The following figure shows a typical sine waveform and its
configurable parameters.
Figure 4-4 Typ i cal s ine w ave f orm and parameters
Based on the above figure, Vpeak is equivalent to 1.0 V. Vpp
is equivalent to 2 V. The DC offset has a value of 1.5 V. This
value is equivalent to the average amplitude of the
waveform.
Variable phase waveform
The variable phase mode 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. To select the variable phase
waveform, press Waveform > Variable Phase.
