The UTM ultrasonic testing board is a combination of 4 channel pulser/receiver and high-speed analog to digital converter on a single PCI board. The board generates an electrical pulse which is transmitted to an ultrasonic transducer. The transducer converts the electrical excitation pulse to an ultrasonic pulse which then propagates into the test 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 which is then processed by the on-board receiver and analog to digital converter. This process is entirely adjustable by the end user—configurable properties include: pulse voltage, pulse width, damping, pulse/echo or through transmission mode, receiver gain, DC offset, low-pass filter, high-pass filter, rectification, sampling rate, trigger source—internal or external, and trigger delay.

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. For solutions requiring more channels, please refer to the PCIUT3100 all-in-one UT board and the DT16B 16-channel pulser/receiver switching board.
