Rigol DG1022A will be obsolete from 03/12/2018. All orders received by midnight on the 02nd will qualify for purchase. 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.
For further information, please refer to the 'SPECIFICATION' and 'DOCUMENTS, SOFTWARE & VIDEOS' tabs, above.
An overview of all Rigol function / arbitrary waveform generators can be found HERE.
