Overview
PureView Instruments comprise a family of Pulser-Receivers that are USB controlled and powered. The
various PureView models span a broad range of operating frequencies that enable a correspondingly broad
range of ultrasound system applications. User control of these instruments is achieved through commands
sent from a computer to the instrument via the USB interface. The JSR .Net Control Panel Software, a
Windows-based software application, provides such control, and programming information supplied with the
Software Developers Kit (SDK) and Programmer’s Manual allows a user to develop custom software programs
for controlling PureView instruments.
All PureView models are designed to be physically interchangeable which allows users to rapidly alter their
system configuration by interchanging models. PureView is an excellent choice for ultrasonic system
applications such as flaw detection, quality assurance, material characterization and transducer testing.
The
PureView instrument enclosure is water resistant although care should be taken to keep the instrument dry.
Connections are easily made to PureView hardware by attaching coaxial cables to PureView’s four female SMA
interface connectors, and PureView Pulser-Receivers synchronize with other system hardware by producing or
accepting trigger pulses on the PureView Trig / Sync connector.
PureView instruments receive power through the USB interface. PureView is thus ideal for use in PC-based
ultrasonic testing and inspection systems, and its small size and relatively low power consumption enable
systems to be implemented using portable computers. PureView can be combined with A/D Boards or other
signal detection and processing instrumentation to give system integrators the flexibility to optimize system
cost and performance.
Theory of Operation
Communication with a PureView Pulser-Receiver provides a user with control over the receiver input signal
selection (T/R or Through), the receiver gain, the low-pass and high pass filter values, the pulser repetition
frequency (PRF), the transducer damping, and the enable/disable control of the pulser power supply.
