Hi The description from their tech guys is Very high gain front end. It's a saturating amp rather than a comparator. Sample boards arrived yesterday, it'll be interesting to see how it does. Bob On Apr 16, 2013, at 9:51 PM, Richard (Rick) Karlquist rich...@karlquist.com wrote: On

Very high gain front end. It's a saturating amp rather than a comparator. Wonder how it would work as a DMTD front end? Corby ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
