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.
- 32×128 UT channels, multiplexed (32 receivers, 128 pulsers).
- Separated TX/RX for pulse-echo, through transmission and tandem applications.
- Apertures from 1 to 32 elements.
- Bandwidth from 0.45 to 28MHz (probes from 0.5 to 20MHz).
- Negative square wave pulser, up to -100 V.
- High digital signal processing capabilities (DDF, digital filters, gates, signal types, etc…).
- 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.
- 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.
- Low power consumption. Rugged enclosure , protection degree IP54.
