I have some very awesome REF CAPS that I am curious about. Do you trust this unit enough that I could say "verified and tested" if you checked them for me. (of course not for free, I am not a smug bag).
Cap Reference testing is a tough one. What Frequency if known were the caps specced at in the first place? Check out wae2w YouTube channel for a frequency generator/oscilloscope method to cross check your meters maybe?
Looking for an idea on what to do with most of this lot of bits? I have BNC, SMA and a few Type N bits I use and can't see me needing more than one of each of these. Anyone keen to add to their adapters or have a use let me know - postage cost only.
