13.16.3 Analog modulation subsystems
Option: see Chapter 7.11, "Analog modulations" , on page 357.
The subsystems in this section describe all commands for analog modulation of the RF
signal. Divided in separate sections, you can configure amplitude modulation (AM), fre-
quency modulation (FM) , phase modulation (PhiM) and pulse modulation (PULM).
You can perform each of the modulations either with an internally generated modula-
tion signal or with an externally applied signal.
To configure the internal signal, use the commands listed in Chapter 13.16.10,
"SOURce:LFOutput subsystem" , on page 902.
For more information:

13.16.3.1 SOURce:MODulation subsystem
The command in this subsytem allows you to disable all active modulations at once,
and, vice versa, to restore the last active ones.
[:SOURce<hw>]:MODulation[:ALL][:STATe] <State>
Activates all modulations that were active before the last switching off.
