High-speed USB-2020 DAQ board with simultaneous sampling up to 20 MS/s per channel features two analog input channels with multiple input ranges up to ±10V. It can sample data from both channels at an overall rate of 40 MS/s to the onboard memory, or continuously stream data to a host computer at up to 8 MS/s. Each channel has its own A/D converter to eliminate channel skew and ensure phase information between channels is maintained.
