Hi,
I have two ultrasonic transducers and a pulser-receiver(5072PR).
One is the contact transducer, A120S (6MHz), from Olympus and the other is also contact mode transducer, but it is a customized ring-type transducer (2.X MHz) (like doughnut).
I have two questions.
First, when I turn on the pulser-receiver, the initial line signal occurs from ultrasonic transducer.
I was wondring what is this signal.
Second, the two different transducers have different signal shape as shown below.
The signal from the customized transducer look so shoddy and dirty.
Why is that? and how to improve this kind of noisy signal?Please let me know. I'm so curious about all of that.
