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: 0.1% 0.0% 0.0% 0.0% 0.0%
Ф
ANGLE: 0.0° 0.0° 0.0° 0.0° 0.0°
The CONTENT fields hold the Magnitude values.
NOTE:
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:
1) Press the
EXECUTE
key and any waveform previously stored in the specified Waveform
location # will be overwritten. All Programs referring to this waveform number are affected
and will immediately use the new waveform.
2) 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.
4.6.3 GENERAL SETUP
GENERAL SETUP is used for system configuration settings as shown below.
From any METER display (V/I, AMPS or POWER), press the
