Parameter-variable waveforms The desired waveform can be quickly generated

NF has incorporated an innovative waveform library called a parameter-variable waveform function.
The parameter-variable waveform offers an easy-order waveform system. The appropriate waveform for your purpose can be generated easily: just select a preprogrammed waveform and edit it using parameters specific to your requirements. The 25 types of available waveforms include circuit-related, communication-related, and machine-related waveforms.

Names and variable paramters of preprogrammed waveforms (25 types)
1. Unbalanced sine 2. Clipped sine 3. CF controlled sine 4. Conduction angle

For example....
The CF (crest factor) can be set within a range from 1.41 to 10.00 and varied easily using the modify knob.
Waveforms generated in this way can be treated as standard waveforms with respect to frequency, amplitude, oscillation mode and other parameters.
