    Question explanation wanted please


    BER,,,bit error rate,,,what does this relate too?,,,what causes it and how to fix?

    too many factors can cause it. how to fix? it is done automatically since the errant packet is again requested for re-transmission if not corrected in the process of receiving it.

    and you will use something like this to test for BER.

    well I dont have as much detail as sir Boknoy,
    but on our ****** encrypted decoders we are always looking for
    the highest BER, which will give you a dead clear high signal,
    mostly used on the Pace Decoders.
    the same applies when we use the Sat signal strength meters, we
    do look for the highest BER.
    Still I too need an explanation in comparison to BER and Signal quality.
    The question; is the higher the BER the Higher the Quality reception.
    I could read, but discussions makes better understanding.

    The higher the BER, the greater the receiver/decoder's ability to perform well during marginal reception conditions, such as when there is heavy rainfall, snow or wind gusts.

    thnx for the replies,,
    @bro boknoy,i am always trying to fill in gaps in my sat knowledge.the links u posted are informative.

    ok,,so am i correct in assuming the a ber value of 0 is the optimum result ,as this means it is receiving the signal and not having to correct any error?,,,the higher the value shown is indication the stb having to recieve duplicate packets ?

    does a high ber figure indicate misalignment ?
    if so,what element is it most relevant to,,,dish position,focal length,offset degree of lnb?or all of these ?
    i understand that this is different to the stb's abilty to process the ber and the speed at which it can do it.

    @ bro cogil,if my understanding on this is correct,,u should be trying to get the lowest values on ur instals ,,not the highest.

    im not sure if all receivers process the error at the same speed or if better quality stb's can process the amount or speed differently.maybe some members can enlighten me.
    cheers,,,dave

    yes, thats correct and certainly for the dm500(manual p.33)

    and yes it indicates misalignment. u will notice a difference if u misalign ur dish on purpose by moving it slightly.
    i dont know which is most relevant to,,,dish position,focal length,offset degree of lnb?or all of these.
    but a google must give u some options

    BER

    Does not mean your dish is not align

    It maybe possible to reduce the BER by moving your dish lft,rgt,up,down

    There are many number of reasons for BER present

    BER - Encoding and more to do with the electronics of your receiver

    A solid dish will reduce the BER

    You may also have BER becuase your BOX is a clone ?

    We dont want everyone playing with there dish thinking its out of alignment do we ?

    Dont get confused about BER

    as i have mentioned, there simply are too many factors in a BER reading. but eliminating them one at a time as has been outlined above can help in clarity of reception. you can only maximise what is thrown at you, other than that, there is nothing else to do.

    now am getting more confused than when i started, with the pace dsd 610 and the sat meters, though not ready for the reading or refs right now;
