3.6.2.2 Using Markers and Delta Markers
The markers are used for marking points on traces, reading out measurement results
and for selecting a display area quickly.
Marker Search Functions, Restricting the Search Range
The following example is based on an AM-modulated signal at 100 MHz that has the
following characteristics:
Carrier signal level -30 dBm
AF frequency 100 kHz
Modulation depth 50 %
Marker 1 and then delta marker 2 are set to the largest maximum points on the trace.
The frequency and level are then read. In the following measurements, the instru-
ment's default setting can be used for measurements (SetupInstrument).
