# skrf.calibration.calibration.TRL.renormalize¶

TRL.renormalize(z0_old, z0_new, powerwave=False)

Renormalizes the calibration error boxes to a new reference impedance.

Useful for example after doing a TRL calibration with non-50 ohm transmission lines. After the TRL calibration reference impedance is the line characteristic impedance. If the transmission line characteristic impedance is known this function can be used to renormalize the reference impedance to 50 ohms or any other impedance.
