[time-nuts] WWVB PM Time Questions

[Dana Whitlow]

OK, it looks like you've got it.


If you have any programming skills or experience at all, it should not be
too
hard to write your own files for uses on the AWG.  And that's where the
beauty
and the power of the AWG come from.  Otherwise it's just an
expensive function
generator.

Cheers,

Dana
