pulse

The received echo signal [S.sub.R] can be treated as carrying the information about the whole system (pulser, ultrasonic transducer and acquisition system) transmission properties

Lengths were set at 43 mm between centres (at which pulser and receiver were located).

The ultrasonic sensors, both 5MHz and 10MHz longitudinal UT, were driven by a pulser and a receiver.

Figure 2 shows the schematic of an on-line monitoring system consisting of a PC, a two-channel digitizer card, two pulser & receiver cards, an oscilloscope, and a frequency generator used for synchronization.

Simulated AE signals were excited by the PZT pulser attached on the pipe surface with varying distance and angle between the sensors and the source.

An add-on pulser is used to supply pulses for the second corrector.

The compact, modular VF-TLP Eclipse Transmission Line Pulser is a high-bandwidth tester that provides HBM, fast HBM, and CDM simulation during the engineering design phase of semiconductor production.

There are two AE sources, a pulser that simulates a growing defect, and a hammer that simulates mechanical noise of equipment.
