Test Oscillator
The Test Oscillator generates a static frequency or a sine sweep. The latter is a user-
defined frequency spectrum tone sweep.
Test Oscillator Parameters
 Waveform buttons: Select the type of waveform to be used for test tone generation.
 The Square Wave and Needle Pulse waveforms are available as either aliased or
anti-aliased versions. The latter is used in conjunction with the Anti Aliased button.
 Needle Pulse is a single needle impulse waveform.
 If the Sine Sweep button is active, the fixed oscillator settings in the Waveform
section above are disabled.
 Frequency: Determines the frequency of the oscillator (default is 1 kHz).
 Level: Determines the overall output level of the Test Oscillator.
 Sine Sweep button: Activate to generate a user-defined frequency spectrum sine
wave sweep.
 Time field: Determines the duration of the sweep.
 Start Freq and End Freq fields: Define the oscillator frequency at the beginning and
end of the sine sweep.
 Trigger button: Click to trigger the sine sweep. The behavior of the Trigger button can
be switched via the menu below:
 Single: Clicking the Trigger button triggers the sweep once.
 Continuous: Clicking the Trigger button triggers the sweep indefinitely.
