e) Disable the signal tracking function:
Press [Frequency] and [Signal Track Off On].
f) Use the maximum holding function to measure the signal drift.
Press [Trace] and [Max Hold].
When the signal changes, the max hold will maintain the maximum response to the input signal.
g) Activate the trace 2 and set it into the continuous clearing and writing mode.
Press [Trace], [Trace 1 2 3] and [Clear Write].
h) Change the output frequency of the signal generator.
Slowly change the output frequency of the signal generator, with the step of 1kHz and the range of ±50kHz. The
spectrum analyzer will display the information shown in Fig. 4-9.
