7700 MultiFrame Manual 

7700ADA7 Analog Video Distribution Amplifier

 

7700ADA7 - 6

 

Revision 1.2.2

 

 

6.4. 

GAIN ADJUSTMENT 

The 

GAIN

  POT on the cards front edge allows the user to adjust the input signal level. Turning the POT 

clockwise will increase the gain. 
 

 

There is enough range on this control to counteract the video level error due to a 
missing or double terminated coaxial connection. This will hide a frequency 
response problem due to the mis-termination.
