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 12.16.10,
"SOURce:LFOutput Subsystem", on page 837.
For more information:
See Chapter 6.11, "Analog Modulations", on page 346.
12.16.3.1 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.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: 0
Example:
SOURce1:AM1:DEPTh 30
SOURce1:AM1:SOURce LF1
SOURce1:AM1:STATe 1
SOURce1:FM1:DEViation 1000
SOURce1:FM1:STATe 1
// disable both modulation
SOURce1:MODulation:ALL:STATe 0
SOURce1:AM1:STATe?
// 0
SOURce1:FM1:STATe?
// 0
// enable both modulation
SOURce1:MODulation:ALL:STATe 1
SOURce1:AM1:STATe?
// 1
SOURce1:FM1:STATe?
// 1
Manual operation:
See "[Mod on/off]" on page 349
12.16.3.2 SOURce:AM Subsystem
Option: R&S SMBVB-K720
The AM subsystem contains the commands for setting the amplitude modulation and
also the broadband amplitude modulation.
