The use of cables and/or adapters does not effect the
final measurement result, if they were in place for
the calibration process. The vector error corrections
established during the calibration process elimi
-
nates cable and/or adapter effects as long as the
ports used are stable and exhibit good repeatability,
which is the case if good quality components are
used. Figure 7-2 shows such a configuration.
Many calibration kits include adapters that are
designed to have equal phase length. These parts
are called phase equal adapters (PEA). Anritsu
designs in-series adapters (e.g., K Connector M-M,
M-F, F-F) to be phase insertable when technically
possible.
When available, it is good practice to use PEAs to
establish test ports (Figure 7-3).
