OPBOX Ultrasonic Testing Unit Key Benefits
The OPBOX device, in a form of box of the size of the
notebook computer, contains ultrasonic testing card, pulser&receiver and computer
interface. It has a separate power supply with own battery and may be connected to any
computer through a standard Centronics interface. The unique design of OPBOX unit and its
full interchangeability with each and every PC computer systems makes it perfect for any
specialized field and lab ultrasonic applications as well as for educational, research and
training purposes.
This innovative device is suitable for the variety of manual and
automatic ultrasonic testing applications (flaw detection, precision thickness
measurements, TOFD etc.). It can be even operated with any automatic scanning
hardware systems or multiplexed channels units (the OPBOX through its indexing control
is fully capable of integrating such devices). It can work in pulse-echo mode
(with one transducer sending and receiving) and with two transducers (transmit mode, TOFD
etc.). Included software is Windows 9x, NT compatible. The device can also work as
standard digital oscilloscope. The OPBOX unit can be equipped with the range of the
customized transducers.

Software features
 | Two windows: RF signal in the main window, in the second window the
option of zoom, FFT (Fast Fourier Transformation), rectified signal and filtered signal; |
| Software amplification, filtering and averaging (allows the elimination
of the noise interference when working with very noisy and/or weak signals); |
| Build in DAC and TCG curves; |
| Three signal memories, each signal can be stored and compared with any
other signal. |
