Product Overview
The YB-1640H DDS Digital Synthesized Function Waveform Generator is a high-performance signal source based on Direct Digital Synthesis (DDS) technology, designed for electronics engineering, laboratory testing, and educational applications. It features advanced digital modulation techniques and programmable logic devices, delivering stable outputs of sine, square, triangle, and other waveforms. Key advantages include a 120dB programmable attenuator for microvolt-level signals and an Automatic Level Control (ALC) circuit to ensure long-term amplitude stability. The device supports external reference frequency input for enhanced precision and offers RS-232 interface for remote control and data transmission.114
Technical Features
With superior modulation accuracy and customizable waveform storage, the YB-1640H allows users to save and recall carrier frequencies, levels, and modulation parameters. Compact and lightweight due to SMT assembly, it suits both mobile and fixed installations. Its frequency coverage ranges widely with 1Hz resolution, while output voltage spans 0.3μVrms~1Vrms. Multiple modulation modes (e.g., linear/logarithmic sweep, FSK, ASK, PSK) and dual-channel outputs facilitate complex experiments like Lissajous patterns. The user-friendly interface includes a backlit LCD for clear operation.317
Applications
Ideal for R&D, production line testing, and academic labs, this generator replaces traditional high-frequency signal sources (e.g., XFG-7) in RF circuits, audio equipment, and sensor calibration. Its PC-compatible command set enables automated testing, significantly improving efficiency.120
