Sonia White S
Main Features
Sonia White S is a high performance phased-array ultrasonic module compatible with SONIA architecture. This module has 64×128 (multiplexed) UT channels with the maximum performance in analog electronics and in digital signal processing.
- 64×128 channels (the emission channels may be different from the reception channels, even using the maximum aperture of 64 channels).
- 4 Parallel Beam formers for emissions and 4 Parallel Beam formers chains for reception up to 32 elements.
- Bandwidth @-3dB from 0.3 to 20MHz.
- Negative square wave pulser, up to -100 V.
- High digital signal processing capabilities (DDF, digital filters, gates, signal types, etc…). Multiple DSP capabilities per parallel focal law (filters, data compression, …).
- 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.
