Chapter XV Waveform Generator (Option)
The 4456 series provides single-channel waveform generator hardware option, which can output standard
waveforms such as Sine, Square and Ramp, as well as generates a number of modulation waveforms such as
amplitude modulation, frequency modulation and key control. More importantly, it can generate any waveform
edited by users and provide a number of built-in waveforms.

key in the Function Area on the front panel, and open WaveGen menu (if no waveform
generator hardware option is purchased, the corresponding prompt information will be given). For different
waveform types, the WaveGen menu will be adjusted accordingly. The corresponding menus of different
waveforms are slightly different, as shown in the description of waveform types.
