I started putting it together following the instructions as best I could. I really don't know if the thing works well or not. I came across this kit and figured 'gee, if it's only $50 bucks, what can go wrong?' My instincts told me, don't buy it, my greediness won out. I was evaluating various hobby-level function generators in the $250-$500 price range.

This kit reminds me of the saying 'Buy once, cry once'. It can even be used as an adjustable DC voltage source by setting the amplitude to 0. The FG805 can generate a peak to peak amplitude up to 10V with an offset range from -5 to +5VDC. The incremental step size can even be adjusted to make sweeps over a wide range easier to handle.

Frequency, amplitude and offsets can all be set with the number pad and incrementally adjusted with the rotary encoder. The LCD screen and menu system make this an easy instrument to operate. Three different operating modes allow the FG085 to generate 7 different types of continuous waveform as well as servo test and control signals in micro-second resolution. Just solder the through-hole parts in place, attach the face/base plates and before you know it you'll be generating sinewaves at frequencies up to 200KHz! But that's only one of the tricks this thing can do. The FG085 MiniDDS Function Generator is a 'some assembly required' kit that becomes a flexible, functional and easy to use frequency generator.

Function generators are useful in a ton of applications from RF to embedded logic.
