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 (4 x) are included in the delivery of the R&S
QAR-Z40.
Verifying the system
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.

● Keep the verification objects clean and without fingerprints.
