The Rigol DG4202 is a 2-channel arbitrary waveform generator delivering sine wave output to 200 MHz with Direct Digital Synthesizer technology. It combines function generation, arbitrary waveform synthesis, pulse generation, harmonic generation, and analog/digital modulation in a single instrument. A built-in frequency counter measures up to 200 MHz with 7-digit resolution. The 7-inch color LCD display (800 × 480 pixels) renders waveform shapes and dual-channel configurations in real time.
