To Output Harmonic
Requirement
Use the SCPI commands to realize the following functions:
Output harmonic waveform from the front panel output connector of CH1; the fundamental waveform (Sine)
parameters are 1 kHz frequency, 5 Vpp amplitude, 0 Vdc 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 2 Vpp and 30°, the amplitude and phase of the fourth order of harmonic to 1 Vpp and 50°.
Method
/*Queries the ID string of the signal generator to test
whether the remote communication works normally.*/
:SOUR1:APPL:SIN 1000,5,0,0
/*Sets the waveform of CH1 to Sine with 1kHz frequency, 5
Vpp amplitude, 0V
dc
offset, and 0° start phase.*/
/*Enables the harmonic function of CH1.*/
/*Sets the highest order of harmonic that CH1 can output to
4.*/
/*Sets the harmonic type of CH1 to odd harmonic.*/
/*Sets the amplitude of the second order of harmonic of CH1
to 2 Vpp.*/
/*Sets the phase of the second order of harmonic of CH1 to
30°.*/
/*Sets the amplitude of the fourth order of harmonic of CH1
to 1 Vpp.*/
/*Sets the phase of the fourth order of harmonic of CH1 to
50°.*/
/*Enables 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 front-panel output connector of CH1; set the carrier waveform to
Sine (1 kHz frequency, 5 Vpp amplitude, 0 Vdc 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 200 Hz; enable the carrier waveform suppression function.
