The ¸NRP family Accurate determination of RF power is one of the most challenging tasks in the field of electrical test and measurement. No matter whether an application involves characterizing the RF components used in mobile communications equipment, for example, or assessing the transmit power of complex radar systems, base stations or mobile telephones, there is always a need to measure RF power as accurately as possible. This includes applications in R & D, production and maintenance as well as in calibration laboratories. The ¸NRP family is ideal for such applications. In addition to the...

With its ruggedized but compact design, battery supply option (R&S®NRP-B3) and low weight, the R&S®NRP is opti- mally suited for laboratory and produc- tion applications as well as mobile use. The clear menu structures and window- based operating concept make...

Connectivity Display of measured values Simultaneous measurements are p ­ ossible on up to four different measurement points by connecting up to four sensors (depending on the option). A trigger input also allows externally triggered, synchronous measurements. Two BNC outputs are available for status indication (e.g. limit monitoring). The E ­ thernet (¸NRP-B4), GPIB and USB remote-control interfaces ensure optimized integration into automated test setups. An optional sensor check source is useful for fast verification of the sensors (¸NRP-B1). Calibration of the sensors immediately prior to...

Intelligent sensors for every need All of the sensors of the ¸NRP family function as independent measurement instruments due to their integrated signal processing. The measured values undergo complete processing in the sensor and are output in digital format. Any additional error sources such as interference acting on the sensor's connecting cable or due to the base unit itself are consistently eliminated in the ¸NRP family owing to digital data transfer via USB. For the entire range of sensors, the ¸Smart Sensor TechnologyTM e ­ nsures top accuracy, repeatability and usability. General sensor...

Accurate measurement of TDMA-based signals The analysis of the TDMA-based signals encountered in GSM/EDGE, DECT and PDC, for example, is a common appli- cation for state-of-the-art power mea- sensors are very powerful tools for such work. The trace mode makes graphical analysis of any signal very straightfor- ward. The ability to easily modify the time axis plus the auto-scaling function provide useful support during in-depth analysis of relevant signal components. The special timeslot function allows simultaneous analysis of multiple equi- distant timeslots. Up to four timeslots the R&S®NRP...
