AW: [time-nuts] Interfacing a 8dBm sine output of an OCXO to a digitallogic standard

[Ulrich Bangert]

Stephan,

if you like it i can send you the manual of a Efratom LPRO rubidium
standard in which several circuits for sine-to-ttl conversion are shown
and discussed in terms of low phase noise.

Best regards
Ulrich Bangert
