PZT receiver signal for Ultrasound transducer Answered
Hello,
I'm trying to measure the "receive" signal to design an ultrasound probe using 10MHz. Because of some problems, I am having a hard time using the program.
1. PZT Disc 2D (TxRx) - https://support.onscale.com/hc/en-us/articles/360019958231-PZT-Disc-2D-TxRx-
As shown in this post, both "transfer" and "receive" voltages should be shown on a single graph.
But when I used a signal with a frequency greater than 1 MHz, the "received" signal will not appear.
I want to measure the "receive" signal of a 10MHZ signal, what should I do?
2. Please let me know if you have any documentation on how to analyze the postprocessing data of this software, OnScale.
3. I created a simulation model using "designer", and saw the results in "post-processing". What can you do with the "analyst"?
I look forward to hearing from you.
Sincerely yours.

Hi there,
Thank you for your post. To answer your questions:
1. You may have to zoom into the curve to see the signal. You can share your files via your preferred file sharing service and I can check that the simulation is set up correctly.
2. Here is our documentation on post processor
3. Here is an article explaining what can be done in Designer, Analyst and Post Processor.
I hope this helps!

Thank you for your reply. I will check the documents.
And when I zoomed signals, I couldn't find any 'receiver' signals.
I want to share my files with you, but I can't upload my filles here.
Is there any other way to share my files with you like e-mail?
I look forward to hearing from you.
Sincerely yours.
No problem, please share your files with support and I can take a look.
Best Regards,

Thank you for replying.
I sent an email with title (PZT receiver signal for Ultrasound transducer).
Sincerely yours.
Hi there,
I have had a look at your model and noticed that your element size is set to 0.075 mm. We recommend having at least 15 elements per the shortest wavelength to resolve the frequency of interest efficiently. In your case this is 343 m/s/10 MHz/15 = 2.28666 um. You can choose element size using the Defined option in Mesh.
For more info on meshing practices have a look at our blog series!
