to avoid overlapping data points. Increasing the number of positions to 4 to 6 can
improve the accuracy. Moreover, using the predefined load positions of the standard is
recommended.
Figure 5-8: Sliding Match: GUI representation
A calibration is valid (and can be applied to the calibrated channel) if either the Match
or three positions of the Sliding Match have been measured. However, it is often desir-
able to acquire calibration data from both standards.
The R&S
ZNA can acquire correction data for up to 20 positions.
The analyzer combines the data in an appropriate manner:
●
The Match results are used up to the lower edge of the specified frequency range
of the Sliding Match (Min Freq).
●
The Sliding Match results are used for frequencies above the Min Freq. In general,
the Sliding Match provides better results than the Match within its specified fre-
quency range.

Cal Kit Files
Calibration kit files can be used to store the parameters of a particular calibration kit, to
reload the data and to exchange calibration kits from one network analyzer to another.
Cal kit file contents
Cal kit files are independent of the current recall set and contain the following informa-
tion:
