Technical Information
Power Sensors R&S NRP-Z22, -Z23, -Z24
The right choice for medium-power applications
These power sensors with nominal powers of 2 W
(R&S NRP-Z22), 15 W (R&S NRP-Z23) and 30 W
(R&S NRP-Z24) expand the measurement capabili-
ties of the R&S NRP family in the frequency range
from 10 MHz to 18 GHz. They allow direct power
radio equipment or digital mobile radio base sta-
tions. Tried-and-tested precision attenuators ahead
of the power sensor ensure high measurement
accuracy and excellent stability of the electrical
characteristics. The new products are of great
benefit, since they provide full accuracy even if they
are used without an attenuator being connected. In
this case, they behave like a standard R&S
NRP-Z21 sensor with a nominal power of 200 mW
and a lower measurement threshold of 200 pW
(-67 dBm). The full functionality of this sensor type
– including 90 dB dynamic range, suitability for
modulated signals, time gating, etc – is available in
every operating mode, i.e. also with adapted at-
tenuator.

Specifications
Specifications apply when the power sensor is operated together with the supplied power attenuator (pad). Please refer to the specifications of the R&S NRP-Z21 in the R&S NRP data sheet (PD 0757.7023.21) when operating the power sensor alone.
Bold: Parameter 100% tested
Italics: Uncertainties calculated from the test assembly specifications and the modelled behaviour of the sensor.
Normal: Compliance with specifications is ensured by the design or derived from the measurement of related parameters

Footnotes
Please refer to the R&S NRP data sheet for footnotes not mentioned below. Please keep in mind that the power levels specified there are valid only for the power sensor section. Add +10 dB in the case of the R&S NRP-Z22, +20 dB in the case of the R&S NRP-Z23 or +25 dB in the case of the R&S NRP-Z24 to calculate the power inci­dent on the pad preceding the sensor.
