Interpolated Error correction

You may want to use interpolated error correction when you choose a subset of a frequency
range that you already corrected, when you change the number of points, or when you
change to CW. This feature also allows you to change the parameters in a 2-port correction,
such as IF bandwidth, power, or sweep time. The analyzer calculates the systematic errors
from the errors of the original correction.
To activate interpolated measurement correction, press
