With a single Through, it is possible to perform a transmission normalization, compen- sating for a frequency-dependent attenuation and phase shift in the signal paths. Due to the R&S ZNB/ZNBT's calibration wizard, calibration is a straightforward, guided process. 1. Replace the DUT by the Through standard of your calibration kit. Make sure to dis- connect all calibration units.
