SOURce1:LFOutput1:STATe 1
OUTPut1:STATe 1
Example: Using an external signal source
Using an external signal source, you can additionally determine whether you want to
use only the AC component of the external modulation signal.
// Reset the instrument to start from a defined state
*RST
// Set frequency and amplitude
SOURce1:FREQuency:CW 6000000000
SOURce1:POWer:LEVel:IMMediate:AMPLitude -25
// Configure the amplitude modulation settings and switch AM on
SOURce1:AM1:SOURce EXT1
SOURce1:AM1:DEPTh 40
// Query the input sensitivity at the external modulation input
SOURCe1:AM1:SENSitivity?
// Response: 40
// Since the voltage value for full modulation is 1V,
// the resulting sensitivity is precisely 50%/V.
// This value is assigned to the voltage value for full
// modulation of the input.
// select the coupling mode AC for external amplitude modulation
SOURce1:INPut:MODext:COUPling1 AC
// Switch on AM and RF signal output
