Rigol DG822 - 25 MHz Function / Arbitrary Waveform Generator, 2 Channel

  • 25 MHz, two channel function generator
  • 2 Mpts memory depth (upgradeable to 8 Mpts)
  • 160 built-in arbitrary waveforms
  • Sample rate up to 125 MSa/s
  • Various modulation functions - AM, FM, PM, ASK, FSK, PSK, and PWM

The Rigol DG811 is a 10 MHz, single channel function generator which incorporates multiple instruments into one portable and cost effective device. The DG811 features 2 Mpts standard memory, which is upgradeable to 8 Mpts via software. In addition, the DG811 can be upgraded from a one channel to two channel instrument, simply by entering a keycode. Enabling the second channel does not cause any compromise in performance, and the unit would function equivalent to two independent signal sources.

The DG811 is a multi-function instrument - function generator, arbitrary waveform generator, noise generator, pulse generator, harmonic generator, analog/digital modulator, and frequency counter. It offers high performance at an unprecedented price point, and is ideal for applications including education, R&D, and much more.
