i noticed that the resolution of the PPS TI relative to GPS is 10 ns. is
there a scpi command to get a better resolution?
a few trivial observations:
my boxes have been up and running for a few days only, but they seem to
behave pretty well. however, a few things kept me busy for a while: i
plugged the data cable into the diagnostic port of unit 0 because it is
the one that is on, while unit 1 is in stand-by mode. new values for the
cable delay, the elevation mask and the position were accepted and could
be queried, but they were not visible on the status screen and had no
effect (e.g. sats below the new angle were still used). only when i
plugged the cable into the diagnostic port of unit 1 (in stand-by) the
new values were accepted, displayed, and used. i find this behaviour
communication can be speeded up a bit by selecting 19200 baud instead of
the default 9600 baud.
i prefer UTC time displayed over GPS time. while it was possible to
switch to UTC time, it was not displayed in the status window. it was
necessary to power cycle (!) the units to see UTC time.
the units work nicely with GPSCon, even on my mac with CrossOver.
without all the information available on this list (and in the 58503
manual) i would never have been able to bring these boxes to life. many
thanks to the list!
