Signal Generator Window
The signal generator creates test audio signals for sound system
calibration. The test signal is assigned to a particular input, and allows
you to verify the operation of the processor settings you have selected.
Begin by selecting the PSR1212 Unit and Input Channel you wish to
use. Next, 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.
Signal Selection
Next, select Pink (default), White, or Tone for the type of reference
audio you wish the PSR1212 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,
configure the tone generator by selecting 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. Then click Signal On to
generate the tone. Click Signal On again to terminate the noise signal.
If you wish the tone generator to automatically sweep through a
designated frequency range, 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, and 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.
Click Close to return to the G-Ware Configuration window.
