Ultrasonic Pulser/Receiver and 100MHz A/D Board for PCI Bus
PCIUT3100 is a combination of a pulser/receiver and a high-speed analog to digital converter on a single PCI board. The board generates an electrical pulse with user-defined pulse voltage and pulse width. The pulse is transmitted to an ultrasonic transducer, which converts the electrical excitation pulse into an ultrasonic pulse. The pulse is then propagated into 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, and the A/D converter converts analog signals into digital data at a rate of 100 million samples per second. In addition, the digital data is transferred to a computer's RAM at about 10 MB per second. The resolution of the conversion is 9 bits, which can scaled from 0 to 511. The memory depth can reach up to 256 kilo samples.
Other adjustable parameters 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, sampling rates, external trigger, and adjustable trigger delay. A standard scope software for Windows 95/98/200/NT is included with the board.
Optional add-ons include digital inputs and outputs, an external clock input, a sync output, memory updates, an on-board hardware key module,a logarithmic amplifier, distance amplitude correction (DAC), up to two additional 14-bit analog to digital converters, and software development kits.
Along with our DT16B 16-channel pulser/receiver switching board, the PCIUT3100 becomes a multi-channel ultrasonic inspection and analysis system. The maximum number of channels is 256. Multiple PCIUT3100 boards can be installed on a single computer to build a multi-channel ultrasonic system with the ability to fire multiple transducers and acquire data simultaneously.
