[time-nuts] Looking for some Frequency Electronics info....

Some time ago bought one on Ebay for under $50 just because it looked interesting. It isn't a prototype but most of the FEI units probably had limited production. It seemed to be more complicated than I expected it to be but if I understood it better it would make more sense. The 10Mhz board is

I recently got a strange little 1U FEI rack mounted unit called an FE-7923F-100-1, which appears to have rear 10MHz and dual 100Mhz outputs. it is called a Frequency Reference Unit. sadly, my unit has a fault light, and no outputs. All the internal supplies look good, and there is an FE-83AA

Re: [time-nuts] Rubidium for HP 53131A

Hi Be careful about air flow. Those counters have heat issues even in the stock configuration. The Rb is a bit of a power hog so it heats up as well. Not saying it won’t work, only that you need to be sure the air is moving in the right places. Bob > On Feb 19, 2018, at 4:18 PM, Skip Withrow

[time-nuts] Rubidium for HP 53131A

Hello Time-Nuts, A while back I acquired an HP 53131A, and a bit later added one of the Chinese knock-off 3GHz prescalers. Makes for a nice counter except for the very poor standard timebase. So, While researching the Option 010 and finding how outrageous the prices are running I found an
