Re: [Amateur-repairs] Calibrating test equipment?

Clint, maybe I shouldn't have asked; all that rigging sounds over my head.

Back in the twenty teens, they were clearing these out on EBAY.  It was just the module but they were simple to get going.  Just needed +12 and +5 and away they went, outputting a 10MHz clock.

 

In the same box I put a GPS module that outputted a 10 MHz clock.  These were cheap as well and only needed a small antenna to work.  I also added an active splitter so I had multiple outputs.

 

The I managed to get a laboratory GPS time base, also off of EBAY, and this is the one I usually use.  It takes about an hour to get locked up tight so it is always powered up and drives much of my test equipment.  It's nice that they all sing off the same time base!

 

If I go portable and need accuracy, I take the rubidium clock.

Clint, how did you come by "my Rubidium time base."?  The ones I see advertized would clean my pockets out just for a down payment.
