Determine DB levels on Coax Cable

[dwalder]

Guys, I used to work for the cable company many years ago. When I worked there the techs had special meters that were able to determine the DB level for the coax cable. The DB level helped to determine how much "signal" was coming into the customer’s house and into each TV set.

I am currently experiencing problems trying to distribute the modulated signal from a few cameras around the house.

Can anyone tell me if a multimeter (voltmeter) would give some sort of information about how much "signal" or the db levels of a particular cable. I need to determine how much signal the modulator is putting out and other various devices.

Thanks,

Dave

No, you need a real signal meter to actually test for this.


Can you get a capture of the results on screen?

One that we have had people use in the past is the Channel Vision M2000 - RF/Satellite Signal Meter.

what kind of problems you having????

Tri-Porter tester

I haven't used this tester but on the specs sheet it says it has a basic RF meter for cable systems.

all you need is a db reading you have to inject the camera modulation feed at the same level as the cable feed coming into the house or building ... if your new toy gives you db reading you are good to go

there is a rough and ready method for determining signal level using an attenuator (variable).

Add it int he line, increase the attenuation until you lose signal and that is approx the level you have at the TV.
