Mounting the frame for the verification objects
The verification objects come with a frame that holds the objects. Screw the frame to
the DUT mounting table.
Figure 5-5: Installation of the verification object frame
1. Place the frame on the mounting table. The position of the frame is defined by the
mounting holes in the DUT mounting table.
2. Screw the frame to the mounting table with the Allen wrench. The required socket
head screws are included in the delivery of the R&S
QAR-Z40.
Performing verification
The verification process consists of five consecutive measurements with the verifica-
tion objects (square plates). The verification objects are labeled A to E.
1. Select verification mode in the application ("Options" > "Verification").
In verification mode, the R&S
QAR eliminates unwanted responses in the signal by
applying a time gate to evaluate the data. For verification, using this method is
mandatory.
2. Normalize the reflection measurement.
a) Put the metal plate labeled "E" into the frame.
b) Select "Normalize Reflection" to initiate a measurement.
c) Wait until the results are displayed.
d) Remove the metal plate from the frame.
The resulting image should show a homogeneous image (the colors should not
deviate too much). The mean reflection should be around 0
dB.
