1.6 Operating the Sensor on a PC via the R&S NRT-Z3 Interface
Adapter
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
(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
RS-232
power measurements.
1.7 Connection to AC Supply
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adapter is withdrawn and another adapter inserted until it engages.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:
The direct plug-in power supply is intended for indoor use only.
NOTICE
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.

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.
