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 3rd 4th 5th 6th
CONTENT: .1% 0% 0% 0% 0%
Φ
ANGLE: 0º 0º 0º 0º 0º
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
Waveform location # will be overwritten. All Programs referring to this waveform # are
affected and will immediately use the new waveform.
b) Press the
STORE
key to save the data entered so far, without calculating and
producing the new waveform. The display will return to standard metering. The
waveform will continue to use the old content. The new values are saved in the
WAVEFORM SYNTHESIS screen and may be further edited or EXECUTED later.
