Auto measurement
Use the Auto All function to determine the required measurement parameters automat-
ically.
The following settings are determined:
●
Modulation depth

Marker 1 / Marker 2 / Marker 3
Indicates the detected characteristic values as determined by the AM Modulation
Depth measurement:
Marker Description
M1 Maximum of the signal (= carrier level)
D2 Offset of next peak to the right of the carrier
D3 Offset of the next peak to the left of the carrier
The marker positions can be edited; the modulation depth is then recalculated accord-
ing to the new marker values.
To reset all marker positions automatically, use the Search Signals function.
Note: Moving the marker positions manually. When the position of delta marker 2 is
changed, delta marker 3 is moved symmetrically with respect to the reference marker
1.
Delta marker 3, on the other hand, can be moved for fine adjustment independently of
marker 2.
Marker 1 can also be moved manually for re-adjustment without affecting the position
of the delta markers.

Search Signals
Performs a new search on the input signal and recalculates the AM Modulation Depth
according to the measured values.
