Hi: If anyone has a manual for an Austron 2110 Disciplined Frequency Standard, I would be interested in a copy. Please feel free to contact me off-list. This is a really cool instrument that locks the frequency of its internal ovenized crystal oscillator to an external standard having superior long-term stability. Many thanks Tom Leedy Clarksburg, MD 20871 _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
