I've been using several Rubidium standards similar those for sale. One is
10MHz, another is 15MHz.
I use the Rubidium oscillators to drive the external input to a HP 8406a
Comb generator. The HP normally puts out a nice comb every 1, 10 or 100MHz
out to 2GHz or so.
But using the Rubidium standards, I get a very precise marker comb every 10
or 15MHz out to about 2GHz. Plus very low phase noise. Good for testing
your filter pass-band, Q, etc.
"The rest of the Story" is in these pix:
