Difference between: Signal Quality Vs Level ?

[URPradhan]

Friends

What is the terms Signal Level and Signal Quality defines properly ?

I'm using 3 different DVB-S applications.

1. progDVB (82,82)
2. MyTheater (78,87)
3. DVB Dream (83,100)

Both the signal level and quality (for same channel) are different with the above 3 different applications respectively (see the figures against the apps)

Can anybody plz explain what are the terms exactly and why they are different with different apps ?

These aps are not calibrated for signal measurement, so just use them for what they are designed, a rough guide.

... then how we can able to know exactly the actual signal level and quality ?
can I trust to SetUpPC the original s/w of Skystar2) ? because I'm using SS2 not any STB receiver.

You cannot measure the exact level, unless you are prepared to invest in a spectrum analyser, or at the least a calibrated satellite signal strength meter.

What you can do is make an fairly accurate comparison, providing you use the same software to measure all satellites.

and sir two queries from my side

1- what is the difference between signal strength and quality.
2- why do two different STBs show different level of signal and strength on the same setup.
