Figure 4-8. Using Marker Tracking to Track an Unstable Signal
The spectrum analyzer can measure the short- and long-term stability of a
source. The maximum amplitude level and the frequency drift of an input
signal trace can be displayed and held by using the maximum-hold function.
The minimum amplitude level can be displayed by using minimum hold
(available for trace C only).
You can use the maximum-hold and minimum-hold functions if, for example,
you want to determine how much of the frequency spectrum an FM signal
occupies.
