Measuring Cable signal strength
 
I have recently installed a couple of CATV outlet points for NTL cable
around the house terminating in F sockets.
These connect to the brown box on the front of the house using a splitter
supplied by NTL.
I am having problems with one of the connections where I don`t think the
signal strength is good enough, the run is approx 10m using proper sat
cable.
Is there any way to measure the signal strength using a multimeter or
otherwise to determine if it is strong enough and what it should be ?
Thanks
Steve

If this relates to cable broadband, have a look he

Don't see how you could measure it with a multimeter...

Well, it should be good for much greater distances than that. Are you
usig a router or just a splitter ?

Really you need the former.

If you have made your own cables up, you might not have made one of the
connections very well

What TV box do you have?
If it's a Pace one, do the following...

turn the box off at the wall (or unplug the power cable at the back)
Turn the TV on, and tune into the correct channel (or if it auto switches
via SCAT, just turn the TV on!)
Hold the up and down buttons on the front of the box and wait until you get
into the engineers screen
now use the left and right buttons to get to page 12 (This should be DVB
DEMOD Status - of not, find that page, as it may be a different number on
different models!)
You should have three green boxes - The SNR box is the all important one!
Compare the readings to that of a known good socket (Mine is green and on
32.5dB)

Hope this helps!
