Selecting the working mode
The system mode selects the radar positioning measurement test setup you are using.
You can either integrate the R&S
QAR in a custom automated system ("Inline" mode)
or use it in a stand-alone setup.
Inline mode: The R&S
QAR is part of an automated system. An adjustment of the
imaging height for the R&S
QAR is not necessary. Instead, the system mechanically
adjusts the location of the R&S
QAR in relation to the location of the radar sensor.
Stand-alone mode: The R&S
QAR is installed on the platform (R&S
QAR-Z21). For a
valid measurement, the R&S
QAR has to adjust its imaging height in relation to the
location of the radar sensor. The R&S
QAR takes this information from the car type
configuration.
► Select "Options" > "Inline".
A checkmark in front of the "Inline" menu item indicates that inline mode is active.
Selecting the car type
The car type configuration provides information about the car, the location of the radar
sensor and the measurement points (positions). The configuration is based on the
CAD data of the car.
In stand-alone working mode, the car type configuration also defines the imaging
height of the R&S
QAR.
Because every car type has different characteristics, you have to load the correspond-
ing configuration.
1. Select "File" > "Configuration" > "Import Configuration"
2. Select the configuration from the "Car Type" dropdown menu.
The R&S
QAR loads the corresponding data and adapts its imaging volume and
height. Loading another car type takes about 3 minutes.
3. Optional: If you change any settings that have an effect on the car type configura-
tion (for example limits), select "File" > "Configuration" > "Export Configuration" to
export the updated configuration.
Defining alarm limits
Alarm limits define by how much the position of the radar module may deviate from the
ideal position. If the results show a deviation greater than the limits, the test fails.
1. Select "Options" > "Alarm Limits" to open the corresponding dialog box.
