Signal Generator Window
The test signals created by the signal generator are assigned to a particular
input; this allows you to verify the operation of the processor settings you
have selected.
2. Select the XAP 800 Unit and Input Channel you wish to use.
3. Use the Amplitude control to select the amplitude (volume) of the signal
you wish to use. The amplitude range is from -60 to +20dB. Default is 0dB.
4. Signal Selection
Select Pink (default), White, or Tone for the type of reference audio you
wish the XAP 800 to generate on the selected input.
If you select Pink or White, click Signal On to generate the noise signal.
Click Signal On again to terminate the noise signal.
Pink Noise—An audio test signal containing all the frequencies in a given
audio spectrum, with equal energy in each octave. Pink Noise is the default
signal.
White Noise—An audio test signal which is distributed evenly throughout a
given frequency range.
Tone—Activates the tone configuration portion of the window.
If you select Tone and you wish to use a single tone for reference, select the
frequency of the tone you want generated with the slide control. Or, enter
the frequency in the window next to the Auto Sweep button. The tone is a
sine wave with less than .03% distortion.
5. Click Signal On to generate the tone. Click Signal On again to
terminate the noise signal.
Auto Sweep provides the ability to move the frequency of the tone
generator from a low frequency to a high frequency at a specified rate. To
use this feature, set the Begin Frequency, End Frequency, Increment (of
frequencies sampled), and Rate (of the sweep) in the appropriate fields.
Then click Auto Sweep, which begins the frequency sweep. Note that the
Frequency slide control and readout reflect the progress of the Auto Sweep
function. Click Auto Sweep again to stop the frequency sweep. Auto
Sweep turns off automatically upon completion of the sweep. The sweep
range is 20Hz—20kHz; the increment range is 10Hz—20kHz. The rate range
is 10ms—2000ms. Default is 100ms.
Select the Repeat box if you want Auto Sweep to continue in cycles.
