Peak Detection mechanism

As shown in Figure No 8 there is a colored indicator of the peak detection mechanism, for each output transport 

stream. This indicates if any overflow has occurred on modulator’s output bitrate with the following colors:

• 

Green

  

–   No overflow occurred

• 

Yellow

  

–   No overflow occurred but the input bitrate is close to the output bitrate

• 

Red

  

–   Overflow occurred. The user must decrease the input bitrate

4.2.7 - “Output” page

At the “RF Output” page the user is able to select in which modulation standard the four (4) output modulator will 

operate (Figure No10).

DVB-T:   4 x modulator working in DVB-T standard 

DVB-C:  4 x modulator working in DVB-C standard
