To Output RF Modulated Signal
Requirement
Use the SCPI commands to realize the following functions:
Output an AM modulated signal. Set the carrier frequency to 800 MHz, the carrier amplitude to -20 dBm,
the AM modulation depth to 60% and the modulation frequency to 20 kHz.
Method
1. *IDN? /*Query the ID string of the RF signal generator to check
whether the remote communication is normal*/
2. :SYST:PRES:TYPE FAC /*Set the preset type to "Factory"*/
3. :SYST:PRES /*Restore the instrument to the factory setting (by default,
the modulation source is internal and the modulation
waveform is sine)*/
4. :FREQ 800MHz /*Set the RF carrier frequency to 800 MHz*/
5. :LEV -20 /*Set the RF carrier amplitude to -20 dBm*/
6. :AM:DEPT 60 /*Set the AM modulation depth is 60%*/
7. :AM:FREQ 20kHz /*Set the AM modulation frequency to 20 kHz*/
8. :AM:STAT ON /*Enable the AM function*/
9. :MOD:STAT ON /*Enable the RF modulation output*/
10. :OUTP ON /*Enable the RF output*/
Note: The RF and MOD switches must be turned on.
