In this case, for each port to be calibrated the same calibration standards have to
be connected. After connecting one of these standards, a calibration sweep has to
be performed for each channel.
This simple mode of parallel calibration is supported from the analyzer GUI ("Cali-
brate all Channels" checkbox in all calibration wizards) and via remote control (see

Calibrate a subset of the available channels, possibly using different ports and cali-
bration types, using

.
In this case, for each port to be calibrated a different set of calibration standards
might be required. For each of these standards only a subset of the available chan-
nels might have to be swept. See

This advanced mode of parallel calibration is available via
remote control only

Joining calibrations
The "JoinCal" functionality of the analyzer firmware allows you to join two calibrations
from an active channel or the calibration pool. The resulting calibration can replace one
of the joined calibrations, can be stored in a new channel, or added to the calibration
pool.
●
Frequency range join
Joins calibrations of the same port set, but with different overlapping frequency
ranges. The resulting calibration is of the same kind and applies to the same port
set, but covers the joint frequency range.
●
Port set join
Joins calibrations with the same frequency range, but with different port sets. The
resulting calibration is of the same kind and covers the same frequency rang, but
applies to the joint port set
The outcome is to expected to be a Calibrations of the same kind, with the same
frequency range, and the with joint port sets. Any calibrations on additional fre-
quency axes in the second input calibration will be copied to the output calibration
(see requirement 15).

Offset parameters and de-/embedding
The R&S
ZNB/ZNBT functionality described in this section complements the calibra-
tion, compensating for the effect of known transmission lines or matching networks
between the calibrated reference plane and the DUT.
4.6.1
Offset parameters
Offset parameters compensate for the known length and loss of a (non-dispersive and
perfectly matched) transmission line between the calibrated reference plane and the
DUT.
