Has anyone used the thunderbolt PPS output with a N8UR FatPPS? I'm seeing a large (+-100-300us) amount of jitter on the output of the FatPPS. This same setup works fine with the input from z3801a (using a PECL/TTL converter) or the Fury (even though the Fury's pulse is wide enough to begin with). Is there something special about the thunderbolt PPS output? I noticed it seemed to require 50ohm termination to get a clean signal when I connected it to a counter (5334a) with a 3 foot cable.
I'm using the FatPPS in conjunction with a soekris 4501 with the tmrin mod. Scott _______________________________________________ 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.
