Needless to say *demonstrating* this 0.001 db sort of gain flatness on a
repeater
out to crazy low frequencies is a bit involved. It *is* a great gig if you
happen to be
a consultant …

demonstrating 0.001 dB (or would that really be 0.1 mB or 100 microBels)
precision in *any* application is a bit involved. That's 0.03%
Yup, now do it at some silly low frequency ( 0.(some number of zeros)1 Hz ….
great way to waste a lot of time.
That's a volt meter....
It's the "do it at 1 Hz and 10 MHz and every 1 Hz in between" that is
the challenge.
