[time-nuts] HP Z3815A manual/info needed

[Morris Odell]

Hi all,

A few of us down here in Oz have HP Z3815A GPS disciplined frequency
standards running. One of my friends, who does not belong to this group, has
had a fault develop in his unit which seems to be in the GPS receiver
section. The serial port terminal program  indicates that all is well but no
sats are being received even with an antenna change.

Are there any manuals or service information available for these units? Even
a block diagram? Any help gratefully accepted!

Regards to all,
