Seesii FG-100 DDS Generador de funciones es un generador de señales de baja frecuencia. Es de tamaño pequeño, función completa, fácil de operar y portátil. Su fuente de alimentación puede ser un adaptador CA/CC o una batería de litio. Trabajando con un osciloscopio, se puede utilizar para solucionar problemas del circuito electrónico, caracterizar la respuesta de frecuencia del amplificador de audio o medir la respuesta de impulso. Debido a la excelente precisión DSS y estabilidad de frecuencia, también se puede utilizar para calibrar el factor de tiempo de barrido para osciloscopios. También puede utilizar su onda cuadrada para calibrar el atenuador del osciloscopio o ajustar la respuesta del pulso de la sonda del osciloscopio.
Seesii Signal Generator es el instrumento ideal para ingeniería electrónica, laboratorios, líneas de producción, enseñanza e investigación científica.

The Seesii 1Hz-500kHz DDS Functional Signal Generator is a compact and versatile tool designed for hobbyists, engineers, and educators needing reliable waveform generation. Supporting sine, triangle, square, and sawtooth waveforms, it is ideal for testing, troubleshooting, and educational demonstrations. I tested this device for signal generation in circuit analysis and audio system calibration.Pros: ✅ Wide Frequency Range: Covers 1Hz to 500kHz, accommodating most low-frequency applications.✅ Multiple Waveforms: Sine, triangle, square, and sawtooth waveforms provide flexibility for various testing needs.✅ User-Friendly Interface: Intuitive controls and a clear digital display make setup and adjustments straightforward.✅ Compact Design: Lightweight and portable, making it easy to integrate into workspace setups.✅ Cost-Effective: Offers excellent functionality at a competitive price point.Cons: ❌ Limited to Low Frequencies: While suitable for many tasks, it lacks support for higher-frequency applications beyond 500kHz.❌ Build Quality: The plastic casing feels slightly less durable, potentially limiting long-term rugged use in harsh environments.Performance and Usability: The Seesii DDS Signal Generator performed reliably during testing, with accurate waveform generation across its frequency range. The signal stability was consistent, and the distortion levels for sine waves were within acceptable limits. Its ability to generate different waveforms smoothly with adjustable amplitude and frequency made it versatile for tasks like circuit tuning and teaching waveform concepts. The digital display is bright and easy to read, though the button placement could be more ergonomic.Comparison: Compared to similar products, such as the Koolertron 1Hz-500kHz signal generator, the Seesii device offers comparable functionality but at a slightly lower price point. However, higher-end models like Siglent function generators may provide additional features, such as higher frequency ranges and more robust casings, albeit at a higher cost.Who Is This For?: This signal generator is ideal for students, hobbyists, and professionals working on low-frequency applications who require a cost-effective and reliable tool for waveform generation. It’s less suited for advanced users needing higher frequencies or more rugged equipment.Conclusion: The Seesii 1Hz-500kHz DDS Functional Signal Generator is a reliable and versatile tool for generating low-frequency waveforms. Its compact design, ease of use, and cost-efficiency make it an excellent choice for basic to intermediate signal generation tasks. However, users requiring high-frequency capabilities or more durable construction may need to explore higher-end models.

Note: This is not an high amplified audio signal its just a generator. It can drive a small piezoelectric speaker to resonance. When using it to generate high frequency test signals, working as intended. Has many waveform modes. can ne used to calibrate test equipment or study wave forms.

Most of the time, failed to turn on at all. Other times it would turn on and the red front panel LED would illuminate but the display would NOT illuminate and would remain blank. Very rarely it would power up and appear to operate. No real packaging - came in an antistatic bag with the USB cable and VERY brief instructions. Nothing to prevent impact damage - no box or any kind. Amazon packaged it fine, but the product itself is unprotected. Possibly the cause of so many DOA items. I bought this as a quick to deliver expedient for a visit to some mountain top electronics I need to work on. Too late for alternatives I'll have to lug a much heavier unit this week. Too band, this could have been a handy option for simple tasks. Obviously, no chance to evaluate 'performance' as it wouldn't turn on reliably. Returning.

This function generator is about value for money, not accuracy or quality.The interface could use some improvement, but it gets the job done.

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 ±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!

La perilla de voltaje presento una falla, no da voltaje, cuando se intentaba girar la perilla, llegaba a dar señales de voltaje pero cuando se soltaba la perilla dejaba de funcionar.The voltage knob presented a fault, it did not give voltage, when trying to turn the knob, it would give voltage signals but when the knob was released it stopped working.
