13.16.1 Analog Modulation Subsystems
Option: see Chapter 4.1, "Required Options", on page 73.
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 13.16.6,
"SOURce:LFOutput Subsystem", on page 599.
For more information:
See Chapter 4, "Analog Modulations", on page 73.
13.16.1.1 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
