The YB3020 is a high-performance DDS digital synthesis function waveform generator, designed to meet the needs of various application scenarios such as scientific research experiments, engineering tests, and teaching. It employs advanced Direct Digital Synthesis (DDS) technology to stably output a variety of standard function waveforms, including sine waves, square waves, sawtooth waves, etc., with a wide frequency range from 0.1Hz to 20MHz and a frequency resolution as high as 1μHz, catering to diverse signal requirements from low to high frequencies.

The device also supports the editing and generation of user-defined arbitrary waveforms. With an arbitrary waveform editing function that supports a maximum sampling rate of 250MSa/s and a 16-bit vertical resolution, it can accurately reproduce complex waveform details. Users can draw waveforms through an intuitive graphical interface or directly import external data to generate specific waveforms, creating convenient conditions for testing in special scenarios.

Equipped with a 4.3-inch color LCD screen, the YB3020 features a hierarchical menu management system that supports real-time waveform preview and parameter interlinked adjustment. Its dual-channel independent output design allows each channel to have independent adjustment functions for amplitude, offset, phase, etc., with an output amplitude range covering 10mVpp to 20Vpp. Additionally, the device is designed with overload protection mechanisms and automatic calibration functions to effectively ensure the stability of long-term operation.

In terms of applications, the YB3020 can be widely used in various professional scenarios such as communication system debugging, electronic component characteristic analysis, medical equipment development, and also meets the basic teaching needs of university electronic laboratories. For easy system integration, the device is equipped with USB Host/Device interfaces, supporting data interaction with external storage devices and remote control from a PC. The built-in storage unit can save up to 100 sets of user-defined waveform configurations, facilitating quick recall of repeated experimental schemes.

The YB3020 adopts a compact metal housing structure, equipped with multi-function knobs and quick operation buttons, optimizing the human-machine interaction experience while ensuring professional performance. The product has undergone rigorous temperature cycling and vibration tests to ensure reliability in different environmental conditions.
