Wixom, Mich. - The DS2302 Direct Digital Synthesis Board from dSPACE has been modified to offer more powerful signal generation and speeds up to two-and-a-half times that of its predecessor for simulating complex sensor signal forms. In addition, it now has more options to generate demanding signal forms, such as those required for intelligent wheel speed sensors.
The DS2302 also has six digital signal processors (DSPs) and is designed for the fast, flexible generation of curve behaviors. It computes each signal sample just-in-time and outputs it immediately.
The new angular processing unit (APU) slave interface for each channel on the board, together with the Fast Analog Capturing Module, an optional extension, serve up more precise measurement of injection control voltages, making it easier to calculate the injection quantities for direct-injection engines, even with variable valve lift, while enlarged memory and new signal processors (TMS320VC33) contribute to the enhanced speed.
The signal parameters can easily be changed on-the-fly by a master processor board or from the host PC. Data exchange between the main application and an application running on one of the six DSPs is done by C programs, which users can either create themselves or put together from a range of existing programs.
