Dear Sirs,

I am using the EVAL AD5933 EBZ evaluation board with resonance PZT sensors. I am having a problem with the resonance part in the graph as it is flattening. Please find the graph as an example.

Can you kindly tell me why and how can eliminate this problem?

I thank you in advance.

Best regards,

Niki

Hi,

I just check in a new laptop with W10 32bits version and everything seems correct...

Could you confirm the version installed?

Note- I installed rev.B

Hi Miguel,

Thank you for your email.

The interested frequency is between 60 and 100 kHz. The Rfb and Rcal are 2950 ohms. The expected impedance is between 2000 and 10000 ohms.

I thank you in advance.

Best regards,

Niki
