Dissolve Bal. Port
The Dissolve tab of the Balanced and Measured Ports dialog reestablishes a single-ended
(unbalanced) port configuration where logical ports correspond to (single) physical ports.
• Select Logical Port Number shows the current port configuration. Selecting a Logical Port # and
clicking Dissolve reestablishes a single-ended (unbalanced) port configuration.

Define Measured Ports
The Define Measured Ports tab of the Balanced and Measured Ports dialog selects the ports that are
used for the measurement.
Measured Ports
Measurements do not necessarily require all of the physical or logical ports of the network analyzer. To
save measurement time, it is recommended to restrict the measurement to the ports that are actually
needed. Note that the analyzer will actually perform a measurement at each of the measured ports.
Unused ports will not be considered for the calculation of mixed mode, Z- and Y-parameters.
