JDS2900 Series DDS Function/Arbitrary Waveform Generator User Manual

1. Introducció i finalview

The Walfront JDS2900 series is a versatile and high-precision dual-channel DDS (Direct Digital Synthesis) function and arbitrary waveform generator. It integrates multiple functions including function signal generator, arbitrary waveform generator, pulse signal generator, noise generator, and counter. Utilizing advanced large-scale integrated circuits and SMT technology, it offers high reliability and excellent performance for a wide range of applications in scientific research, education, and engineering.

Key features include a 2.4-inch TFT color LCD display for intuitive operation, a high sampling rate of 266MSa/s, and a 14-bit vertical resolution for exquisite waveform generation. It supports various waveform types such as Sine, Square, Triangle, Pulse, Partial Sine, CMOS, DC level, Half-wave, Full-Wave, and user-defined waveforms. The device also provides precise control over parameters like frequency, amplitude, offset, and phase difference.
