Ultrasonic Pulser/Receiver Board for PCI Bus
PCIPR300 is a pulser/receiver board for the PCI bus. It generates an electrical pulse with a user-defined pulse voltage and pulse width. The pulse is then transmitted to an ultrasonic transducer, which converts the electrical excitation pulse to an ultrasonic pulse. The pulse is then propagated into either couplant or the material to be tested . The transducer receives the echoes that are reflected from the interface and converts the ultrasonic pulse back into an electrical signal. The on-board receiver processes the signal with the user-defined parameters. The signal from the Signal Out connector can be displayed by an oscilloscope or digitized by an analog to digital converter board. For the option of analog to digital conversion, please refer to our product PCIUT3100--our 100 MHz analog to digital converter board for PCI bus.
Other adjustable parameters of the PCIPR300 board include pulse voltage, pulse width, damping, internal relay for pulse/echo or through transmission switching, receiver gain, DC offset, low pass filter, high pass filter, rectifications, trigger sources, digital inputs and outputs, and internal trigger rates. Control software for Windows 95/98/2000/NT is included with the board.
Optional add-ons include a trigger-sync output connector, a logarithmic amplifier, encoder counters, a higher pulse voltage, narrow and wide pulse widths, DAC, and Windows software development kits.
Along with our DT16B 16-channel pulser/receiver switching board, the PCIPR300 becomes a multi-channel ultrasonic inspection system. The maximum number of channels is 256. Multiple PCIPR300 boards can be installed on a computer to build a multi-channel ultrasonic system with the capability to fire multiple transducers at the same time.
