The Rigol DG811 function generator has 1 channel and a bandwidth of 10 MHz.
The Rigol DS800 series is a series of extensive and affordable function generators. All the models have a vertical resolution of 16 bits, which you normally only find with function generators in a higher price range. This makes this series one of the best affordable 16-bit function generator series.
This series of function generators have a large number of different output signals and it is possible to combine pre-programmed waveforms and self-made waveforms. A new 'SiFI II' technology is used to generate the waveforms. This technology generates the random waveforms point by point and ensures that the signal can be restored without distortion. Furthermore, this series has 160 built-in 'arbitrary waveforms', which simulates many signals from technical applications.
The display of these generators is a 4.3" TFT color touchscreen. With this display, all settings for the desired function can easily be set. Furthermore, these generators have a USB port that serves as Host & Device interface.
The differences between the models are the channels and bandwidth.
