4.4.4 Waveform Groups
Waveform groups extend the number of available custom waveform to 200. Each group can
contain up to 50 user-defined waveforms. Groups are numbered 0 through 3 and may be

less than the maximum range value. The voltage range limit is based on the use of a sine wav
with a 1.414 crest factor. A 300 V rms sine wave has a 424 Volt peak voltage. The AC source
has a maximum peak voltage capability that is determined by the selected voltage range. If the
user selects a custom waveform with a crest factor that is higher than 1.414, the peak voltage
would exceed this maximum if the rms voltage were to be programmed at 300 V rms.
The MX Series power source automatically limits the maximum allowable programmed rms
voltage of a any custom waveform by calculating the crest factor of the selected waveform and
controlling the rms limit accordingly. Thus, each custom waveform may have a different
maximum rms value. The 3Pi controller will prevent the user from programming the rms voltage
above this limit. If a value is entered in the
