Use For Multiple Experiments.

• Recording and measurement software
• Multiple probes available

Operational device for conducting ultrasonic experiments in reflection mode (pulse echo) or in through-transmission mode with ultrasonic probes 1 MHz , 2 MHz and 4 MHz . With the built-in transmission and receiving unit, time gain control (TGC), integrated analogue-digital converter and microprocessor for connection to the measuring and evaluating computer via the USB interface. Connection of the ultrasonic probes via robust snap-in sockets with automatic probe recognition. Compensation for losses of intensity in ultrasonic sound pulses passing through solid or liquid bodies by means of TGC with selectable threshold, start point, end point and TGC ramp. The most important function signals (trigger, TGC, A-scan signal (amplitude signal) and ultrasound signal) are available via BNC sockets on the front of the device.

Includes measurement and evaluation software for Windows operating systems. Screen display of the ultrasound signals (echogram) and the simultaneous TGC signal, whereby the A-scan signal and ultrasound signal can be recorded individually or both simultaneously in the echogram as a function of time or penetration depth. Display of all currently set system parameters (operating mode, transmission level, gain, connected ultrasound probes) calculation of frequency and cepstrum of ultrasound signal (FFT), depiction of 2-dimensional ultrasonic images (B-image) and the time characteristic of time motion reflection layers (time-motion methods).
