waveform generator

(1/6) > >>


I'm planning to buy a waveform generator, but i don't know how to make a comparison between brands: which specs should I consider?

perhaps start off with how your planning to use the thing? frequencies? voltages? currents? waveform purity? any need for arbitrary waveforms? etc

First of all, if you ask what gen to buy - you definitely don't need arbitrary one... Would be just a waste of money ;-)

Definitely depends on what you plan to use it for. I got a BK Precision 3011B, it's a 2mHz unit. Works good for general troubleshooting and I only gave $50 for it. The only thing I had to do was build a selectable attenuator so I could get the output voltage down to about 35mvpp. The lowest it would go into a 50ohm load was about 1.5volts pp.

2 mHz is useless for electronics, those kind of frequencies might be of interest for mechanical or some biological work. Generators for electronics purposes should span at the very least the audio range, and preferably up to a few MHz.
