Figure 4-5 Variable phase waveform menu
The variable phase waveform may be configured with the
following parameters.
• Frequency
• Amplitude
• Phase 1
Phase 1 refers to the phase of the selected channel with
reference to channel 1.
Dual sine waveform
The dual sine waveform group allows you to generate a
composite waveform that is the summation of two
independent sine waveforms. Dual sine waveforms are useful
in testing the intermodulation distortion characteristics of an
audio system. To select a dual sine waveform, press
Waveform > Dual Sine.
