How do I get a received voltage signal? Answered

I would like to compare the results of the experiment and the onscale simulation in the paper.
The experiment is to measure the voltage signal received using a microphone that is 5.8 cm away from the Tx pMUT signal.
I've already checked the example of echo, but I don't know if it's an appropriate method.
Is there a good way?


  • Here is another example.

  • Thank you for your answer.
    However, in this example, one device appears to be transmitting and receiving both.
    I want to set one transmitting device (for constant acoustic pressure) and check the signal characteristics that multiple receiving devices receive.

  • Thanks. Yes, the example shows the transducer working as a transmitter and as a receiver. The concept is the same, you have to set it up to represent the physical setup (ie electrical connections etc). If you want a different setup, you will have to conceptualize what your receiver setup is like and implement it with the piez command. These examples, together with the echo example particularly PulseEcho_RX.flxinp, show how one might go about doing this.

    Please also see the command reference for the options on these commands.

  • Thank you for your answer. I've read both examples, and I'm writing a comment to make sure I'm right. In summary, my goal is to analyze the characteristics of each Rx pmut in a constant acoustic pressure.

    To do this, first design the Tx element as shown in the pulse echo example, and then save the .flxffl file using the echo command. After that, apply the .flxffl file to the y_max boundary of the Rx pmut I created. The circuit then uses the piez command to apply the receive circuit to the top electrode.

    Please check if my plan is correct.
    Thank you for always being quick and helpful.

    Additionally, I prefer intuitive Designer mode, but are methods like echo command or piez command only available in Analysis mode? I wonder if analysis mode has more functions than designer mode.

  • You are correct, there is much greater functionality available with Analyst mode. There is only so much functionality that can be implemented with a graphical interface. Designer will be interpreted into Analyst script, so the functionality in Designer is a subset of what you have with Analyst.
