Operational device for conducting ultrasonic experiments in reflection mode (pulse echo) or in through-transmission mode W/ ultrasonic probes 1 MHz (1018617), 2 MHz (1018618) & 4 MHz (1018619). W/ the built-in transmission & receiving unit, time gain control (TGC), integrated analogue-digital converter & microprocessor for connection to the measuring & evaluating computer via the USB interface. Connection of the ultrasonic probes via robust snap-in sockets W/ automatic probe recognition. Compensation for losses of intensity in ultrasonic sound pulses passing through solid or liquid bodies by means of TGC W/ selectable threshold, start point, end point & TGC ramp. The most important function signals (trigger, TGC, A-scan signal (amplitude signal) & ultrasound signal) are available via BNC sockets on the front of the device. Includes measurement & evaluation software for Windows operating systems. Screen display of the ultrasound signals (echogram) & the simultaneous TGC signal, whereby the A-scan signal & 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 & cepstrum of ultrasound signal (FFT), depiction of 2-dimensional ultrasonic images (B-image) & the time characteristic of time motion reflection layers (time-motion methods).Ultrasonic probes not included in scope of delivery.
