R&S SMB Amplitude Modulation - AM
1407.0806.32 4.63 E-2
State - AM
Activates/deactivates AM modulation.
Remote-control command:
SOUR:AM:STAT ON
AM Source - AM
Selects the source for the AM signal.
The source can be selected independently for the different modulation
types and the LF output.
The configuration of the selected external and/or internal modulation
source is performed in the lower section of the menu or in the Mod
Gen block (internal source only).
Int
Selects the internal modulation source for AM
modulation.
Remote-control command:
SOUR:AM:SOUR INT
Ext
Selects the external source. The external signal is
input via the MOD EXT connector.
Remote-control command:
SOUR:AM:SOUR EXT
Int + Ext
Selects the internal and external source at the same
time. This setting enables two-tone AM modulation.
Remote-control command:
SOUR:AM:SOUR INT,EXT
AM Depth
Sets the modulation depth in percent.
Note:
With two-tone modulation please observe that the set modulation
depth is valid for both signals and the sum modulation depth is
determined by doubling the set modulation depth. This results in
overmodulation if the maximal value for modulation depth is
exceeded (see data sheet).
Remote-control command:
SOUR:AM:DEPT 20PCT
