I need an electric stimulator that emits short impulses of electric potential for an experiment.
I would just use several batteries with two wires, but I need the impulse to be very short, in the order of a millisecond or less. I need to be able to adjust both the potential (<100 volt) and duration (~1 ms).
My questions:
1) Is there any stimulator like this available to buy?
2) If not, are there components I can buy and connect to a few batteries to cut of the voltage after for example one millisecond, to create a short impulse?
I guess I could use some kind of TENS therapy machine, but as I understand it they dont emit a single impulse but rather a series of impulses.
3) Can I manually set a TENS device to send only one impulse?
I do have an oscilloscope with a signal generator which I could use, except that it only emits 2 Volts and minimum duration seems to be 4 milliseconds which is too long. I could use an amplifier (or two) but it would not solve the duration.
All advice is very welcome!
Thanks in advance!
