I can't remember which way the figure should be for Line Noise and noise attenuation.
Should line Noise be a higher figure than Attenuation or the other way.

Eg

Line Noise - 18.3db
Noise Attenuation - 27db

or

Line Noise - 27.2db
Noise Attenuation - 18db

thanks

Line noise and margin are similar items, the margin just being the difference between the required noise and yours...This should be as high as possible for a more stable connection. IIRC, you need about 10db margin to keep your current sync rate.

Line attenuation is similar to loss. This should be as low as possible..
