Thread: SNR AGC BER - What are the recommended levels?


Forum: Dreambox Receivers (all models)

Hi, I'm having some trouble with intermittent freezing of channels, and channels not clearing. I have been trying to find info out whether my signal is too strong or too weak. My SNR is about 94-97%, AGC 40-45 and BER is 0, or very close to 0. Could anyone please point me in the direction of a good explanation of these parameters, and recommended levels for each? Do I need a booster or attenuator, or neither? Apologies if this question has been answered previously - I did try to

    SNR AGC BER - What are the recommended levels?

    Hi,

    I'm having some trouble with intermittent freezing of channels, and channels not clearing. I have been trying to find info out whether my signal is too strong or too weak. My SNR is about 94-97%, AGC 40-45 and BER is 0, or very close to 0.

    Could anyone please point me in the direction of a good explanation of these parameters, and recommended levels for each?

    Do I need a booster or attenuator, or neither?

    Apologies if this question has been answered previously - I did try to search, but I think 3 letter search terms do not work.

    The most important value is BER (BitErrorRate).
    Its not possible to get something better than zero errors.
    It looks like there is a problem with an emu.

    OK - problem sorted.

    I reflashed the image and has similar issues, with blocky channels etc. I finally figured out that it was a problem with the cconnector on the cable connected to the dreambox. I've got the C tuner, with standard crappy coax connectors, not the F-type. I've got F-type everywhere else, but the last connection was coax. A little tweaking has sorted it out.

    In the meantime, I bought a booster today to try out. (will be returned tomorrow!) In any case, i got surprising results.

    The SLX-1 booster from argos, mentioned on many posts here actually dropped the SNR to 80%, even with maximum gain, and the BER rose also!

    Looks like a simple case of a bad connector caused all my grief!
