4 Setup
When the antenna extension is delivered with the radar sensor, a
false signal fade-out is carried out beforehand at the factory. False
echoes caused by the antenna extension are thus eliminated in the
signal processing system.
The false echo curve of a retrofitted antenna extension must be called
up and checked via a PC with PACTware. If assembly is correct, the
red echo curve will lie directly on top of the blue false echo curve. It
is generally recommended that the user carry out a false signal sup-
pression before setup.
When using an antenna extension, the position of the reference plane
for the radar measurement changes in some cases. This should be
taken into account for the min./max. adjustment. In chapter "Dimen-
sions" of this mounting instructions manual you can find specifications
regarding the reference plane in the dimensional drawings.
Setup is carried out according to the operating instructions manual of
the respective sensor.
