Chris,
I you look carefully there should be 1PPS on pin 6, about 1 us wide.
You need to adjust your scope trigger and advance the brightness because
of this extremely low duty cycle. Maybe you'll not see the signal but
your scope will trigger at 1 PPS. Or you can connect a counter and see
1 Hz.

I get about 2V peak to peak when loaded with a 10X scope probe only
1 +15V
2 return for #1
3 lock.unlock
4 +5V
5 gnd
6 N/C (but I see a tiny ~60MHz sine-like wave
7 10MHZ output
8 rs232 Rx
9 rs232 Tx

My E-bay FE-5680A finally arrived. (4weeks later)
Of the pins on the DB-9 connector, which one is the RF output?
The manual only talks about an SMA output.
I know this has been talked about before, but I cannot find the thread.
Thanks in advance& sorry for bandwidth,
