It is not possible to use AM simultaneously with:
●
I/Q modulation,
●
arbitrary waveform generation,
●
digital modulation and
●
digital standards.
The AM modulation depth is limited by the maximum peak envelope power (PEP).
Amplitude Modulation Settings
To open the "Amplitude Modulation" dialog, select "RF/A Mod > Configure > Amplitude
Modulation" or use the MENU key under "RF/A Mod".
In the upper section of the dialog, the modulation source is selected and the modulation
switched on. The modulation 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 dialog or in the "LF Output" dialog (internal source only).
These settings affect all modulations which use the same modulation source.
State
Activates/deactivates AM modulation.
Activation of AM deactivates:
●
I/Q modulation,
●
arbitrary waveform generation,
●
digital modulation and
●
digital standards.
SCPI command:
[:SOURce<hw>]:AM:STATe on page 495
AM Source
Selects the source for the AM signal.
"Internal"
Selects the internal LF generator as the source for AM modulation.
