DDS Function Signal Generator
Function and Role Introduction
Introduction
The DDS function signal generator is based on Direct Digital Synthesis (DDS) technology, offering excellent frequency stability that matches the internal crystal oscillator. It can generate a wide range of waveforms, including sine waves, square waves, pulse waves, triangle waves, sawtooth waves, TTL/CMOS signals, 50Hz signals, as well as more complex modulated signals such as AM, FM, FSK, BPSK, BURST, and sweep frequency. The embedded 1.5G counter allows it to function as a low-frequency digital sweeper. With fast frequency switching, low phase noise, and continuous phase change, this device ensures high accuracy and resolution, making it ideal for engineers, electronics laboratories, production lines, and academic research environments.
Key Features:
- Utilizes DDS technology for ±2.5ppm frequency stability (second stable, normal temperature)
- Features a 4.3-inch, 65536-color high-brightness LCD display with full Chinese interface for user-friendly operation
- Offers sine wave distortion below 0.15%
- Optional audio signal output functionality
- Includes ultra-low frequency sweeper function (optional)
- Uses advanced large-scale components and surface-mount technology to ensure high reliability, with a mean time between failures of several thousand hours
- Supports optional GPIB, RS232, and USB interfaces for flexible connectivity
- All parameters are digitally controlled for precision and ease of use
- Optional 50Hz signal synchronized with the main output
- Integrated 1.5G counter for enhanced measurement capabilities
