Can I use this unit to check the signal strength and signal to noise ratios of my Comcast Cable? I don't want to spend hundreds for a pro meter.

I don't believe so. This unit is for over the air signals while pointing the antenna in a RV for the strongest signal.

It should, but I have never used it like that. Please note that when I reviewed this model it was designed for motor homes.

I seem to remember there being an adjustment for syncing.. The thing worked very well for me hooking up a base model comcast cable box. At one point I had an out of sync problem, but rebooting this box fixed it.. Never had it happen since.

It has coaxial testers but i never used them because i didn't work with coax at the time. It only tested cat3/5/6 for about 2 weeks before it broke

Im not sure if this would be best for that, I was tracking cable lines through my house. The best way to use this is if the attach the base to one end and then use the pen to trace the wire. It doesn't really tell you how good the connection is.

Yes, this will help if you have a low signal level getting to your modem. If you don't have too low a signal level then it will do nothing useful. In other words if your signal is lower than about (negative) -13dBmV this may help. If it's higher it won't.

NO. And I suspect you will not find anything except some extremely expensive pro engineering test equipment that will. The ATSC signal is quite complex.

The does not have a coax input. So, if Comcast uses cable connections (rather than phone line hookups), I don't think this will work. I used it with AT&T; DSL, because they provide their signal (in the house) via phone lines and/or ethernet cables. Hope that helps. :)

Yes. It will measure and calculate cost of only the electricity passing through the sensors. For example it could measure only the power used by an air conditioning unit if it was mounted on the wires going only to the AC unit. Power used by the rest of the house would not be measured.

Yes. Keep in mind that it's not an advanced tester. It only tests the pins in sequence to see if each wire is connecting. If a light doesn't show, you have a bad cable. It doesn't test things like capacitance, attenuation, crosstalk, and the like.

I bought one for the same reason - to save the $8/month to Comcast. After many hours and many calls, a tech (not Comcast!), told me that it would never work properly for all three functions - cable, phone & internet. He said their modems have some firmware that is proprietary but they will delight it. Long story short: pay Comcast the $8 and "Enjoy" it!

The reasons that I'm asking is 1) I'm new to using digital multimeters and I'm looking for one to use as a tool for checking bad capicators on computer motherboards.

Why would you have to inject a signal into the cable if the network tester is doing the same thing? If you cut the cable in two you could inject a signal, but what would be the point?

The Motorola signal booster I purchased did nothing to improve the signal strength of my system (although I was looking for a better cable TV signal) and it knocked out my internet signal. For my system it was a waste of time and money (I have Comcast as an internet / TV / Phone provider) your situation may be different.

No, it is not. It is able to tell you if there is PoE on the line and what speed the port is, but that is all.

Not even sure what a kind of meter that is. Sorry. I will say you will be better off buying one of the better ( Higher priced) units. You can hook the sensors right on the wires inside the circuit box in the house. This one is cheap junk with no support and are not even sold by B&D; anymore.

I'm not sure it matters, as long as you have a USB port to power the sensor. If you can find your cable box sensor by covering it up with your thumb, then that's where you tape down the the signal repeater

I purchased one some time back and wanted to use it to replace my cable box. It did no do that so I assume that it can not do what you want it to do.It is a very technical piece of equipment and not for a casual user.
