OPKUD-01/100 is particularly well suited for ultrasonic measurements as well as other kinds of measurements which employ mechanical scanning elements or multiplexed channels (the card is capable of controlling such devices). Together with the pulser & receiver unit OPGUD-01 and an ultrasonic probe it could be used as complete ultrasonic testing device. OPKUD-01/100 is a short (8-bit) ISA card and can be installed in a standard PC computer. It can be also used as a scope card (only with external trigger).
