OK Guys - I have a question that's beyond my normal are of expertise...
I have a large UPB installation - and once in a while I notice changes/additions causing the signal to get weaker. Not bad - honestly my whole system works great and I'd recommend it to anyone - but, where I have my CIM's seems to be the most remote place in the house; and on the circuit with probably the most noise... I could move it but would rather learn how to keep the lines as clear as possible. I have no day-to-day performance issues, but I do notice upstart having trouble with 2 of my switches; and sometimes others will be unreachable.
So - how would one measure things on the electrical system to see how noisy they are? For instance, I installed a couple LED Nightlights this weekend - I'm pretty sure they are negatively affecting my UPB... then again, I also put up 35 strands of christmas lights and a couple inflatables - so who knows if it was something else... That's why I'd like to learn how to actually look at the noise these things generate and be able to test and find "signal suckers" and noisy devices.
I do have access to an oscilliscope and probably a gammut of other test equipment - but I need to know what to test exactly, and what to look for. Ideally I'll figure out a way to easily go around the house and test a handful of things so I know where I need to place filters. I'd also be curious if noise is coming in from the outside... my neighbor has taken up welding recently - so who knows.
Thx in advance for any tips!
