Output Harmonic Wave
Press to display the harmonic user interface. You can set the harmonic output
waveform parameters by operating the harmonic menu on the right side of the
screen.
Harmonic menus include: frequency/period, amplitude/high level, offset/low level,
start phase, harmonic type, harmonic order, sequence number, harmonic amplitude,
harmonic phase.
For the setting frequency/period, amplitude/high level, offset/low level, and starting
phase, please refer to Output Sine Wave on page 10.
Harmonic wave function overview
According to the Fourier transform theory, the time domain waveform is a superposition of a
series of sine waves, expressed by the following equation:
f

Generally, the component of frequency
f
1
is called the fundamental wave,
f
1
is the fundamental
frequency,
A
1
is the fundamental amplitude, and
1
is the fundamental phase. In addition, the
frequency of each component is usually an integer multiple of the fundamental frequency, which
is called harmonic. A component whose frequency is an odd multiple of the fundamental
frequency is called an odd harmonic, and a component whose frequency is an even multiple of
the fundamental frequency is called an even harmonic.
This signal source can output up to 16 harmonic orders. After selecting CH1 or CH2, press the
front panel button to enter the harmonic setting menu. You can set the parameters of
the fundamental, select the type of output harmonics, specify the maximum number of output
harmonics, and the amplitude and phase of each harmonic.
Select the harmonic type
This signal source can output even harmonics, odd harmonics, all harmonics or user-defined
harmonics. Enter the harmonic setting menu and press the harmonic type softkey to select the
desired harmonic type.
