  • Hardware for this data acquisition system consists of National Instrument BNC 2090 adapter, National Instrument MIO16E1 data acquisition card and a computer.

  • The function of BNC 2090 adapter is to simplify the connection of analog signals and digital signals to the DAQ board. BNC 2090 can be configured to use eight differential or 16 single ended analog input channels available.

  • The program for data acquisition was developed using National Instruments LabVIEW 8.6 software. In this DAQ system, TDC signal was used to trigger the data acquisition system. Crank angle signals from the shaft encoder were used by the program to operate in external clock mode.
