Description:

DSPUT5000 is a combination of a pulser/receiver and a high-speed analog to digital converter--both of which are located on a single board for the PCI bus. The board generates an electrical pulse with user-defined pulse voltage and pulse width. The pulse is transmitted to an ultrasonic transducer, and the transducer converts the electrical excitation pulse to an ultrasonic pulse which is propagated into either the tested material or couplant. The transducer also receives the echoes that are reflected back 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 80 MB per second.

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 is included with the board.

One of the unique feature is the on-board DSP chip from Texas Instruments. It runs 600 MHz clock and executes up to 4.8 gaga instructions per second. It is capable to process data at high speed for real-time peak detection, data compression, spray marker control, factory process control and feed back. With on-board DSP chip the board can run stand alone as a remote pulser/receiver and data processing system with a host control through RS232 serial port. A special DSP software development kit is available for customized data processing applications.

Along with our DT16B 16-channel pulser/receiver switching board, the DSPUT5000 becomes a multi-channel ultrasonic inspection and analysis system. The maximum number of channels is 256. Multiple DSPUT5000 boards can also be installed in one computer to build up a multi-channel ultrasonic system which can fire multiple transducers and acquire data at the same time.
