What does a 32/128 phased-array instrument mean in terms of its capabilities?

The designation of a 32/128 phased-array instrument indicates its capability to utilize 32 pulsers and receivers in conjunction with its ability to address up to 128 individual elements in a phased-array probe. This means that the system can control 32 separate channels (pulsers and receivers) while also being capable of managing a larger array of up to 128 elements, allowing for enhanced beam forming and focusing capabilities.

This capability is significant in non-destructive testing applications, as it provides flexibility in how the instrument interacts with probes, optimizing the quality of inspections by allowing for detailed imaging and defect characterization across a wide range of configurations. This versatility is essential for the effective use of phased-array technology in various materials and geometries, leading to improved detection and sizing of flaws.

The other choices present misunderstandings of the term:

• The first choice incorrectly suggests a direct division of pulsers and receivers without addressing the element addressing capability.

• The third choice reverses the configuration, which does not accurately reflect the essence of a phased-array system.

• The last choice incorrectly implies the probe configuration capabilities instead of focusing on the actual functionality related to pulsers, receivers, and elements.

Understanding this definition equips practitioners with the necessary knowledge to choose the right equipment
