5 CALIBRATION AND CALIBRATION KIT
106
of LINEs should be no less than three. The more LINEs you use, the higher the
accuracy you will achieve.
To employ multiple LINEs in the calibration procedure, use the same method of
standards subclasses assignment as in the regular TRL calibration (see section 5.3.4).
Defining frequency limits to calibration standards is not necessary for Multiline TRL
calibration method.
The procedure of switching between the normal and Multiline TRL calibrations see in
section 5.2.7.1.
The following table shows the differences between the regular and Multiline TRL
calibrations when entering the data into the calibration standards editing menu.
