– 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 SMB100B. 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/xxxTN/xxxAN 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 SMB100B automatically detects a connected R&S NRP power sensor and
indicates it in the "NRP Power Viewer" and "NRP Sensor Mapping" dialogs.
By default, sensors 1 to 4 are assigned to the sensors at the USB connectors, accord-
ing to their sequence of connection.
You can change the default mapping in the NRP sensor mapping dialog.
On connection, the R&S SMB100B immediately starts the measurement of a detected
R&S NRP power sensor. If you perform an instrument preset ([Preset] key or *RST),
the R&S SMB100B stops the measurements. The connection and the mapping of the
power sensors remain, the measurements must be restarted.
7.4.2 NRP sensor mapping
The "NRP Sensor Mapping" lists all R&S NRP sensors detected by the instrument.
