Rigol DG1022 is now obsolete, limited stock remains once sold out recommended alternative unit is DG822.
The Rigol DG1000 series Dual-Channel Function/Arbitrary Waveform Generator adopts DDS (Direct Digital Synthesis) technology to provide stable, high-precision, pure and low distortion signals. In addition, there is a built-in high accuracy, wideband, frequency measurement function. The user-friendly panel layout, versatile interfaces, direct graph interface, built-in instructions and help system have greatly simplified the operation process - Intuitive for new users. The built-in AM, FM, PM and FSK modulating functions generate modulated waveforms at ease, without the need for a separate modulating source.
