Getting Started 1179.4986.02 03 26 R&SQAR50 Instrument tour System overview 5.1.2 Antenna cluster Number of clusters: 2 Function: The antenna clusters are located in the side body of the R&S QAR50. The antenna clusters contain the transmit and receive antennas. These antennas transmit and receive the signals to and from the DUT and digitize the resulting incident wave quantities, which are in turn the source for the microwave imaging. Depending on the system variant, the antennas have a vertical polarization or a hori-

zontal polarization. The variant with a vertical antenna polarization is required for measurements on radar covers with a vertical polarization. The variant with a horizontal antenna polarization is required for measurements on radar covers with a horizontal polarization. The R&S QAR50 contains two clusters:

Cluster "2" is located on the side of the connector board. Cluster "1" is located on the other side. For better orientation, the cluster numbers are printed on the corresponding cluster. 5.1.3 Absorbers Number of absorber sheets: 5 Function: The absorber sheets on the inside of the R&S QAR50 eliminate electromag-

netic interferences that would otherwise distort the reflection and transmission mea-

surements. 5.1.4 Mounting rail for the verification kit Number of mounting rails: 2 (one on each side of the main body) Function: The mounting rails for the verification kit are located in the center of each side of the R&S QAR50 body.
