The unit must be assembled. It's a kit. It was fine for me, but the fit&finish isn't that good. Some pieces are loose, the electrolytic capacitors were too tall for the enclosure to close, unless I was building it wrong. I put in shorter capacitors that I had anyway. The output is ok, sine wave looks fine, but IT HAS A DC OFFSET of about 3v. For my application, (I build tube guitar amps) I had to add a capacitor in series to take out the DC offset. Coarse control works as expected. Fine control doesn't seem as fine. Amplitude control does not go lower than 500mVp-p. I think maximum is 7Vp-p. I haven't tried triangle or square waves yet, not really necessary for me.

I installed these components in about an hour and it immediately started working. The waveform is as shown in the advertisement, but the sine and triangle waveforms have significant DC offset components instead of being ground-centered. Small general purpose generator for workbench. The frequency range is larger than advertised, which is good. The power supply must be adjusted for normal operation.

I got this kit because I needed a cheap frequency generator to troubleshoot audio equipment. Let my 13-year-old son assemble it so he can learn some electronic techniques and how to solder properly. He did a great job, it was perfect the first time! Here are some tips to help you, some things that are not immediately obvious.

The XR2206 is a fairly good part and this product uses the basic functions to provide a good signal source over the audio range and beyond. I bought it as an add on for an inexpensive modular synthesizer. All the pieces do not fit together well. The power connector is too long an interferes with the side. The leads on the back must be cut and files for the bottom to fit. But it does make sine, triangle and square waves over a wide frequency and amplitude range and it is tolerably temperature stable. The datasheet for the part will give you ideas for adding functionality and improving performance if you like hacking hardware.

to couple with the Quartz / frequency meter tester, this makes a cheap amateur lab generator. Weird behavior in the high frequencies but quite correct to use in LF generator (0-100kHz). Attention: - put a 10k + 10k voltage divider at the output of the square signal (10V) to enter the frequency counter at 5V.
