Setting up the RF frontend
The following steps describe how to connect the antenna modules and a sensor
module in both, an RF shielded box or an RF test chamber.
Risk of antenna module damage
The PCB of the antenna module is sensitive. When touched, it can bend
and thus lead to measurement inaccuracies.
Never touch the exposed top or bottom of the antenna module PCB (printed
circuit board) during setting up.
Always hold the antenna modules by the housing.

NRPM-A90D, notice the feeds of the vertical and horizontal antenna
modules. You can find out the alignment with the identification numbers "1"
or "I" (vertical) and "2" or "II" (horizontal) on the carrier of the antenna mod-
ules.
To connect the sensor module to the controller PC, you have several options as

Setting up the RF frontend in an RF shielded box
For connecting the RF frontend components, perform the following steps:
1. In the RF shielded box, install a suitable antenna ring.
2. Mount the antenna modules.
3. Connect each antenna module to the antenna module cable connectors of the
