美國奧林巴斯-泛美超聲波脈沖發(fā)射接收器panametrics model 5073PR型英文簡介：
Model 5073PR:75
MHz (-3 dB) ultrasonic bandwidth with fast rise time spike pulser extends
performance for work with 50 MHz transducers in applications that challenge
limits in axial and near surface resolution.
These affordable
and reliable manually controlled pulser-receivers provide the perfect building
blocks for both conventional and high frequency applications. Each instrument
is designed for superior low noise receiver response and high performance
pulser control.
When used with an appropriate transducer and analog or digital oscilloscope,
Panametrics pulser-receivers provide the perfect starting point for ultrasonic
flaw detection, thickness gaging, materials characterization, and transducer
characterization.
