Truncated Sine Wave
When the wave selection is truncs, a truncated sine wave current or voltage signal is
present on the calibrator outputs (Figure 4-14). The variables for the truncated sine wave
are amplitude and frequency. Whenever a truncated sine wave is selected, the Output
Display indicates amplitudes in p-p units.

How to Set Harmonics
When the calibrator is outputting dual ac voltages or ac power (sine waves only), the
calibrator sources two signals with adjustable harmonic difference, with a maximum
harmonic frequency output of 10 kHz. For example, a 120 V, 60 Hz signal can be set on
the front panel NORMAL terminals, and a 1 V, 300 Hz (5th harmonic) output on the
AUX terminals. The fundamental can be configured on either the NORMAL or the AUX
terminals, with the harmonic output on the opposite terminals. Note that the maximum
AUX output is 3.3 V, while the maximum NORMAL output is 1000 V. Unless both the
fundamental and harmonic frequencies are allowed for the given amplitude, the output is
not allowed.
Complete the following procedure to enter a harmonic output. 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 HARMONIC MENUS, opening the harmonic submenu (below is
typical).
