美國泛美高電壓超聲波方波脈沖發射接收器panametrics 5077/5077PR英文介紹:
Model 5077PR: 35
MHz (-3 dB) ultrasonic bandwidth and square wave pulser-receiver is ideal for
maximizing response in scattering materials. The square wave pulser is
particularly advantageous when testing with transducers of 10 MHz or lower, as
adjustable pulse width optimizes pulse energy, resulting in superior signal-to-noise
characteristic.
