Risk of antenna module damage when touching the PCB of the
antenna modules
(1)
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.
Antenna module cable (2)
Cable firmly connected to the antenna modules for connection to the R&S
NRPM-
ZD3 feedthrough or the R&S
NRPM-Z3 interface modules.
Note:
The contact durability of these connectors is limited, therefore note the
plug-in cycles specified in the data sheet.
Signaling LED (3)
LED for signaling purposes.
You can use the LED for mapping between the antenna module location and the
sensor module channel, or for own signaling purposes.
To turn on the LED, use the SCPI command
on page 111. The LED color is blue.

R&S
NRPM-ZD3 feedthrough module
The R&S
NRPM-ZD3 filtered cable feedthrough module combines up to three
antenna modules to one connector. From the cable feedthrough module, three
independent antenna measurements are led to the R&S
NRPM3(N) sensor mod-
ule over the R&S
NRPM-ZKD3 interface cable.
Measurements with R&S
NRPM3N LAN sensor modules require that you
use the latest version of the R&S
NRPM-ZKD3 interface cable
(1436.2984.02).
The filtered cable feedthrough is developed for use with a shielded RF shielded
box, e.g. the R&S
CMQ200.
