The welding installation considerations, follow these steps:
1. The components are welding the front board, from low to high principles, namely the first low welding components, such as, capacitor, resistor, diode, etc.
2.Welding IC socket, terminal blocks, finally power socket, adjustable potentiometer.
3.The back with a diagonal cutting pliers to cut short the pins as far as possible.
Debugging steps:
1.After completion of welding on IC, XR2206, pay attention to the direction of IC, insert the might damage the chip!
2. check the IC whether against, such as anti please timely correction.
3. Insert the power supply, power supply for 5.5 * 2.1 port, inside outside is negative polarity. For 9-12 v power supply voltage. The waveform may not be stable for more than 12V.
Using the step:
1. J1 jumper cap plug in, SIN/TRI blue terminals output sine wave (note J1, J2 can only insert one of)
2. J2 jumper cap plug in, SIN/TRI blue terminals output triangular wave (note J1, J2 can only insert one of)
3. SQU blue terminals output pulse
4. AMP : Sine wave, triangle wave amplitude adjustment
5. FINE : Frequency fine adjustment
6. Coarse : Frequency of coarse adjustment
Package include:
2 X Signal Generator Kit, XR2206 Precise Function Signal Generator Frequency Module

This set is the best t I've found. I have built these kits from several different sources and they all fell short in some ways - even to the point that some couldn't be finished because of missing or wrong parts. This set is better in several ways: 1. All the parts are supplied and are correct. 2. The integrated circuit and its socket are shipped in a small block of foam for protecting the pins. 3. There are five levels of frequency settings instead of four. 4. The highest frequency actually goes a little beyond 1MHz while other kits top out at around 0.8MHz. 5. The quality of the resisters, capacitors, etc. seems to be better for accuracy. 6. The top of the acrylic case is etched labeling everything except the power socket. 7. There are two kits so a tutor and student can each build a kit together. 8. The instruction sheet is easy to read and provides more information. I can recommend this set over the others I have tried.

Quick and easy to assemble. Work as it should.

This kit works exactly as I expected it to.Having watched videos of others assembling and testing this kit I knew that the amplitude control operated in reverse of what I wanted so altered the circuit board to reverse the amplitude control operation.I plan to design my own case for the second unit with the POT's mounted on a sloped portion of the case and wires routed to the circuit board. With this configuration is won't be necessary to alter the circuit board but instead cross connect the outer wires of the POT.If everything works out, I'll post the design on Thingiverse.

Just a cheap piece of garbage. Amplitude control functions in reverse to what you think it should. Mounting screws are too short to fit the board into the case. Save your money and your time...

You cannot alter the amplitude of the squarewave (although the circuit you build around this device could easily account for that with either an amplifier or a resistor), but the amplitudes of the triangle and sine waves can be altered. The frequency can be altered with decent gradations, and the waveforms look pretty good, considering I got this for so cheap and assembled it in a hour or so :) Also, the acrylic casing (which is hard to remove from the protective paper) makes it look really cool.

When I first put power to this I used a 9v battery. It was OK, but with higher frequencies it was getting unstable. So I decided to use a 12v source, it works better, a little bit more stable over the 9v. Also hooked a 10uf capacitor to the sine output, which helped. The highest frequencies (65K-1Mhz) gave me 354Khz-4.4Mhz sine waveform. Crappy sine wave at this frequency. All other frequencies gave me a nice waveform.

Not the greatest technology or sturdy container. You pull jumper pins to change setting. A neat evening "science project" or soldering tutorial, but not a reliable signal generator. Fun, and you get what you pay for, but not a tool or reliable instrument by any means. Good stocking stuffer for the younger electrical enthusiast.

I have used several of these for DIY electronics and all have gone well and worked well except one that blew a cap when power applied. The paper provided showed the cap size needed and fortunately I was able to replace it and it worked. In general these are great and handy for small simple applications
