Programmable Pulses
(optional)
At the male connector Typ VG64 there are three programmable TTL outputs (Prog
Pulse 0-2), which are arbitrarily programmable using the GPSMON32 software.
Other technical details are described at the end of this manual.
Timecode outputs
(optional)
Abstract
The transmission of coded timing signals began to take on widespread importance in
the early 1950´s. Especially the US missile and space programs were the forces behind
the development of these time codes, which were used for the correlation of data. The
definition of time code formats was completely arbitrary and left to the individual ideas of
each design engineer. Hundreds of different time codes were formed, some of which
were standardized by the "Inter Range Instrumentation Group" (IRIG) in the early 60´s.
Except these "IRIG Time Codes", other formats like NASA36, XR3 or 2137 are still
in use. The board GPS167 can generate the IRIG-B, AFNOR NFS 87-500 code as well
as IEEE1344 code which is an IRIG-B123 code extended with information for time
zone, leap second and date. Other formats may be available on request.
At the male connector Typ VG64 there are IRIG-B modulated (3Vpp into 50 Ohm)
and IRIG-B unmodulated DC level shift.
