On http://www.thinksrs.com/products/PRS10.htm SRS says:
"Historically, the lifetime of rubidium frequency standards has been dominated by rubidium depletion in the discharge lamp. To avoid excess flicker noise, manufacturers would load less than 100 µg of rubidium into spherical discharge lamps. The PRS10 uses a lamp with a side arm loaded with 1 mg of rubidium. This design eliminates rubidium depletion as a failure mechanism, and provides better temperature control without excess flicker noise." Just out of curiosity, does anyone how much Rb is in the lamp of a LPRO-101? I don't recall seeing that figure in any of the docs! thanks, glenn _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
