In the TAC32 documentation, you will read about Mouse data and GPS data !
Theres a command line switch to run that should resolve it.

That's not much more than what you spend putting

come close.
So, can I borrow $1k from someone? :)
How big would the sawtooth be for an m12+?
Warner
The M12+ has a 3x smaller sawtooth; about ±16 ns (9 ns rms)
vs. the VP sawtooth which is about ± 52 ns (31 ns rms). See:

Hi Brooke,
Good to hear from you.
The Austron 2029A used 10 MHz LO and a 75.42MHz IF. Power was 15VDC at
175mA.
The manual I have is pretty thin - no schematics just a spec block diagram
and an installation guide. Will email you
Hi Rob:
The Austron antenna is very straight forward. A 10.0 MHz ref is sent up the
coax along with 15VDC. The antenna multiplied by 50 and uses the 500 MHz to
drive a harmonic mixer thus subtracting 1500 MHz from L1 leaving 75 MHz to go
down the coax. Simple and clean.
