Hi Team,
Cusotmer uses the PPC3 GUI to do speaker calibration. it is fail at temperature page as below.
Would you please provide your comment for this?

Hi, Scott,

Do you have any capture about the temperature graph of PPC3? We would like to verify how the Thermal Measurement is done by PPC3. In some cases, the device is not capable to reach the expected temperature and the test fails. Is it possible to take a capture or a video of the thermal measurement steps?

Best regards,
Luis Fernando Rodríguez S.

Hi teams:

First of all, thank you very much for your assistance.
Attachment is the step of our Thermal Measurement operation.
If there has any question, please don't hesitate to let me know. Thanks.

Hi, Odyssey_Lin,

Thank you for providing the video above.

Have you tried with a different speaker from the same manufacturer? Additionally, have you tried with different thermal parameters (temperature coefficient, increasing the thermal limit and excitation frequency)?

Best regards,

Hi Teams:

I have already replaced another SPK. For the original SPK, this new SPK has different temperature coeficient, but still encounter the temperature fit failed problem.
Then I change thermal limit or excitation frequency (change one of them at a time), but still encounter the temperature fit failed problem.

Thanks.

Hi, Odyssey,

Thank you for your testing.

Could you also provide the jumpers settings that you are using, please? Are both boards in default configuration? Are you providing an external voltage to the boards?

Best regards,
Luis Fernando Rodríguez S.

Hi Teams:

Thnk you for your reply.

Below are the jumpers settings and we didn't provide an external voltage to the board.

Thanks.

Odyssey,

Thank you for providing the details above. I don't find anything wrong on the registers settings or any other configuration that you are using? Could you try uninstalling PPC3 including all its folders and reinstall it again?

Best regards,
Luis Fernando Rodríguez S.

Hi, Odyssey,

Sorry for my late reply.

I have more questions regarding this issue.

Could you try using the output OUT2 (LS2) from the TAS2563 EVM instead of the one you are using? Do you have different results.

In the page that marks the temperature test failure (the one that you attached in your first post), did you try modifying the Thermal Fit Offset? Also, is you speaker heated before the test? Do you have its datasheet?

Thank you.

Best regards,

Hi, Odyssey,

In addition, could you try with other wires on J15 AMP_OUT of PP-SALB2-EVM? They seem to be too thin. You may even connect them to the J15 pins to ensure the connection.

Are you using the most recent version of PPC3?

Best regards,

Sorry for my late reply!

I would like to try to using the OUT2 from TAS2563 EVM, but how can i set the calibration output to OUT2?
The information about PPC3:

I have modified the thermal fit offset but no use and the SPK is always cool down before the calibration.

Thank you for your help and patience!

Hi Luis:

I changed the wires on J15 AMP_OUT of PP-SALB2-EVM like the picture below, but still had the same problem.

My PPC3 version:

Thanks!

Hi, Odyssey,

Do you have the same results when you connect the speaker wires to the white connector (J15)? It seems that the blue connector (J14) is not soldered correctly in your board.

Hi Luis:

Yes, I have the same results.
When I excute the "IV measurement" (red circle on picture below), I can hear a sound (sweep frequency), so J14 should be correctly soldered?
