The PAE dialog provides the following settings:
• Used Test Ports selects the analyzer port providing the input signal a
1
(DUT Input) and the
receiver port for the output signal b
2
(DUT Output).
• The radio buttons and input fields in the DC Power panel select the test model and the
parameters for measuring the DC power P
DC
supplied to the DUT. The constants can be
incremented with the step size defined by clicking the
buttons.
• Select Topology opens the Port Configuration dialog to define the properties of the test ports.
Either physical test ports or logical ports can be used as Input and Output instrument ports. The
graphics and messages displayed in the Topology panel are identical to the ones shown in the
More S-Parameters dialog. When the balance-unbalance conversion is switched on, the PAE is
calculated from the single-ended and differential mode wave quantities (see also Mixed Mode
Stability Factors).
To obtain reasonable results, the test model and the respective Constant must be selected in
accordance to the test setup.
Definition and measurement of PAE
The PAE measurement is based on the standard test setup for forward S-parameter measurements on
a 2-port DUT. An additional measurement to determine the supplied power P
DC
is required.
