If you select this mode, means the LCA uses a differential electrical input
or output for this measurement.
Whether the differential signal is the input to the DUT or the output from
the DUT, this uses ports 2 and 3 of a 4- port network analyzer.
If you select this mode, the LCA uses a single-ended electrical input or
output for this measurement.
