The multiplexer together with OPCARD 2.0 - PCI-bus Ultrasonic Card
or OPBOX 2.0 - Ultrasonic testing box, becomes complete ultrasonic testing device. Multiplexer operates with 32 ultrasonic transducers, and thus has 32 independent transmitting and receiving channels. Each channel is equipped with individual delay lines, which can be programmed so that the pulse transmitter on the channel is being shifted in time relative to other channels.
- 32 independent transmitting - receivingchannels;
All channels may be used at once for beam forming;
- USB or RS232 control interface
- BNC Trigger Input
- BNC Signal output
- 12V/2A power supply
Together with OPCARD 2.0 or OPBOX 2.0 and delivered Software Package:
- many phased array ways of measurement
- various image processing:
- conventional phased array processing,

|Principle of beam focusing by flat probe.
The delay value of each elements depends
on the aperture of the elements, type of wave, refracted angle, and focal depth.
|Example of linear scan performed by focused beam. Scanning is made at a constant angle along the probe length by a group of active elements.|
|Principle of sectorial scan. This is the most often format for medical sonograms as well as for industrial images. The sound beam sweeps through a series of angles to generate a cross-sectional image.|
