Test and measurement procedure:

1. Perform the calibration without the additional two-port. During the calibration the

analyzer decreases the power sensor values by the 2-port transmission coefficients
to move the calibration plane of the power calibration towards the input of the DUT.
The calibration plane corresponds to the output of the 2-port which is placed in-
between the network analyzer port and the DUT.

2. Perform the measurement with the additional two-port.

Practical example:

On-wafer measurements. The power sensor cannot be directly con-

nected to the input of the DUT. The transmission coefficients of the wafer probe are used
for the power meter correction.

B: Two-port at power meter (during calibration)

Test and measurement procedure:

1. Perform the calibration with the additional two-port between the analyzer port and the

power sensor. During the calibration the analyzer increases the power sensor values
by the 2-port transmission coefficients to move the calibration plane of the power
calibration towards the input of the DUT. The calibration plane corresponds to the
input of the additional 2-port.

2. Perform the measurement without the additional two-port.

Practical example:

An adapter or attenuator with known attenuation is needed to con-

nected the power sensor to the test port of the network analyzer. The transmission coef-
ficients of the adapter are used for the power meter correction.

3.6 Offset Parameters and Embedding

The R&S ZNC functionality described in this section complements the calibration, com-
pensating for the effect of known transmission lines between the calibrated reference
plane and the DUT.
