I am probably stuck with fabricating such a signal generator, for two
reasons:

1.  We will want to superimpose WWV compatible time code signatures on it to
fully test our product

2.  The FCC would go ballistic if I transmit on 60KHz, so the whole thing
will have to be in a big steel faraday cage with EMC gaskets on the doors,
and so on.

Maybe this is as simple as:

1.  Produce 60KHZ 5V signal
2. Superimpose a WWV compatible time code on it
3. put the whole thing into a very well shielded enclosure
4. Attenuate it with a variable resistor array by 1E-6 or so inside another
good enclosure
5. inject said signal into another well shielded enclosure using an antennae
that has a ghost of a chance of transmitting it


Now, a half-wave antenna at 60KHZ is only 7800 feet long, which will be a
little impractical to do in the lab.  Hmmmm...  Doesn't look so simple.
