Mixed-Mode S-Parameters
In NA Mode ONLY, mixed-mode S-parameters (also known as Balanced
measurements) are available with Option 212.
Because the FieldFox has only two test ports, only reflection measurements are
available. Connect the balanced input or output of your DUT to the FieldFox
ports 1 and 2.
For highest accuracy, a Full 2-port calibration is required.
All FieldFox settings and features are supported (except Parameter Conversion)
with mixed-mode S-parameters.

To make balanced reflection measurements at the DUT output, connect the DUT
output to the FieldFox ports.

Parameter Conversion

In NA Mode ONLY, converts the active S-parameter trace to an equivalent
impedance (Z), admittance (Y), or reciprocal 1/S-parameter.
