Where can I buy a generator that will provide an output at 7200Hz and
run off of a house 110v outlet.

Hi buddy1,

What voltage level are you looking for on the output? Do you have
specific needs for a connector type? How much tolerance is there in
the 7200hz measurement? Do you need to know that, out of the box, the
machine will be producing 7200hz, or are you willing to check the
frequency on an oscilloscope and possibly make adjustments to the
signal generator?

Thanks,
smudgy.

Smudgy: Thanks. Frankly I do not know exactly what will work for my
new project. So yes, I can do some checking fine tuning; in fact, that
is what I should do. From the literature I have researched, about
7200Hz is what I need, but other literature implies that 17000Hz may 
work.  I need about a 100 volt, 1000 watt output. Again thanks.

Hi again buddy1,

So would a variable signal generator that is capable of a range of
frequency and voltage outputs be along the lines of what you're
looking for? I might be able to find a generator that can output 100
volts at 1000 watts over a continuum of frequencies including your
bounds (7000 and 17000hz). Would this be acceptable to you? Also, what
price range are you hoping for?

Thanks,
smudgy.

Hi buddy1,

Just thought I'd give an update. The one item I've found that would
approach what you need is an industrial-style signal generator that
goes for $1100. Its output is only 10 volts but it can accept an
add-on component that acts as a power amplifier that would produce the
output level you're looking for. (I don't know how much the add-on
component costs.) My feeling this might be out of the price range
you're looking for.

There are definitely much cheaper signal generators out there; a lot
of the ones I've seen output at around the 10 volt level. Maybe the
solution is to buy a 10 volt signal generator and a power amplifier
and amplify the output of the signal generator. The appropriate
amplifier would need to have a gain of 10 an output of 1000 watts, and
it would of course have to be responsive to the frequencies you need.

I'll keep looking for signal generators that meet your needs, but I'm
losing hope that there's one with quite the specs you desire.

Good luck,
smudgy.

these are very expensive and very european/asain generally used in the
vibration industry; i.e. precast concrete consolidation.

is this what you are trying to accomplish?

thanks

Thanks, but I would need the unit for a household use (relatively
inexpensive), rather than for a commercial or industrial applicaion.

Smudgy: Yes, great if you can find a unit like the one you allude to.
I am not definite on the price range, but your work would be completed
once you give a source or two for the unit.  Thanks. buddy1-ga
