Advanced Ultrasonic Instrument

Sonia White

Main Features

Sonia White is a phased-array ultrasonic module compatible with SONIA architecture. This module has 32×128 (multiplexed) UT channels with high performance in analog electronics and in digital signal processing.


  1. 32×128 UT channels, multiplexed (32 receivers, 128 pulsers).
  2. Separated TX/RX for pulse-echo, through transmission and tandem applications.
  3. Apertures from 1 to 32 elements.
  4. Bandwidth from 0.45 to 28MHz (probes from 0.5 to 20MHz).
  5. Negative square wave pulser, up to -100 V.
  6. High digital signal processing capabilities (DDF, digital filters, gates, signal types, etc…).
  7. Small size that permits to minimize the length of the transducers cables, digitizing the UT signal very close to the transducers. This implies lower UT signal distortion, attenuation and noise.
  8. Replace the analog communication lines by digital ones, immune to electromagnetic interferences (fiber optic), which means no signal distortion and/or noise in the transmitted signals and performance independent of installation layout.
  9. Low power consumption. Rugged enclosure , protection degree IP54.
  10. Small size that permits to minimize the length of the transducers cables, digitizing the UT signal very close to the transducers. This implies lower UT signal distortion, attenuation and noise.
  11. Replace the analog communication lines by digital ones, immune to electromagnetic interferences (fiber optic), which means no signal distortion and/or noise in the transmitted signals and performance independent of installation layout.
  12. Low power consumption. Rugged enclosure , protection degree IP54
