The Rigol DG821 pro is a portable single-channel function generator with a bandwidth of 25MHz. The function generator has a compact size, making it easy to use the function generator at home or in the field. The DG821 pro has a sample rate of 625MSa/s, 2Mpts waveform memory depth and the function generator supports remote control via Web Control. Finally, the function generator has a 7" touchscreen display with a resolution of 1024 x 600 pixels.
The function generator can be powered by a power bank using an USB type-C interface, which improves the user experience. It has multiple built-in waveforms such as sine, square and ramp and it has multiple output modes such as continuous and sweep. The function generator also has a frequency counter that can measure up to 1GHz and a built-in harmonic generator.
For a similar function generator with higher bandwidth, sample rate and memory depth, see the DG900 pro series.
