Test Oscillator
Test Oscillator generates a static frequency or a sine sweep. The latter is a user-defined
frequency spectrum tone sweep. The Test Oscillator is useful for tuning studio equipment
and instruments.
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 when 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
are disabled.
Frequency knob and field: Determines the frequency of the oscillator (default is 1 kHz).
Sine Sweep button: Generates a sine wave sweep (of the frequency spectrum you set
with the Start Freq and End Freq fields).
Time field: Sets the duration of the sine wave sweep.
Start Freq and End Freq fields: Drag vertically to define the oscillator frequency at the
beginning and end of the sine sweep.
Trigger button and pop-up menu: Click the Trigger button to trigger the sine sweep.
Choose the behavior of the Trigger button from the pop-up menu:
Single: Triggers the sweep once.
Continuous: Triggers the sweep indefinitely.
Level slider and field: Determines the overall output level of the Test Oscillator.
