The softkey PHASE is available after pressing the WAVE MENUS softkey that appears
when outputting dual ac voltages or ac power (shown below for ac power output).

When one output is a harmonic of the other, the phase shift is based on the phase angle
or power factor (cosine) of the harmonic signal. For example, when the AUX output is
generating a 60-Hz signal, and the NORMAL output is generating a 120-Hz (2nd
Harmonic) signal, a phase shift of 60° (pf of .5) would move the AUX signal 60° of
120-Hz (30° of 60 Hz).
4-41. Entering a Phase Angle
Complete the following procedure to enter a phase shift in degrees. This procedure
assumes you have already sourced a dual ac voltage or ac power output.
1. Press the softkey WAVE MENUS, opening the waveform menu.
2. Press the softkey PHASE, opening the phase entry menu.
