The device contains in the box of the size of the notebook computer the OPKUD Ultrasonic testing card, pulser&receiver, interface and a separate power supply with own battery and could be connected to any computer with Centronics interface.

The device is well suited for ultrasonic measurements (Flaw detection, layer thickness measurements, TOFD etc.). It can be used with mechanical scanning elements or many multiplexed channels (the device is capable of controlling such devices). It can work in echo mode (with one transducer sending and receiving) and with two transducers (transmit mode, TOFD etc.). Software is included (Windows 9x, NT). The device can also work as standard oscilloscope.

OPBOX - Portable UT-unit, works with any computer with parallel printer (Centronics) interface

1 - software selected

Software features:

- Two windows: RF signal in the main window, in the second optional: zoom, FFT, rectified signal, filtered signal;
- Software amplification, filtering and averaging (allows to work with very noisy and weak signals);
- Build in DAC and TCG curves;
- Three signal memories, each signal can be stored and compared with any other signal.

Optional it is possible to make software versions for the special needs of the user.
