Functions For Single-Ended (Unbalanced) Port; Balance-Unbalance Conversion (Option 313, 314, 413, Or 414) - Agilent Technologies ENA Series User Manual

Fixture Simulator
Overview of Fixture Simulator
when the fixture simulator is turned off.) Port extension moves the calibration reference
location by setting an electrical delay for a single-ended port. Port extension can eliminate
only electrical delay (phase shift) for each single-ended port. Loss or mismatch cannot be
eliminated by this function.

Functions for single-ended (unbalanced) port

The following three functions are applied to single-ended ports (unbalanced ports).
Balance-unbalance conversion can additionally be applied to such single-ended ports.
Network de-embedding
A function that uses software to remove an arbitrary network (50 W system) defined by a
two-port Touchstone data file from each test port (single-ended) and to extend the
calibration plane. This makes it possible to remove networks that create error elements
between the calibration plane and the DUT, thereby enabling a more realistic evaluation of
the DUT.
For the setup procedure of network de-embedding function, see "Extending the Calibration
Plane Using Network De-embedding" on page 153.
Port reference impedance conversion
A function that uses software to convert an S-parameter measured with a 50 W port
reference impedance into a value measured with an arbitrary impedance.
For the setup procedure of port reference impedance conversion, see "Converting the Port
Impedance of the Measurement Result" on page 154.
Matching circuit embedding
A function for converting an original measurement result into a characteristic determined
under the condition of inserting a matching circuit between the DUT and the test port
(single-ended). The matching circuit to be inserted is either selected from the five
predetermined circuit models or provided by a designated arbitrary circuit defined in a
two-port Touchstone file.
For the setup procedure of matching circuit embedding, see "Determining Characteristics
After Adding a Matching Circuit" on page 155.

Balance-unbalance conversion (option 313, 314, 413, or 414)

A function that uses software to convert the measurement results in an unbalanced DUT
state, which are obtained by connecting the DUT to the test port of the E5070A/E5071A,
into measurement results in a balanced state. Two test ports of the E5070A/E5071A are
connected to one balanced port of the DUT.
For the setup procedure of balance-unbalance conversion, see "Evaluating Balanced
Devices (balance-unbalance conversion function)" on page 158.
