Guest Posted September 19, 2005 Share Posted September 19, 2005 Good advice, but the earth loop problem is more indepth and if you get a good one like the one we have been on for three days, you start pulling your hair out 68368[/snapback] if possible just isolate the camera from ground (unless it is 230V camera) + add video isolation transformer.. should do the trick..

nikko Posted October 12, 2005 Share Posted October 12, 2005 Ay up, I must say I carry a scope in boot and I use it a few times a week. My problem is that most of my fibers are provided by BT and as we all know, BT are always right!! So when they tell me a lack of data must be down to my kit, I stick the old scope on & prove 'em wrong. It's also useful having a digital scope, 'cuz then you can pick out a line of information, such as data on a UTC. In summary, useful for checking data but there's easier kit to use for checking video. I went up into the attic...I found a Stradavarius & a Picasso. Unfortunately..... Stradavarius couldn't paint, and Picasso made a shocking fiddle.

Guest cctvman Posted December 17, 2005 Share Posted December 17, 2005 Must agree to a point on your comment on BT & there it's not our kit After they vist you allways have video back & most times data, although most including the older fiber does have error & fail indication Ok off subject..... Scope's They are a great bit of kit to have if you are using data over the same coax for video as if you interference or bad data it is easy to see with a scope, apart from that i have never really ever had to use one for video signal alone, a peak to peak or even a decent DMM can do the same Oh last & not least the only other time i have ever used a scope was my radio days & the odd EAS system Regards Al Ay up,I must say I carry a scope in boot and I use it a few times a week.

They replaced their TX and, hey presto! Put the scope on the new TX and it showed a luvverly 5volts. I went up into the attic...I found a Stradavarius & a Picasso. Unfortunately.....
