You are correct; it is a complete unit with a 1pps and RS422 output for time
and setup/control. I wanted to "try" to use 3 of them in/for time stamps for
triangulating lightning strike data. With a 100 ns timing accuracy I would
think it may work for my application.
The manual is available for
I also purchased two of these units.
Although I could not find a spec. It appears that it has the same Pinout as the:
ONCORE Remote GPS Antenna Receiver
ACUTIME 2000
Trimble Palisade
The Provided cable only brings out pins 1-5, 9, 11, 12
These Correspond to
Pin 01Red Vcc (+8 - 36 VDC)

We did a lot of characterization of crystal temp
vs freq in the E1938 development and never observed
any "aging" of these curves. Even on "green" crystals
with zero run time.

Thanks for the description, it is very interesting. I have a follow up
question if you don't mind.
How does crystal aging look on a graph of temp versus frequency. This
graph has some temperature point where the slope of frequency variation
goes to zero and the crystal is quite stable around

I just realize they do not provide any information on the software though
:-(
It is a complete GPS receiver actually, unlike the 58532 which is just an
antenna, neat!
Their nomenclature is confusing.

Sometimes, the answer comes from the most unexpected places: the 58534 data
sheet (not sure there is a "manual") is on the Symmetricom web site:
http://ngn.symmetricom.com/products/Subsystems_Components/58534A.asp
(it's on my web site too now)

I have the HP 58532A antenna manual on my web site. I have one of these
antennas. I am not sure what the differences are between the two though.

Hello Time Nuts,
Would anyone have a PDF manual and/or the configuration software or links to it
for a Symmetricon 58534A GPS Timing Antenna they would be willing to share ?
Many Thanks,
Phil Harwood

I am unsure of the relevance of the above statement but, being
