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

to 2Vpp*/

7.

:SOUR1:HARM:PHAS 2,30

/*Set the phase of the second order of harmonic of CH1 to

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.

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*/
