In the EDIT WAVE Menu, a wave that has either been in use, or a wave
that has been recalled can be edited. Although it is possible to define a new
waveform using the EDIT WAVE menu option, it is not recommended as the
user will have to check harmonics A through O to ensure they are all off.
After entering the PQ Mode and accessing the Wave Selection Menus (explained
previously in this section), complex waveforms can be created and /or modified. To
create a new waveform, press the NEW WAVE blue softkey. Pressing the NEW WAVE
blue softkey will ensure that any previously entered harmonic values will not be present.
The menu shown below appears in the Control Display. This menu allows the user to
specify:
•
any integer harmonic, from the second to the 63rd
•
up to 15 harmonics can be entered, labeled HARMNIC A through HARMNIC O
•
the amplitude of the harmonic, as a percentage of the fundamental
•
the phase of the harmonic relative to the fundamental
Press the HARMNIC A off blue softkey and notice that the off/on display changes to
"on".

Harmonic Number
To specify or edit the harmonic number, press the # HF/F blue softkey and enter the
desired harmonic. For example, press 3 then E to select the 3rd harmonic.
Harmonic Amplitude
Press the AMPL blue softkey to enter the amplitude of the harmonic as a percentage of
the fundamental. For example, press 10 then
E
for 10 %.
Phase
To specify or edit the phase of the harmonic, press the
φ
blue softkey to set the phase.
Continue with the example by entering a phase of 180 degrees.
Following this example, the Control Display will now show the following:
nn335f.eps
To enter another harmonic, press the NEXT HARMNIC blue softkey and repeat the
previous procedure. A maximum of 15 harmonics may be entered. When complete, the
NEXT HARMNIC blue softkey may be pressed repeatedly to examine the contents of
each wave.
Once certain that all values are properly entered, press
P
. The waveform will not take
effect until
P
is pressed. If the calibrator is in Operate Mode, the new waveform will be
re-computed and the calibrator will pause while it builds the composite waveform. If the
calibrator is in Standby Mode, the new waveform will not be built until
O
is pressed.
