6.3.5  Configuration of Module RF Signal 

Default Configuration - AGC ON 

The FT5S 

module’s default signal setting is for 77 channels (NTSC) at 75 dBμV per channel. 

If  the  operator  sets,  the  module  to  AGC  mode  when  the  level  changes  within  a  range  of  ±  3  dB  the 

FT5S can still work properly. 

Typical environments:  

 77 channels (NTSC), Broadcast input: 75 dBµV per channel 

 Narrowcast input: 75 dBµV per channel; 

The factory default settings (

DO NOT

 change the values when AGC is ON): 

 Broadcast MGC Value: 0 

 OMI offset: 0 

 Narrowcast MGC: 0 

Custom 

– AGC OFF 

If the input signal is ± 3 dB beyond the range of 75 dBuV, set the AGC mode to off and configure the 

module with the following formula according to the input signal. 

The  narrowcast  channel  configuration  method  is  the  same  as  the  broadcast  method.  Use  the 

broadcast channel as an example; the derivation is as below: 

1.  If BC input signal level is 75 dBµV, the number of channels is N. 

2.  The adjustment level is: 

△

P=75 + 

△

S 

3.  Set  the  BC  MGC  value  to 

△

P,  since  the  range  of  the  MGC  is  -10  dB  to  +5  dB,  if  the  value 

exceeds the range, the

 

OMI offset should be changed (Range: ±3 dB).  

4.  Please refer to the table below for setting the corresponding values of
