Ultrasound/Ultrasonic Applications | Spectrum

Ultrasound

The use of Ultrasonic products is increasing as new techniques and improvements in instrument performance constantly expand the range of applications. Spectrum digitizers are ideal tools for making ultrasonic measurements and can play a key role required in the development, testing and operation of these products. Spectrum digitizers and arbitrary waveform generators offer a wide range of bandwidths, sampling rates, and dynamic range to match the broad spectrum of ultrasonic measurement needs. When wide dynamic range and maximum sensitivity is required high-resolution 14 and 16 bit digitizers are available for capturing and analyzing ultrasonic signals from 100 kHz up to 250 MHz in frequency. A cost effective range of 8 bit digitizers is also available to cover frequency ranges from 5 MHz up to 1.5 GHz.  Typical ultrasound applications include Non-Destructive Testing (NDT), Ultrasonic Testing (UT), Doppler Effect Flow-meters, Time-of-flight Diffraction (TOFD), Range Finding, Scanning Acoustic Microscopy (SAM) and Tomography (SAT), Medical Sonography and Ultrasonography, Phased array ultrasonics, Laser ultrasonics and Acoustic Emission.
