Test setups with R&S
NRPM3N LAN sensor modules and the R&S
NRPM-
ZKD3 interface cables for connection to a RF shielded box, require that you
use the latest version of the interface cable (1436.2984.02).
Single antenna module solution
The base configuration with one antenna module measures the power of the inci-
dent wave from the DUT to the antenna module, e.g. to calibrate the output power
of your DUT.
Example:
Setup with one single polarized R&S
NRPM-A90 antenna module installed in an
RF shielded box (feedthrough module):

Multiple spatially distributed antenna modules
With several antenna modules distributed in an area, you can test the beamform-
ing function of a DUT. The more antenna modules are installed, the higher is the
measurement accuracy during beamforming tests. In addition, you can derive
matrices for swiveling the beam of the antenna module around two axes.
