Phase Difference Measurement

Question asked by ramardan on Oct 1, 2008

Hi All,

I am testing the following system

Combiner-->Splitter-->Feeders-->Patch Panel

When I test the phase difference between the Splitter outputs I have a somewhat smoothish line and less than 1deg difference, similarly for the feeders which we have cut to length. When the feeders are connected to the splitter and the splitter and feeder are measured the signal is wavey, appears to increase and is upto 3-4 deg out of phase. The feeder and splitter are not moved between the measurements and there is no interference from other signals.
Can anyone offer advice on what the issue could be.
Thanks for your time
