PureView Operation
The following sequence of actions describes a typical operating session with a PureView-based measurement
instrument.
1.
Configure the PC as described in the ‘PC Setup’ section and the PureView unit as described in the
‘System Configuration’ sections above.
2.
Connect a transmit/receive transducer, or separate transmit and receive transducers to the
PureView instrument. Given that high frequency ultrasound will not pass through air, a suitable
acoustic coupling material must be present between the transducer(s) and the sample that is to be
tested.
3.
Use the control software to configure the PureView instrument for the desired operation, either
Internal or External Trigger mode, and Pulse-Echo or Through mode.
