Hello,

Looking to see if anyone can guide me on how to measure the bandwidth of a video signal over a cable. I want to compare different resolutions over a 100' piece of 5-core coax. Thanks!

well a standard analog video bandwidth is ~ 6MHz give or take a bit. A Digital signal (from memory) is somewhat wider, and will depend on the mode used ... standard definition HD, etc etc.... a spectrum analyser will show you the bandwidth of both Analog or digital :)

losses due to attenuation will be a more defining factor over a 100ft run.

5 core coax ????? you will have to show me that one ! :)
or is it 5 core screened lead ?
