Signal preamplifier OPLabBox 1.2.

ultrasonicelectronic

OPLabBox is particularly well suited for ultrasonic measurements. Wide bandwidth amplifier with switched bandpass filter and integrated pulser makes these device suitable for variety of ultrasonic applications. It is designed to work as an self sufficient scope adapter, however it can be used as expansion box to other signal processing devices. Together with our ultrasonic testing devices (OPCARD or OPBOX) enables to implement complete ultrasonic system with full hardware and software support.
