RIGOL DG2041A/DG2021A Function/Arbitrary Waveform Generator Data Sheet
The DG2000 series function/arbitrary waveform generators from RIGOL use direct‑digital synthesis (DDS) to provide precise, low‑distortion signals. They support 10 standard waveforms, user‑defined arbitrary waveforms, and a range of modulation types (AM, FM, PM, PWM, FSK) with extensive I/O options including USB, LAN, RS‑232 and GPIB.
Key features include a 100 MSa/s sampling rate, 14‑bit vertical resolution, up to 512 kpts waveform length, and built‑in UltraWave software for editing and storing arbitrary waveforms. Ordering information, warranty details, and contact locations for service centers are also provided. This manual is written in Chinese.
