7.4 Using Power Sensors
The R&S SMA100B works with most of the R&S NRP power sensors and thus sup-
ports various application tasks. Using power sensors, you can for example determine
attenuation characteristics of downstream equipment or cables. You can use the mea-
sured values to compensate the losses with internal control functions or with an exter-
nal control circuit in real time.
R&S NRP sensors are highly accurate standalone measuring devices, suitable for a
wide range of applications. The devices communicate directly with the signal genera-
tor, calculate the average or peak power internally, include S-parameter correction and
return the measurement results to the generator.
The R&S SMA100B 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.

7.4.1 Connecting R&S NRP Power Sensors to the R&S SMA100B
R&S NRP sensors are connected to the R&S SMA100B in the following ways:
●
Connection to the Sensor connector
– R&S NRP-ZK8 (eight-pole interface cable) for R&S NRPxx power sensors
– 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
