The Rigol DG5072 is a dual-channel, 70 MHz arbitrary waveform function generator built on Direct Digital Synthesizer (DDS) technology for high-precision signal generation across demanding design, test, and research environments. Each channel operates independently with adjustable inter-channel phase, delivering stable, low-distortion outputs from 5 mVpp to 10 Vpp into 50 Ω loads. The instrument combines a 1 GSa/s sample rate, 14-bit vertical resolution, and 128 Mpts arbitrary waveform memory to support complex signal synthesis and modulation tasks.
