–
R&S NRP-Z3 or R&S NRP-Z4 (USB adapter cables) for sensors of the R&S
NRP-Zxx family
●
Connection via R&S NRP-Z5 sensor hub
The R&S NRP-Z5 USB sensor hub (high-speed USB 2.0) can host up to 4 R&S
NRP sensors. It provides simultaneous internal and external triggering of all con-
nected sensors.
Requires additional cables, depending on the used output connector of the hub.
Choose one of the following:
–
Short extension cable R&S NRP-Z2 for connection to the sensor connector.
This six-pole connection provides the external trigger capability.
–
Standard USB cable (USB type A to USB type B) to any USB type A connector
of the R&S
AREG100A. This connection does not support external triggering.
●
Connection via USB hub with external power supply unit
Requires the following cables, depending on the used sensor type:
–
R&S NRP-ZKU (USB interface cable) for R&S NRPxx power sensors
–
R&S NRP-Z3 or R&S NRP-Z4 (USB adapter cables) for sensors of the R&S
NRP-Zxx family
●
Connection via LAN for R&S
NRPxxxSN power sensors
Using the Ethernet interface requires PoE (Power over Ethernet) to provide the
electrical power.
To establish the connection, you can use:
–
A PoE Ethernet switch, e.g. R&S NRP-ZAP1 and an RJ-45 Ethernet cable.
–
A PoE injector and an RJ-45 Ethernet cable.
Detection and mapping
The R&S
AREG100A automatically detects a connected R&S NRP power sensor and
indicates it in the "NRP Power Viewer" and "NRP Sensor Mapping" dialogs.
By default, detected sensors are indicated as follows:
●
A sensor connected at the Sensor socket is assigned as "Sensor 1".
If no sensor is connected to this socket, channel 1 remains unassigned.
●
Sensors 2 to 4 are assigned to the sensors at the USB connectors, according to
their sequence of connection.
On connection, the R&S
AREG100A immediately starts the measurement of a detec-
ted R&S NRP power sensor. If you perform an instrument preset ([Preset] key or
*RST
), the R&S
AREG100A stops the measurements. The connection and the map-
ping of the power sensors remain, the measurements must be restarted.

NRP Sensor Mapping
The "NRP Sensor Mapping" lists all R&S NRP sensors detected by the instrument.
