I am trying to know what is the optimal signal strength to be received by an STB in my case the SA 4000DVB. I use the box on Telewest or trying to. I am told that it should be around 0dBmV which is 1mV. Is this true.
If I go into diagnostic mode of the 4000DVB. This is done by removing the power from the rear of the STB and then pressing down the up and down keys togther on the front panel. Now power up the box by inserting the power lead back in and keep holding the up and down keys until the word "diag" appears on the front panel display of the STD. After that let go of the up and down buttons. On page 1 (on your TV), you will see a Receive signal value and it will be in dBmV. What is your signal??

I currently get 10dBV and its highlighted RED. I assume RED means that the signal is too high. I assume that I would need an attenuator. Any ideas. What signal do you receive?
I want to make sure that I understand all the background before I go back to telewest for them to try to solve my problem.
