I have a similar unit that I picked up a few years ago. It only has a 1
PPS output. That's the way it was designed. There are so many
different versions of this stupid model that it's impossible to be sure
what you're buying until you get it on your bench.
If yours is like mine, the DDS is putting out 2^23 Hz (~8.39 MHz) which
then goes through a fixed divider to 1 Hz. You can access the 8 MHz
signal via a tiny socket on the DDS board. There is info online on how
to modify the unit to bring that signal out to a connector and program
it for other frequencies. If you change the frequency, the 1 PPS also
changes frequency.

Ugh... Hopefully he'll let me return it. This is the first time I've bought
an $80 item from China and I've been burned :(

If this is so, it has to be a very unfortunate mischance. I've been
trading with China numerous times, there was nothing to fault on.
