Rubidium Lamp Voltage | Electronics Forums

May 03, 2005· 'parts in 10^n' is not of concern. As penance for my sins in a former life, I once had charge of a calibration lab where the frequency sources were Rubidium referenced. They were dumped when the cost of new lamps or trips back to the manufacturer from the Middle-East became greater than new GPS-disciplined oscillators. Thanks - Joe
