Two-channel USB data acquisition module for accurate under-sampling
This makes the module well suited for RF communication applications such as sonar and satellite surveillance and other areas where under-sampling is required for high-quality measurements. An external clock input enables the user to lock the under-sampling to a multiple of the signal under test.
The USB module provides two simultaneous analog inputs, each with a dedicated 16-bit A/D converter and an input range of ±1.25 V. The maximum sampling rate in streaming mode is 10 MHz for one channel or 7 MHz for two channels. The bandwidth of 300 MHz allows for precise and accurate under-sampling of periodic signals up to this frequency. In addition, the data acquisition module features 32 digital input/output lines, two counter/timers (32-bit), and three quadrature decoders. The analog inputs and the DIO lines can be run simultaneously and synchronously, and are galvanically isolated from the USB 2.0 port up to ±500 V. The module is available installed in a compact metal connection box with SMA connectors and ships with a comprehensive software package that is compatible with Windows 7, XP and Vista. The package comprises a comprehensive range of software development and integration tools, including 32/64 bit drivers for .NET, LabVIEW and MATLAB.
