DAQ0754S 4-Channel Simultaneous PCI-express Data Acquisition Card

Product Functions

DAQ0754S accepts analog input signals connected to any of the four input SMA connectors on the board, performs simultaneous A/D conversion for all the four input channels with 14-bit vertical resolution at maximum sampling rate of 75MS/s, and transfers the digitized waveform data to application software via the PCI express bus inside a PC.   DAQ0754S supports high measurement duty cycle in continuous acquisition mode. When running at 75MS/s sampling rate with 14-bit A/D resolution, this board can achieve a sustained data transfer rate of  600MB/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.
