RF levels from a cable modem ? - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I have a copy of a modem test. It is just the RF testing results from a modem test. You can see the SND results with a value of 34.1. The DS stands for downstream. I found a lot of sites where they explain SINAD measurements but I don't know how to interpret those SND results in a modem test?
