3. Press the softkey FUNDMTL to select the 5500A Calibrator front panel terminals
for the fundamental output, either NORMAL or AUX. If sourcing an output on the
5725A Amplifier, the choices are NORMAL or BOOST, where boost is the 5725A
Amplifier terminals. The harmonic appears on the 5500A AUX terminals.
4. Press the softkey HARMNIC to enter the desired harmonic (1 to 50), with a
maximum frequency output of 10 kHz.. For example, entering the 7th harmonic
(below). When the control display shows the desired value, press E .
Harmonic = 1
New harmonic = 7

4-40. Adjusting the Phase
When in the dual ac voltage and ac power output modes, you can set the calibrator to
source two signals with adjustable phase difference. All phase adjustments shift the
AUX waveform in relation to the NORMAL waveform. Phase shift adjustments are
entered into the calibrator either as degrees (0 to ±180.00) or as a power factor (PF). A
leading or positive phase shift will cause the AUX waveform to lead the NORMAL
waveform; a lagging or negative phase shift will cause the AUX waveform to lag the
NORMAL waveform.
