LDC1314EVM: I want to know the Rp value of the CH0 sensor.

One way to determine Rp is through measurement with an impedance analyzer:

The link to the app note that shows how to do this, Measuring Rp of an L-C Sensor for Inductive Sensing, is given on the Inductive sensing FAQs on the forum landing page: https://e2e.ti.com/support/sensors/f/1023/t/295036 

The app note is also available directly at  www.ti.com/.../snoa936.pdf  

A technical article that tells how to set Rp without impedance analyzer measurements is available at

Please let me know if you have any questions.
