The PCUS 11 system was designed for PC-aided manual and/or automated ultrasonic testing with one to four ultrasonic channels in a PCI PC configuration. In combination with suitable software running on a DOS®, Windows 3.1*® Windows'95®, or Windows 2000® platform, a complete digital ultrasonic testing instrument is available for a wide range of applications. Battery powered portable PCs provide independence from power sources, which allows for use in most types of in-situ field inspections. The PCUS 11S records all ultrasonic data in their native RF format, permitting the use of a variety of data acquisition software, e.g. PCUSWare™, QUT, CPS-N™, Winspect™, etc. In addition, data analysis software, such as SAFT (Synthetic Aperture Focusing Technique), can be applied for the disposition of detected indications.
