5-74 Operation
For test purposes, the OnAir 3000 features an internal test signal generator that
is activated from the Chan - Input page (see
the appropriate access rights configured. While the generator is active, the
normal channel buttons in the left part of the page are disabled and displayed
in gray. Waveform, frequency and level settings are performed here.
Notes: Activating the test generator temporarily switches the cannel input from the
assigned source signal to the generator's output. Channel settings, such as EQ,
dynamics, etc. are not affected, which allows setting the channel parameters
to the desired values using the test generator. If no source is routed to the
channel, the test generator works with the default channel settings.
If the channel is currently on-air, the generator can neither be switched on or
off, and the generator buttons are greyed out.
Shape Three buttons allow selecting the desired test waveform: Sine wave, Pink
noise, and White noise.
Level The generator output level is indicated by the blue bar graph; its exact value
is displayed in dB and can be set with the rotary encoder below the field.
Please note that the level setting is exact for the sine wave and pink noise
signals only. The white noise signal level is lower by 8 dB.
If the overall gain is set to 0 dB and the bar graph level meter is configured
to 'VU meter' characteristics, it indicates the generator output level plus the
configured lead (default value: +4 dB) in case of sine wave and pink noise
signals, whereby the pink noise level is somewhat fluctuating around the
adjusted generator level. The white noise signal level is lower by 8 dB.
The dB readings automatically consider the selected amount of headroom
(i.e., 0 dB indication = 0 dB
If Sine wave is selected, the sine wave frequency is displayed in Hz/kHz and
can be set with the rotary encoder below the field.
