In this calibration, ZX is shorted and the ratio between VO and VIN is measured. This measurement is called as GCAL,
Where VIN is the voltage across RG + ZX. In order to measure VIN, R41 should be removed and a 0-ohm resistor added to R42. For all other measurements, the default configuration should be used. This calibration is needed only in RG = RF = 100k setting, as seen in the next steps.
