The R&S SMW works with any sensor of the R&S NRP series and can perform up to
four power measurements simultaneously.
Check the firmware version of the R&S NRP sensors regularly. Update the firmware, if
necessary.
For updates, see the Rohde & Schwarz website http://www.rohde-schwarz.com in sec-
tion "Power Meters & Voltmeters".
For more information about working with power sensors, see the following topics:

8.9.4.1 Connecting R&S NRP Power Sensors to the R&S SMW
R&S NRP sensors are connected to the R&S SMW in the following ways:
●
Connection to the SENSOR connector
– R&S NRP-ZK6 (six-pole interface cable) for R&S NRPxx power sensors
– No additional cable for R&S NRP-Zxx power sensors (cable is fixed on the sen-
sor)
●
Connection to the USB connector
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 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 SMW. 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
