【Waveform】key and then〖Arb〗key, at last〖Harmonic〗key to enter into the synthesis
window.
(1) Harmonic Times: it defines as the multiple of harmonic frequency to fundamental
frequency, so the parameter should be the positive integer within 50. When
harmonic time set as 1, harmonic frequency is fundamental frequency. It can be set
as practical need, several times or even no fundamental and no order for times.
(2) Harmonic Phase: it defines the phase difference between the start points of
harmonic and fundamental wave with reference to a period 360° of fundamental.
(3) Harmonic Amplitude: it defines the percentage that harmonic amplitude occupied in
the full amplitude range of synthesizer. In limited condition, at a certain point, each
harmonic amplitude adds as full range, so the sum of amplitude should be less than
100%. But practice is different, for same point, different harmonic amplitudes are
possible offset by each other. So the sum of harmonic amplitude maybe larger than
100%. Once the final synthesized waveform get out of the full amplitude, it will
produce the limited amplitude, User should make decision as practical need and
less the amplitude of fundamental or some harmonics; If amplitude set as 0, the
harmonic will be canceled.
Press 〖Harmonic Order〗key to set the three parameters. When complete the setting,
press 〖Execute〗key to synthesize the arbitrary waveform on basis of harmonics and
show it on the window. The more times harmonics you set, the longer time for synthesis
procedure needs.
When power off, the harmonic synthesis data will be lost. So press〖Save〗key to store
this harmonic wave to the “User_harmo” memory in〖Special Wave〗of〖Built-in Wave〗,
which allows to be recalled.
The example shows how to synthesize a arbitrary waveform by fundamental and its 3
harmonics.

(4) Press〖Harmonic Amplitude〗key and set it to be 50.00%.
(5) Press〖Harmonic Order〗key and set it to be 2.
(6) Press〖Harmonic Time〗key and set it to be 3.
(7) Default setting for〖Harmonic Phase〗is 0, no need change.
