With the given parameters, it is possible to calculate the EIRP, using the following, sim-
plified equation.
EIRP [dB] = (P
RX
−
G1) + G2 + 20 * log R
−
G
RX
−
20 * log
λ
with
R = Air gap
λ
= Wavelength of the radar transmission
G
RX
= AREG antenna gain
G1 = Internal gain from RX waveguide port to power sensor
P
RX
= Received power at the AREG front end
This calculation is performed in the AREG, and the calculated EIRP value is shown in
the AREG display. It can also be requested by a SCPI command.

Analyzing the Radar Signal
With the R&S
AREG100A, a radar signal analysis in the IF domain is possible if a suit-
able spectrum analyzer (suitable frequency and bandwidth) is connected to the
R&S
AREG100A.
