Vac_fund = fundamental voltage.
F_fund = fundamental frequency.
Vdc = DC voltage component.
Degree = start angle, 0~359.9
°
.
N = Harmonic Number.
V = Harmonic Voltage (Value/Percentage).
Ɵ = phase angle (degrees).
Compose = Value/Percent.

Waveform Preview : press ‘Waveform Preview’ soft key to view the waveform shape. Press the
[Esc] key to cancel the viewer.
Save : to save Synthesis settings to the assigned memory location for quickly recalling at a later
time. If you do not save the current Synthesis settings file, it will be lost after the unit is turned
off.
The waveform synthesis screen is used to create waveforms made up of a series of harmonic
frequencies, amplitudes and phase shifts. Up to 40 order harmonics of 50Hz to 60Hz can be
specified.
1. Synthesis
1. In the ‘Harmonics’ menu press the ‘Synthesis’ soft key.

An OVP error is generated if the output of the synthesized wa DC offset exceeds
424Vpk on the 300V range or 212Vpk on the 150V range.
3. Press the [ESC] key to return to the previous screen then press the ‘Trigger’ soft key to load
the settings.
4. Press the ‘Trigger’ soft key to execute the file, and the ‘Trigger’ soft key will be changed to
‘Stop’.
