Excitation Source
In order to configure the excitation source, click on the Configure Sine Wave Output button in the Module
Configuration window. This brings up a secondary window in which the excitation source is configured. Do not
confuse excitation source with the Source Level column in WaveView’s main window.
Continuous Mode
Continuous mode refers to a continuously running sine
wave of the selected amplitude and frequency. To
configure, select a frequency and amplitude, and then click
“Start.” The selected output will begin and continue
running until the
terminated.
Note: You can save output sine wave configuration files
and open pre-saved files as discussed in the upcoming
section,

Continuous Tab Selected
Sweep Mode
Sweep mode refers to a constant amplitude sine wave that
is being swept in frequency from a selected start frequency
to a selected stop frequency over a selected sweep time
duration. The frequency sweep characteristic can be
chosen to be linear or logarithmic, and is distributed among
1280 discrete steps. The transitions between steps are
continuous in phase and in amplitude.
To configure, make selections for the available parameters,
and then click the
completed, the waveform returns to its start frequency and
is swept again and again until stopped by the user or
WaveView is terminated.
