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°.

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.
