OPBOX 2.1 is a complete ultrasonic testing device, suitable for all ultrasonic measurements and due to many additional digital inputs/outputs and internal processor it can be used as a controller for more complicated devices.
Opbox 2.1 can work together with devices like multiplexers or scanners.
The box has an implemented one channel pulser & receiver and can be used with one or two transducers (one is sending, and the second one receiving).
The system allows to buffer many acquisitions in internal memory and forward whole packet of data to control application.
In this way, the high throughput of data reading from the device is obtained.
