Power Added Efficiency Measurement with R&S®ZNB/R&S®ZVA

Power Added Efficiency (PAE) is a key parameter for the characterization of an amplifier.

This application notes introduces two alternative methods how to do the Power Added Efficiency measurement. The first one is based on the R&S ZNB vector network analyzer (VNA) measurement function. Alternatively to this, the PAE tracer macro is introduced. This macro offers to make the PAE at an user selected compression point of the amplifier versus frequency. The PAE tracer macro is provided together with this application note.
