The PTTI 1PPS is defined in

    http://www.navcen.uscg.gov/pdf/gps/ICD-GPS-060B.pdf

It is 20us long and common in some applications. However the voltage
levels are a bit high...

=============================================

Interesting - none of the equipment I have here would conform either in 
duration or amplitude!  I am not PTTI complaint!  (But my NTP works 
beautifully).
