Title: TEMEX(now Spectratime) MCFRS-1 Rubidium Oscillators.
Post by: hgl on April 04, 2022, 12:49:03 pm

I have 9 Temex Rb MCFRS-1, of which 4 are good and 5 are bad. These oscollators could be ordered with up to 4x10E-11 / per month drift.  The best one I have (serial number 1265) could fortunately be one of these.

Some interesting documents and Adev, from the best I have (SN: 1265), against a Samsung UCCM-L8 GPSDO.

Monitoring of the startup process via RS232 from a good and a bad Rb.
