4.6.2.3 WAVEFORM SYNTHESIS
(Option: Harmonic Analysis and Synthesis)
WAVEFORM SYNTHESIS creates waveforms by using a sine wave series defined by Harmonic
Magnitude and Phase Angle coefficients expressed in polar format (magnitude and phase angle). Each
magnitude percentage is referenced to the fundamental which is always defined as having a magnitude
of 100%.
From any METER display (V/I, AMPS or POWER), press the fn key to enter SETUP MODE.
From the SETUP display, press 2 to enter WAVEFORM SETUP.
From the WAVEFORM SETUP display, press 3 to enter WAVEFORM SYNTHESIS.
The following is displayed if the H.A.S. option is installed.
WAVEFORM SYNTHESIS: WAVEFORM #2
HARMONIC: 2nd
CONTENT:

ANGLE:
NOTE: The CONTENT fields hold the Magnitude values.
The WAVEFORM SYNTHESIS screen is a workspace only and does not display the content of stored
waveforms. The values shown on the screen will be retained from the previous edit.
To create a waveform by Harmonic Synthesis:
a) Specify the Waveform number that will hold the newly created waveform.
b) After entering the Waveform number, ZEROS? will be displayed. Press 0 to zero out any values
presently in that waveform or press enter to continue editing the existing values.
c) Press ENTER to move the cursor to each Magnitude and Phase Angle position. Type the value
for each harmonic. Harmonics up to the 51st may be entered. Press CLEAR to back up to the
previous position. Pressing EDIT will advance the cursor to the next screen set of harmonics.
d) When all desired harmonic data has been entered, either:
a) press the EXECUTE key and any waveform previously stored in the specified
b) Press the STORE key to save the data entered so far, without calculating and
