R&S NRP-Z27/-Z37
Operation via the R&S NRP-Z5 Sensor Hub
The R&S NRP-Z5 sensor hub allows up to four power sensors to be operated on one PC. It combines
the following functions:

4-port USB 2.0 hub

Power supply

Through-wired trigger bus

Trigger input and trigger output via BNC sockets
Equipment Supplied and Alternative Accessories
The following equipment is supplied:

Sensor hub

External power supply

Power cable

USB cable
Instead of the supplied, 2 m long USB cable, it is possible to use any other USB-2.0-certified cable
(USB connector type A to USB connector type B) with a maximum length of 5 m. If a locking connection
is required at the instrument end, it is also possible to use the passive R&S NRP-Z4 interface adapter
instead of a standard USB cable.
As an alternative to the supplied external power supply, power can also be supplied using a DC voltage
source with an output voltage of 12 V to 24 V and a power output of at least 24 W. Make sure that the
polarity is correct (positive pole inside, negative pole outside). The alternative DC voltage source must
be in the same building as the R&S NRP-Z5 and must be connected to the latter via a cable with a
maximum length of 30 m. Power must not be supplied from a low-voltage supply system.
The supplied external power supply is short-circuit-proof and is also protected by an internal fuse. It is
not possible to change the fuse or open the unit.
NOTICE The external power supply is not intended for outdoor use.
Keep within the temperature range of 0°C to 50°C.
If there is any condensation on the external power supply, dry it off before connecting it
to the AC supply.
