- DDS Signal Generator Module Development Board: This versatile module outputs 2 sine waves and 2 square waves, with a frequency range of 0–40 MHz for sine waves (AD9850) and 0–1 MHz for square waves. Note that harmonics may increase, and waveform purity may decline above 20-30 MHz. An included 70 MHz low-pass filter enhances the signal-to-noise ratio. - Amplitude Adjustment and Variable Duty Cycle: The module features a dedicated pin that generates a DA reference, allowing for easy adjustment of output waveform amplitude. Additionally, the duty cycle of the square wave can be modified using a variable resistor, offering flexibility in your applications. - Oscillator and Flexible Input: The AD9850 module includes an active oscillator operating at 125 MHz, while the AD9851 module uses a 30 MHz active oscillator. It supports both parallel and serial data input, enabling seamless integration into various systems. - Compact Design: With dimensions of 5 cm x 2.6 cm, this module is designed to be space-efficient, making it suitable for projects with limited space. Applications: 1. Signal Testing: Ideal for engineers and hobbyists needing precise waveform generation for testing and calibration of electronic circuits. 2. Signal Processing: Use it in projects involving modulation, demodulation, or digital signal processing where specific frequency outputs are required. 3. Educational Purposes: Perfect for learning environments where students can experiment with frequency generation and waveform manipulation. This product combines functionality, compatibility, and a compact design, making it an essential tool for anyone working with electronic signal generation.
