HP 5371A Frequency and Time Interval Analyzer w/ two 54003A from Fleabay for $200.00 + $49.74 Shipping. I've got some FE5680 Rb Standards, a NTBW50AA GPSTM, and (recently thanks to the forum), a Lucent RFTG-u REF0, REF1 package. When I started, it was easy - the Rb was correct

. But then I got a second Rb and suddenly I no longer knew what time it was
![Confused :-//](https://www.eevblog.com/forum/Smileys/default/confused0024.gif)
. So I picked up the NTBW50 to resolve the issue.... well that just made things worse

. Probably what I need is another GPSDO to finally clear all this up

. When the recent thread on precision timing references popped up I scored the Lucent RTFG setup for $100 (Shortly after they jumped up to $200 then a little while later they dropped it to $150.00. Glad I scored it @ $100). I finally concluded that the more precision clocks I have the less certain I am about what the correct time is. So, now I'm hoping that purchasing the 5371a will provide the ability to finally resolve my personal dilemma of what time is it

Special thanks to Ed Palmer for afflicting me with this nonsensical pursuit of determining when it's time to feed the cat aka Timenut
