10Mhz Reference. Which one to trust: GPSDO vs Rubidium

The auction site has delivered to my home two pieces of equipment to be used for a 10Mhz reference. 1) Rubidium standard = Lucent RFG-M-RB. 2) GPSDO = One of the newer BG7TBL units with the blue LCD screen. For both of these units, who knows when the last time they were calibrated. After a few days of burn in, the two units are about 50 ...Web
