5.1.1 Test Setup
Basic test setup
The basic test setup for radome measurements consists of the R&S QAR and a DUT
that is placed at a certain distance from the R&S QAR.
Figure 5-1: Basic test setup (distances in mm)
In Figure 5-1 , the red box indicates the area in which the R&S QAR takes the image of
the DUT. Note that the DUT must be positioned slightly off-center to the center of the
R&S
QAR as indicated in Figure 5-1 (141 mm).
Test setup with platform and DUT mounting table
When you use the optional platform and DUT mounting table, the test setup is already
predefined. The R&S
QAR is in a given position, and the DUT, when positioned on the
table, is already in the necessary distance to the R&S QAR and the floor. Note that the
position of the mounting table is variable, depending on the mounting holes you have
used to attach the mounting table. For more information, see
Chapter 4.2.3, "Installing
the Radome Measurement Elements" , on page 21.
