Signal Strength vs Signal Quality

mcguyver

whats the difference between these? I have 85% Signal Strength and 100% Signal Quality

RobitTV

i dont know my signal strength is 95% and my quality ia 100% weird

how far is your dish form the tv? Maybe that has something to do with it I have about a 30m run of cable from mine

your signal quality is if it is a stable connection

signal strength is basically the distance from the router

what router?


OP basically a high signal quality shows you are getting a low number of errors over time. The % doesn't matter so much as boxes measure it differently.

This is assuming you are tuned in correctly. It is also useful for working out are you pointed at the right satellite dish. Signal strength could be high and you could be pointed at a random satellite, you would then have no signal quality.

Once you are pointed at the right sat, then you will get strength and quality showing up, you basically care more about quality then, as long as the strength is over say 60% or so on a sky box.

The signal quality is a measure of how few errors your satellite box is getting in the received stream of data. 100% would mean few or no errors and is an indication of how well your dish is pointed at the satellite. It would also mean that during rain or snow conditions your setup is less likely to have outages.
The signal strength is probably a measure of the signal voltage level reaching your satellite box - it's pretty meaningless unless it's measured against a reference. In your case it may be that the 30m of cable is attenuating the signal somewhat and that you would get a higher signal level if you had a shorter run of cable or had a different receiver or....whatever. In any case, once you have a quality level of 100% it can't get any better in the digital domain:)

Thanks for all the info guys

"Signal Quality" is proportional to the inverse of the Bit Error Ratio, calculated by the receiver. You should adjust your dish alignment and LNB distance from the dish for maximum signal strength then adjust the LNB "skew" (rotational position) for maximum "signal quality" indication.
