Thanks for your note. Let me elaborate a little - My plan is to test the signal at the comcast junction box where the cable run to my home begins, then test the signal where the long cable run hits the grounding block and enters my house, and again at the distribution panel and after the amplifiers, etc., as well as at the room nodes where I'm either experiencing a signal, or not getting one. I just need to learn which signals to test.
It would be great to have a Comcast tech out to do all that, but they don't have the time to troubleshoot my structured wiring setup, and I couldn't afford to pay them if they did.
So, could you give me some tips about which tests to perform that would be most diagnostic, in terms of signal strength and signal quality? I understand that I would need to test several frequencies, but it's not necessary to test them all, is it, in order to determine that I'm getting decent signal strength and quality all the way through the wiring system to a room node?
Anyway, I'd appreciate any tips you or anyone could offer in helping me learn which tests to run.

I have a new cable signal strength meter and I'm hoping to get some advice on its use, since the instructions are sparse and in Chenglish. I have a complex structured video wiring arrangement in my home, and I'm having trouble getting the proper signal to some locations. This new tester can test both digital and analog, and can test signal level by channel (both audio and video), carrier to noise ratio, and mains voltage. It's clear enough on how to make the measurements, but I'm a reasonably technical homeowner rather than a cable tech, so I don't know what to measure. The cable signal goes through several splitters, and amplifiers in some places, and my goal is to measure the signal at different points in order to insure that I'm delivering the proper signal levels at each node.
Is there anyone out there who could offer some tips on what to measure with this meter? I would assume signal level is key, but what about the S/N ratio and mains voltage? What does variation in those tell me? I'd appreciate any help you could provide, thanks.
