Review: Not bad for the cost - The FG-100 DDS generator is handy for casual testing of various projects (mostly in the audio range). If you are concerned about things like accuracy, jitter, rise and fall time, etc.. then this generator is not for you. It should not be used as a calibration standard... it's not that accurate. The display is a standard 16x2 LCD with a green backlight. The output can go as high as Β±10 volts (there is an internal voltage generator). The output filter really does nothing. The zero offset control works, but is rather useless. This little signal generator consists of an Atmel ATMega48v microcontroller driving an R2R ladder (8 bits) to generate the waveforms. The waveforms are precalculated and stored in the microcontroller's flash memory. A small loop written in tight assembler cranks the samples out to the R2R ladder to generate the signal. The rest of the code is ordinary C. You could easily add to the waveform library if you wish. Just generate it, store it to flash and add to the menu. The ATMega48v is clocked at 30.0 MHz. (!) which is way above it's spec, but it runs just fine and stable as ATMega's do. If you are an Arduino tinkerer and have a compiler and ICSP programmer, there is a third party program that you can program into an ATMega328p chip and improve the functionality of this generator (one handy feature being storing the last used settings in EEPROM so that the generator comes up the way it was last set. The buttons are also debounced much better). Search for "Alternate Firmware for FG-100". You will need the ATMega328p because the Mega48v doesn't have enough memory to add anything to the stock code. The 328 and 48 chips are, of course, pin compatible. All in all, this generator works great for what it is, and it's design makes tinkering with it or adding to it easy. It will be a both a useful tool and a fun platform to tinker with. I bought two of them, one to use and one to experiment with. I highly recommend it. Lots of fun! LOL! ## Features - 1HZ-500KHZ DDS signal generator is small but has many functions, easy to operate and carry. The power supply can be either AC/DC adaptor or a battery. - It can be used with oscilloscope to test and debug electronic circuit, the frequency response of audio amplifier and impulse response,It also can calibrate the sweep time factor of oscilloscope. - The square waveform is suitable for oscilloscope attenuator and the adjustment of probe impulse response. - Have a filter (can be opened and closed) to suit the output of sine wave and pulse wave. - This functional signal generator can test many kinds of wave forms such as: sine, square, triangle, positive and negative sawtooth waveform. It is especially designed for those professional worker. ## Technical Specifications | Specification | Value | |---------------|-------| | Item Weight | 100 g | | Product Dimensions | 13 x 10 x 5 cm; 100 g | | Item model number | FG-100 | ## Images ![Seesii 1HZ-500KHZ DDS Functional Signal Generator, DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform - Image 1](https://m.media-amazon.com/images/I/71-9KFD-XqL.jpg) ![Seesii 1HZ-500KHZ DDS Functional Signal Generator, DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform - Image 2](https://m.media-amazon.com/images/I/71dZ8KiCdBL.jpg) ![Seesii 1HZ-500KHZ DDS Functional Signal Generator, DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform - Image 3](https://m.media-amazon.com/images/I/71W68QJ1v0L.jpg) ![Seesii 1HZ-500KHZ DDS Functional Signal Generator, DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform - Image 4](https://m.media-amazon.com/images/I/71phss0fTIL.jpg) ![Seesii 1HZ-500KHZ DDS Functional Signal Generator, DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform - Image 5](https://m.media-amazon.com/images/I/71gs0gdw86L.jpg) ## Questions & Answers **Q: Can you generate an audible sound to be amplified?** A: You can connect this to a power amplifier only if the output AC voltage matches the input sensitity of your amp. Most amplifiers these days have an input sensitivity of either 0.775 VAC or 1.4 VAC. The manufacturer does not include in their specifications what is the output voltage. Before connecting to an amplifier you will need to measure the output voltage to see if it's enough to feed your amp. If not you will end up frying your amplifier and will need to connect to a preamp before connecting to your power amp. I tried this with a signal generator and learned the hard way. Honestly you are better off purchasing a signal generator and preamp since a signal generator gives you a wide range of wave functions to work with. **Q: Any ideas on how to hook it up to an amp with rca inputs?** A: If you are looking for a cable then https://www.amazon.com/CIMPLE-CO-Cable-Black-Professional/dp/B06XKLT756 if you already have RCA cable, then https://www.amazon.com/RuiLing-Female-Adapters-Coaxial-Connector/dp/B00VUG00FI **Q: Can this generate low voltage square waves (20-40 mV peak to peak)?** A: one can always place a voltage divider on the output to get very low amplitudes **Q: Can you set this to the Schumann frequency of 7.83 Hz? Can this generator pulse its output?** A: Mine can only be set in 1 hz increments ## Customer Reviews ### ⭐⭐⭐⭐⭐ I find it to be a really good unit! *by J***M on 27 April 2025* Operates really well! ### ⭐⭐⭐⭐⭐ Not bad for the cost *by R***K on 15 February 2022* The FG-100 DDS generator is handy for casual testing of various projects (mostly in the audio range).
