To Output RF signal
Requirement
Use the SCPI commands to realize the following functions:
Output a RF signal with 1 GHz frequency and -40 dBm amplitude from the [RF OUTPUT 50Ω] connector.
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*/
4. :FREQ 1GHz /*Set the RF signal frequency to 1 GHz*/
5. :LEV -40 /* Set the RF signal amplitude to -40 dBm*/
6. :OUTP ON /*Enable the RF output*/
To Output RF Sweep Signal
Requirement
Use the SCPI commands to realize the following functions:
Output a RF sweep signal from the [RF OUTPUT 50Ω] connector by configuring continuous linear step
sweep. Set the frequency range to 1 GHz to 2 GHz, the amplitude range to -20 dBm to 0 dBm, the number
of sweep points to 10 and the dwell time to 500 ms.
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
sweep mode is continuous, the sweep type is step and the
sweep spacing is linear)*/
4. :SWE:STEP:STAR:FREQ 1GHz /*Set the start frequency of step sweep to 1 GHz*/
5. :SWE:STEP:STOP:FREQ 2GHz /*Set the stop frequency of step sweep to 2 GHz*/
6. :SWE:STEP:STAR:LEV -20 /*Set the start level of step sweep to 20 dBm*/
7. :SWE:STEP:STOP:LEV 0 /*Set the stop level of step sweep to 0 dBm*/
8. :SWE:STEP:POIN 10 /*Set the number of step sweep points to 10*/
9. :SWE:STEP:DWEL 500ms /*Set the dwell time of step sweep to 500ms*/
10. :SWE:STAT LEV,FREQ /*Enable the frequency and amplitude sweep functions at the
same*/
11. :OUTP ON /*Enable the RF output*/
