A PAE measurement involves the following steps:
1. Enter the measurement parameters.
2. Establish the test setup (including the RF connections of the DUT and the DC
INPUT connections) as shown in the circuit diagram.
3. Close the "Power Added Efficiency (PAE)" dialog and observe the result in the
measurement diagram.
The power supply R&S HMP2030 applies a configurable DC voltage U
0
between the
DUT ports, and measures the resulting current I
m
. With the resulting DC power P
DC
=
U
0
I
m
, the power-added efficiency can be calculated as:
PAE = (b

- a

Defines the DC voltage to be applied by the power supply.
Remote command:
"Additional Input" u0=<numeric value>;
Power Supply Port
Defines the power supply port to be used.
Remote command:
"Additional Input" dc1port=<int value>;
