Modifying a Calibration Set
Y ou can mo dify a calibration set in the follo wing w a ys:
Reducing the n um b er of p oints measured after a calibration set has b een created.
Dening a frequency subset. Y ou can create a new set b y zo oming in on a frequency subset
of the original calibration set frequency range.
Changing the calibration t yp e. Create a new set b y c hanging the calibration t yp e. Y ou can
c hange an active t w o-p ort calibration (full, one-path, or TRL) set to a one-p ort calibration
set.
Mo difying a Cal Set with connector comp ensation. Create a new calibration set b y applying
connector comp ensation to an active one-p ort or t w o-port calibration set.
Reducing the Number of P oints After Calibration
This t yp e of mo dication allo ws the n um b er of p oints to b e reduced without aecting the
calibration or the endpoints of the curren t frequency range. Th us, after a calibration using
801 p oints, either 401, 201, 101, or 51 p oints can b e selected. This is accomplished b y
skipping o v er alternate frequency p oints. F or example, when the n um b er of p oints is reduced
from to 101 to 51, only ev ery other p oint is measured.
