12.15.1.2 SOURce:AM subsystem
Option: R&S SMBB-K720
The AM subsystem contains the commands for setting the amplitude modulation and
also the broadband amplitude modulation.
The following examples show some variants for generating AM signals.
Example: Creating an amplitude modulated RF signal
Using the internal LF generator, the following command sequence configures an ampli-
tude modulated signal.
// Reset the instrument to start from a defined state
*RST
// Set RF frequency and amplitude
SOURce1:FREQuency:CW 6000000000
SOURce1:POWer:LEVel:IMMediate:AMPLitude -25
// Configure the modulation signal
SOURce1:LFOutput1:SHAPe SINE
SOURce1:LFOutput1:FREQuency 20000
// Configure the amplitude modulation settings and switch AM on
