USBDUX-SIGMA: Product Description
-
24 bits resolution
The USBDUX-SIGMA boasts 24 bits resolution on its 16 analgue inputs for data collection, analogue outputs for physical control and 24 digital inputs/outputs for event logging, counting and triggering. This board has twice the resolution of the USB-DUX-D board and has three times more digital I/O lines.
-
The only USB based DAQ with an open source LINUX driver available today
The low cost and flexibility of Linux with the power, speed and flexibility of the USB port. We supply a driver which is part of a well develop measurement API and not only some sample code how to hack the linux kernel.
-
Optical isolation
The sensors you attach to the USBDUX-SIGMA are electrically isolated from your computer inside the DAQ board. This means that there is no electrical connection between the two, so that your computer is insulated from any surges from the sensors. In turn any faults in the computer won't have any impact on sensors and pre-amplifiers.
-
Asynchronous acquisition
USBDUX-SIGMA is able to perform data acquisition in the background (asynchronous acquisition). This means you can run multi-threaded applications such as QT.
-
Small and lightweight
The USB DUX is only 144 x 90 x 30mm (Length, Width, Height) in its box. The board is 136 x 80 x 15mm on its own. Coupled with the ability to take power straight from the USB port and an embedded version of Linux makes the USB DUX the obvious choice for applications that can\'t be tied to power points and desk tops.
