The device is optimised for the use of EMAT (electromagnetic acoustic transducer). The device was designed as an adapter to a standard oscilloscope it can successfully cooperate with other acquisition / signal processing devices. It is also well suited to use together with measurement card OPCARD 2.0 or measurement device OPBOX 2.0.
The device consist of:
Power supply;
Pulser adjusted to inductive load.
