Product Functions
DAQ0504M accepts analog input signals connected to any of the four input SMA connectors on the board, performs the A/D conversion with 14-bit vertical resolution at maximum sampling rate of 50MS/s, and transfers the digitized waveform data to application software via the PCI express bus inside a PC. The four analog input channels are multiplexed to one A/D converter on the board. The channel switching is controlled by software commands with channel switching time less than 1 millisecond. DAQ0504M supports high measurement duty cycle in continuous acquisition mode. When running at 50MS/s sampling rate with 14-bit A/D resolution, this board can achieve a sustained data transfer rate of 100MB/s to the PC memory, which corresponds to nearly 100% duty cycle and minimized dead time between transferred data records.
After installing hardware and software driver on the PC, the user can start the "SCI DAQ" software to test the functions of the product. The following software screen shots show the measurement results of different analog signals connected to the four input channels of the data acquisition card. Both the acquired raw signals and the FFT spectrum of the signals are shown.
