Is there a "basics of signal power level" guide for cable TV?

Like http://forums.timewarnercable.com/t5/Connectivity/FYI-basics-of-signal-power-level/td-p/116692 web page. Or is this still valid for cable TV too?

What are you actually looking for?  A way to diagnose the strength of your video service?  You'd need access to a STB/DTA's diagnostic screen.  I am sure there are magic button presses (like cheat codes) that could display that information.  Assuming you could display it, I am not sure we know what to make of the data.

 

I know that the Cisco DTA's that TWC gave out have such a screen / menu system.  Press and hold "7" on your remote to bring it up.  S2N ratios are displayed, and the DTA's status can be GREEN, YELLOW, or RED.  I've seen all three.  I've gotten video while the DTA is in RED status, so take those statuses with a grain of salt.

That's the kind of information I can get displayed on my DTA's.  I don't know how to interpret the information, though, outside of GREEN is good, and RED is bad...

 

It does provide a virtual channel map, which will tell you how linear video is being fed down the pipe in your market.  I am seeing anywhere from 2 to 4 HD feeds on a given 6 MHz channel, with most channels split into 3 streams.
