Greetings,
Is there an accepted form for the PPS clock pulses that are produced
by the various time equipment in use today ?
A 1 hz square wave ?
-- Does the duty cycle have to be exact or only its "rising" edge ?
Or can I do a rising edge PPs pulse that's active for 10ms then lowers ?
Is there an equipment manual(s) that you guys can recommend, that I
can refer to ?
Thanks, yet again,
-lenny
