@all

I am in the market for a function generator that will do pulsed waveforms with a good LCD display. I want to do some work with Joule Thief's  and solid state generators and some deeper wireless testing plus more.

I do not want to spend to much. Here is two I have found.

I think either of theses will work but the first one looks better but it does not say anything about pulsed Wave forms? Can any function generator do pulsed square wave forms?

And for those of you that have them where did you buy it from? And is 2-3 MHz enough for this type of testing?

thanks!

@kooler

Thanks for the inductor advice...make a huge difference!

Here are some pic's of the upgrade now only pulling uA and the led is brighter now!

wow...just noticed the uA pull is down to 13.7 and slowly lowering??

Kooler has this happened with your setup!  Doesn't make sence  now 13.6

I forgot to mention that the LED was still lit when I got home....that's almost 24hrs before I stopped it for this test....12.9uA

Hey stpure,

what type of inductor did you use and where did you place it?
