5 Turn off the signal track function:
Press > Signal Track (Off)
6 Measure the excursion of the signal with maximum hold:
Press > Max Hold
As the signal varies, maximum hold maintains the maximum
responses of the input signal. Annotation on the left side of
the screen indicates the trace mode. For example, M1 S2 S3
S4, indicates trace 1 is in maximum- hold mode, trace 2, trace
3, and trace 4 are in store- blank mode.
7 Activate trace 2 and change the mode to continuous sweep:
Press > Select Trace > Trace 2
Press Clear Write
Trace 1 remains in maximum hold mode to show any drift
in the signal.
8 Slowly increase the frequency of the signal generator. Your
analyzer display should look similar to Figure 15.
