In ldc1314, does Rs be measured by the user using a measuring instrument to obtain a value?
Or is there another way to calculate or measure Rs?
Please answer.

Hello,
Normally we recommend measuring Rp, not Rs. They are related values, which you can read more about in section 1.2 of LDC Sensor Design.
You can use the Spiral Inductor Designer tool to estimate Rp for a given coil design. This is a helpful tool for early prototyping. Once you have a physical coil, we do recommend measuring Rp using one of these methods. The goal is to configure the drive current so that the sensor oscillation amplitude is between 1.2V - 1.8V.
Best Regards,
