Hi
Not just positive and negative, is the even second output closer than the pps
output. Since
you have dug a signal out of the guts of the thing, you need to qualify what it
actually is.

The very real question is still - which edge is correct?
Has anybody seen a GPSDO where the leading edge of a narrow pulse wasn't the
correct one?

Ignacio, I would very much appreciate a copy of whatever schematics you
have, even if it is not guaranteed to be 100% accurate
I agree with you that the 9.9804 Mhz is basically useless, while the
even second pulse is merely almost useless. However, as you have
apparently looked the board over
Hi Ed,
While your board is not exactly the same as mine I think that the
schematics are almost identical but the TPs and probably the chip names
has changed. I think that the main difference is that your unit can be
powered with -48 V or +24 V and obviously the parts layout has changed.
I

Is it really useless?
How stable or clean is it? Would it be useful as the reference input to a
DMTD?
I believe the antenna cable feed delay is going to work in the wrong
direction here
Have you tried a negative number?

Hi Ed,
I am the one who discovered the 1PPS pulse while troubleshooting a
NTG550AA. Instead of reuse the 1/2 PPS output and missing this signal,
my plan is to recycle the 9.8304 MHz output circuitry and connector, the
circuits are almost identical. So I will cut the trace that goes from
