Any high-precision power measurement application, for instance level calibration, requires very high accuracy to measure and align transmitting power. When equipped with the R&S NRPxx power sensors and the R&S ZNH-K9 option, the ZNH becomes an accurate RF power meter with a wide measurement range. Calibration is not required prior to making measurements since the sensors are fully characterized over frequency, level, and temperature and feature long-term stability. Zeroing is usually not required; the user can plug in a sensor and simply start measuring.
The R&S FSH-Z14 and FSH-Z44 directional power sensors transform the ZNH into a full-featured directional power meter. The R&S ZNH can then simultaneously measure the output power and the matching of transmitter system antennas under operating conditions. The power sensors measure average power up to 120 W and eliminate the need for extra attenuators. In addition, the peak envelope power (PEP) can be determined up to 300 W. A common application is the combined monitoring of the transmitter output and antenna reflected power of critical systems.
Power measurements may also include optical power measurements. Testing optical transport networks (OTN) during base station installation and maintenance is a prime example. The R&S HA-Z360/-Z361 optical power meters connect to the R&S ZNH USB port and visualize optical absolute power in dBm as well as relative power in dB on the instrument.
