Signal generator 

The signal generator is needed to transmit test signals and the screen 
view from the MSK 33 during "Comfortable Up/Downstream 
measurement" (see system description). In addition to an internal test 
picture of coloured bars it has an external modulation input 
(CVBS/RGB + sound) and is double-sideband modulated. 

The channels/frequencies and levels can be selected freely. 

Only use the signal generator on free channels so that 
programmes and services in the cable network are not 
interrupted. Please use the operating concept on page 2 for help 
with understanding the operating sequence.
