Thanks everyone for the suggestions on/off list. I had quite a few leads
to pursue.
I'm not looking for super high bandwidth cable, but it needs to be
better than the cheap blue semi-rigid cable I'm using now. It's a pain
to try to find some matching cables (I have seen some terrible mismatch
in delay and attenuation even though they all measured 3 feet). I'm
also concerned about bend radius and the impact on measurement
consistency.
Steve/Chris: I did search for Gore cable on Ebay and there are some nice
cables out there, just did not find anything that suit my needs. :)
Pat: agree that good quality cable is important together with good
calibration practice for model extraction purpose. I have seen the
impact of these factors on my measurement results.
Mark: thanks for the 3.5mm suggestions. That's also recommended by Gore
engineer.
Regards
Perry
