RS-232
The R&S NRT-Z43 and R&S NRT-Z44 directional power sensors have been devised
as self-contained measuring instruments with remote-control capability via a serial RS-
422 interface and can therefore be operated from a suitable computer. For use with a
PC or laptop, the R&S NRT-Z3 interface adapter is available for connecting the R&S
NRT-Z43/Z44 to a standard RS-232 interface (Fig. 1-1).
The sensor can be controlled via the supplied
Virtual NRT
Windows
user interface
(see chapter 2) or via a user program (chapter 3). The
Virtual NRT
program simulates
the user interface of a power reflection meter on the monitor and enables manual
power measurements.

Connection to AC Supply
The direct plug-in power supply for the R&S NRT-Z3 can be
connected to any single-phase AC supply with a rated volt-
age from 100 V to 240 V and a rated frequency from 50 Hz
to 60 Hz. It automatically adjusts itself to the local AC supply
so that there is no need for external switchover.
Four adapter plugs (Euro, U.S.A., U.K., Australia) are supplied with the sensor to adapt the direct plug-in
power supply to the socket outlet in question. For replacing an adapter, no tools are required; the
adapter is withdrawn and another adapter inserted until it engages.
The following safety instructions should be observed:
NOTICE
The direct plug-in power supply is intended for indoor use only.
Allow direct plug-in power supply with condensation to dry before connecting it to the AC
supply.
Observe permissible ambient temperature range of 0 °C to +50 °C.
The direct plug-in power supply is internally fused. Replacement of fuse or opening of the unit is not
possible.
