6.3.1 Connecting 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.
6.3.1.1 Connecting the RF frontend in an RF shielded box
When you are working with the dual-polarized antenna modules
R&S
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.
Required equipment
●
RF shielded box, e.g. the R&S CMQ200
●
Suitable antenna ring, see the accessories available for the corresponding RF
shielded box
●
One or more antenna modules, e.g. R&S NRPM-A90D or R&S NRPM-A90
●
R&S NRPM-ZD3 (2) mounted in the RF shielded box
●
R&S NRPM-ZKD3 interface cable.
●
R&S NRPM3(N) (1) sensor module
To connect the RF frontend in the RF shielded box
1. In the RF shielded box, install the antenna ring.
2. NOTICE! Risk of antenna damage. Observe "To prevent antenna damage"
on page 18.
Mount the antenna modules.
For connecting options, see the user documentation of the RF shielded box
you are using, e.g. as referred to in
Chapter 6.2, "R&S CMQ200 shielding
cube" , on page 42.
3. NOTICE! Risk of cable breakage. The connectivity of the antenna cable ends
is sensitive, and therefore the contact durability of the connection is limited.
Do not connect and disconnect the cables to the feedthrough board fre-
quently.
