I saw the formula to calibrate with a resistance but what C value or R||C values can I choose to calibrate correctly?
One more question, In RFB formula, Vpk would be 2.24+1.5 (Vdc+Amplitude) or 3 (V peak to peak)?
For the calibration using R||C, the same formula with calibrating using a resistor will be used. That is, you will have to calculate the equivalent impedance of your R||C calibrator then substitute it in the formula. Instead of using a complex impedance in calibrating the system, it is recommended to use a single resistor as the calibration impedance. For the Rfb formula, Vpk would be the peak voltage of the selected output range. You can refer to Table 1 of AN1252, just divide the Vpk-pk by 2 to get the Vpk value.
