Hello.

PGA970EVM GUI provides phase value of LVDT output.

It is like this.

What formula is used for the calculation?

I mean I guess the phase value is calculated using DEMOD1_PH1DATA and DEMOD1_PH2DATA.

Thank you.

Hi Yoshioka-san,

Please see this other thread where I describe how to calculate the phase angle. This is how the calculation is done in the GUI.
