2.8 To Set Harmonic Function
The SDG2000X can be used as a harmonic generator to output harmonics
with specified order, amplitude and phase. According to the Fourier transform,
a periodic time domain waveform is the superposition of a series of sine
waveforms as shown in the equation below:
Generally, the component with f
1
frequency is called fundamental waveform, f
1
is fundamental waveform frequency, A
1
is fundamental waveform amplitude,
and φ
1
is fundamental waveform phase. The frequencies of the other
components (called harmonics) are all integral multiples of the fundamental
waveform. Components whose frequencies are odd multiples of the
fundamental waveform frequency are called odd harmonics and components
whose frequencies are even multiples of the fundamental waveform frequency
are called even harmonics.
Press Waveforms → Sine → Harmonic and choose ―On‖, then press
Harmonic Parameter to enter the following interface.
