Positive PAE values indicate a gain in the RF power, negative values an attenuation.
The PAE is always smaller than 1.
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.
DC power measurement
For the R&S ZNA an external power supply is required to measure P

4.7.45 R&S ZNXSIM
With the R&S ZNXSIM PC simulation, you can have all the functions of an R&S ZNA,
R&S ZNB, R&S ZNB or R&S ZND on your desktop. Always accessible, even when you
do not have access to the hardware.
The same software that runs on the instrument (firmware) is used to run the simulation.
●
The R&S ZNA firmware simulates all available R&S ZNA models. It can be instal-
led in parallel with an R&S ZNB or R&S ZND firmware, but only one of them can be
run at a time.
●
The R&S ZNB firmware simulates all R&S ZNB, R&S ZNBT, and R&S ZND mod-
els. It also comprises the documentation for all these instruments.
●
The R&S ZND firmware also simulates all R&S ZNB and R&S ZNBT models, but
only comprises the R&S ZND docs.
