapter and follow steps 1, 2 and 3.
2 Turn average on:
Press > Average (On)
3 Set the number of averages to 20:
Press 20,
Since the averaging routine smooths the trace, low level
signals become more visible (see Figure 13).

NOTE
This is a trace processing function and is not the same as using the
average detector (as described on page 41).
