Noise generator
The noise generator is used for measuring cable installations or
sections of cable installations that are not yet occupied with
programming.
It generates a broadband noise to evaluate the frequency response in
the range from 4 MHz to 1 GHz. The bandwidth can be set to 1 MHz
or 7/8 MHz.
Do not use the noise generator if programmes or services are fed
into the cable network and/or if subscribers are connected!
Please use the operating concept on page 2 for help with
understanding the operating sequence.
