Description
Rigol DG822 Function Generator
The DG822 is a 2CH, 25MHz Function Generator with a maximum sampling rate of 125MSa/s. The Rigol DG800 series offers a user-friendly and high-performance function/arbitrary waveform generator solution at a very attractive price. Each instrument provides many functions including; function generator, arbitrary waveform generator, noise source, pulse generator, harmonics generator, analogue / digital modulator and frequency counter. Any Rigol DG800 series function/arbitrary waveform generator would be a valuable asset in any home, business or education laboratory.
