Characteristics and use
The Pink Noise test signal has a high spectral density, an infinite
period (> 100 years) and 20 kHz bandwidth. Pink Noise is used
as a reference signal for the layout of loudspeaker systems
(PA systems), whereby a Real Time Analyzer (RTA) is used to
execute the required measurements.
When operated in the intermittent mode, Pink Noise forms the
basis for reverberation time measurements.
Operation
You can choose between the following test signal modes with
the MOD setting
1 :
CONT Generates a continuous test signal.
Generates an intermittent test signal.
You can determine the cycle times of the inter-
mittent signal with the CYC setting
2 .
(3/3 = 3 seconds of signal and 3 seconds pause.)
These settings have no effect in the continuous
mode.
