Variable phase waveform
Variable phase waveform outputs a sine waveform on all channels. The waveforms on all
channels share the same frequency; however their phase and amplitude can differ. Variable
phase waveforms are useful for measuring the phase difference or timing skew between the
channels of a multiple channel audio system. Variable phase waveform outputs a sine
waveform at the selected frequency at both channel outputs with the channel 2 output
phase varies from –180° to +179.99°, relative to the channel 1 output.
Variable phase waveform mode is applicable for the analog, digital, and Bluetooth
generator. The waveform configuration for variable phase waveform is displayed as shown
in Figure 3-7, Figure 3-8, and Figure 3-8 for the analog, digital, and Bluetooth generator
respectively.
