NA (Network Analyzer) Mode
NA Mode Settings
All FieldFox settings and features are supported (except Parameter Conversion)
with mixed-mode S-parameters.
How to make mixed-mode S-parameter measurements
—Press Measure 1.
—Then More
.
— Then choose from the following:
— Scc11
Common reflect/common incident for logical port 1.
— Sdd11
Differential reflect/differential incident for logical port 1.
— Sdc11
Differential reflect/common incident for logical port 1.
— Scd11
Common reflect/differential incident for logical port 1.
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
How to select parameter conversions
—Press Measure 1
—Then select an S-parameter
—Then More
—Then Conversion
— Then choose from the following:
—Off
(default) No conversion is performed.
—Z Conv (--) or Y Conv (--)
Perform conversion for impedance (Z) or
admittance (Y). Then choose from the following for either:
——Auto
The displayed S-parameter is converted to the
appropriate Z or Y parameter: Refl for S11 and S22; Trans for
S21 and S12. When the S-parameter is changed, the
appropriate conversion changes automatically.
——Refl
The displayed S-parameter is converted to Z or Y
reflection, regardless of whether the S-parameter is reflection
(S11 or S22) or transmission (S21 or S12).
