To Output Harmonic Waveform
Requirement
Use the SCPI commands to realize the following functions:
Output harmonic waveform from the output connector of CH1 at the front panel; the fundamental
waveform (sine) parameters are 1kHz frequency, 5Vpp amplitude, 0V
DC
offset voltage and 0° start phase;
set the highest order of harmonic to 4, the harmonic type to even, the amplitude and phase of the second
order of harmonic to 2Vpp and 30°, the amplitude and phase of the forth order of harmonic to 1Vpp and
50°.
Method
1. *IDN? /*Query the ID string of the signal generator to check
whether the remote communication is normal*/
2. :SOUR1:APPL:SIN 1000,5,0,0 /*Set the waveform of CH1 to sine, the frequency to 1kHz,
the amplitude to 5Vpp, the offset to 0V
DC
and the start
phase to 0°*/
3. :SOUR1:HARM ON /*Turn on the harmonic function of CH1*/
4. :SOUR1:HARM:ORDE 4 /*Set the highest order of harmonic of CH1 to 4*/
5. :SOUR1:HARM:TYP EVEN /*Set the harmonic type of harmonic of CH1 to even*/
6. :SOUR1:HARM:AMPL 2,2 /*Set the amplitude of the second order of harmonic of CH1

30°*/
8. :SOUR1:HARM:AMPL 4,1 /*Set the amplitude of the forth order of harmonic of CH1 to
1Vpp*/
9. :SOUR1:HARM:PHAS 4,50 /*Set the phase of the forth order of harmonic of CH1 to
50°*/
10. :OUTP1 ON /*Turn on the output of CH1*/
To Output AM Modulated Waveform
Requirement
Use the SCPI commands to realize the following functions:
Output AM modulated waveform from the output connector of CH1 at the front panel; set the carrier
waveform to sine (1kHz frequency, 5Vpp amplitude, 0V
DC
offset voltage and 0° start phase); select internal
modulation source; set the modulating waveform to sine, the modulation depth to 80% and the modulation
frequency to 200Hz; turn on the carrier waveform suppression function.
