What do people think about these:
<http://www.tek.com/products/signal_sources/afg3000/index.html> ?
I am very tempted to get one of the mid range types...

My co-author, Paul Horowitz, purchase the middle unit last
week, and likes it a lot. One of his graduate students,
Andrew Howard, is using it for performance tests on an IC
that has 32 A/D converters, each running at 1GHz. Details
at http://frank.harvard.edu/~howard/pulsenet/ Andrew
spent years designing this new custom VLSI IC, which is
at the heart of Paul's new all-sky optical-seti telescope
experiment, http://seti.harvard.edu/oseti/
http://seti.harvard.edu/OSETI/allsky/
http://seti.harvard.edu/oseti/oseti_apj_preprint.pdf

Andrew told me he likes the Tek's scope-like display that
lets him immediately see which waveform he's selected, and
what he's doing as he twiddles with editing the waveforms.

Thanks! Great stuff to know about!

That looks like cool stuff. I enjoyed looking through all the photos
of the observatory construction and electronics.

That one hits a sweet spot, 25MHz is too low, 1 channel is too
few, and $9k is a bit too expensive.

Yes, that's exactly the one I was looking at.

I disagree. I do think the chances of success are very low (because
the number of technological extra-terrestrial civilisations in our
galaxy is probably zero). But, I might be wrong, and the potential
payoff is so large that it justifies continuing research in this area.

Besides, it looks like the group is privately funded, so I guess they
can do what they want!

Yes, and in the grand scheme of things this is a small and affordable
diversion of scarce resources. Not only that, I'm sure that the
experiences gained here will provide even better engineers for other
more 'down to earth' projects, elsewhere, which will benefit even more
from the fact of it. Probably at a net gain, all things considered.

I noticed that, as well.

The way I see it, there are only two or three possibilities for
Extraterrestrial Intelligence, the most likely being, if they're
so f---ing intelligent, they're probably avoiding Terra like
the plague ;-). Or, when they land, they land in the backwoods where
they won't disturb the locals, just like the Star Trek crew always
do (the 'Prime Directive') (this is why the sightings are always
by the backwoods folks), Or, they got almost as smart as us, and
had a nuclear war and wiped themselves out. Or, they're astral
entities (the flying saucers are actually angels, and only a few
people are privileged to see them.[1])

Should we vote on the status of the extraterrestrials? - Oh,
yeah, I forgot: (D) none of the above, there ain't no such thing.

I read in sci.electronics.design that John Devereux
I disagree. I do think the chances of success are very low (because
the number of technological extra-terrestrial civilisations in our
galaxy is probably zero).

How do you conclude that? Zero is not a solution of any of the
predictive equations.
But, I might be wrong, and the potential
payoff is so large that it justifies continuing research in this area.

Doomed to failure. They haven't taken into account that comm lasers are
limited to 100 kW by the Interstellar Council on Non-proliferation of
Weapons of Mass Destruction.
Besides, it looks like the group is privately funded, so I guess they
can do what they want!
But is the funding from humans? Any Eichs about?

And they may discover other, natural time-domain phenomena,
pulsar-type stuff.
