- DDS Signal Generator Module Development Board: This versatile module produces 2 sine waves and 2 square waves, offering a frequency range of 0-40MHz for AD9850 and up to 1MHz for square waves. Note that waveform purity may decrease between 20-30 MHz due to increased harmonics, but a 70 MHz low-pass filter significantly enhances the signal-to-noise ratio. - Adjustable Amplitude and Duty Cycle: Easily modify the output waveform amplitude using the dedicated DA reference pin. The duty cycle of the square wave can be fine-tuned with a variable resistor, allowing for precise signal customization. - Robust Oscillator Options: The AD9850 module features a 125MHz active oscillator, while the AD9851 is equipped with a 30MHz oscillator, ensuring reliable performance across different applications. The module supports both parallel and serial data input for flexible connectivity. - Compact and Space-Saving Design: Measuring just 5cm x 2.6cm, this module is designed to fit into tight spaces without sacrificing functionality. Applications: - Ideal for signal processing and testing in electronics labs. - Useful in communication systems for generating modulated signals. - Perfect for educational purposes, enabling hands-on learning about waveform generation and modulation techniques.
