The FG085 MiniDDS Function Generator can generate a variety of continuous waveforms (sine, square, triangle, etc.) from 0 to 200KHz.
Based on Steve's glowing recommendation, I decided to invest in one of these little beauties. I don’t know about you, but I find there's something exciting with an air of expectation about an unopened package containing some electronic goodie sitting on one's workbench.
This function generator kit falls under the heading of "some assembly required." Happily, all of the finicky surface-mount devices have already been installed on the main board for you.
All that's left are things like the through-hole capacitors, connectors, buttons, and other bits and pieces. On the other hand, there are certainly enough of these to make you feel as though you are earning your keep.
Fortunately, the "quick start" assembly instruction sheet was very well done, and it really didn’t take long at all to pull everything together and set it running.
I'm also impressed with the intuitive interface and the associated ease-of-use. You can select between continuous waveforms of Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down). It's immediately obvious how to select things like the frequency (0 to 200KHz), peak-to-peak amplitude (0 to 10V), and DC offset (-5 to +5V) and set them to your required values. You can enter initial values using the keyboard then make fine adjustments using a rotary switch.
You can also use this little beauty to generate servo test/control signals with microsecond resolution with user programmable pulse width, amplitude, and cycle. All-in-all, I have to say that this $49.95 kit is well worth the money. The next step is to use it to drive my BADASS Display; watch this space...
