rubidium, passively cooled
10mhz out, power switch and 15-19v dc in.
the rubidium box is about $150 on ebay (china) and takes 12v dc. it warms up in about 5 minutes and once its locked, its nearly an exact 10.0000000 MHz signal out in sine wave form.
a lot of people are now using these as their 'lab clock' source (modern freq counters and function generators often can use external 10mhz reference clocks instead of their local oscillator).
