Refer to section
A PAE measurement involves the following steps:
1. Select the "Measurement Type", according to the properties of your DC power
source.
2. Enter the parameters for the selected measurement type.
3. Establish the test setup (including the RF connections of the DUT and the DC
INPUT connections) as shown in the circuit diagram.
4. Close the "Power Added Efficiency (PAE)" dialog and observe the result in the
measurement diagram.
Measurement Type
Selects the PAE measurement type, depending on the DC power source in use:
●
DC source providing a constant, known voltage at (possibly) variable current
●
DC source providing a constant, known current at (possibly) variable voltage
●
DC source with variable (unknown) current and power
The three measurement types involve different test setups, input parameters, and DC
voltage measurements. For an overview, see
Note: The measurement types for "Constant Voltage Source" and "Voltage and Cur-
rent" require an additional non-zero, known precision resistor R.
