    Hi guys

    I want to get a function generator, just looking at ebay, is this one any good?

    If not, can you recommend me one for beginner, I will need one for leaning boost/buck converter, it's for electronics use.

    I am hoping to spend about US$200, thanks

    I think for $37 you might well get $37 worth of usefulness from it. I doubt it would be calibrated well or have great stability or output amp etc.

    If you don't have anything that type of hobby style signal gen would be a heck of a lot better than nothing. :)

    This one I've used and isn't terribly bad. The voltage readout for peak to peak doesn't match what a scope shows, but for $130, it's good for generating up to 2Mhz sine/square/triangle waves.

    I'd go for that before I'd buy one from eBay.

    I'd go for a good oscilloscope before a function generator as well, you can get a Rigol 60Mhz for a decent price. You'll want more bandwidth if planning to work with microcontrollers, but enough to get started.

    In shorter words, if electronics are a long term hobby, get a decent 100Mhz scope and at least the function generator I linked above, but preferably an Arbitrary waveform 25Mhz generator for about the same price as a scope.
