Re: Pulse Generator
- Have you considered using a microcontroller? I have a MPS430 running
beside me at the moment as a pulse generator. I imagine that you
could use a voltage divider and one of the ADC's to provide the
control. I believe that there is a temperature controlled voltage
source on the chip to give a stable control voltage.

- Best I can tell, it costs about $10,000 for the cheap one.
Seems if you want something similar, but can focus it by hand, try the
QX5 or one of the USB type microscopes.
