Fast, accurate and packed with features to measure

CW and modulated signals

The R&S®NRPxxS/SN power sensors use three separate diode paths, each operated in the optimum detector range. As a result, the average power can be determined with high accuracy independent of the modulation type. Measurement results are hardly affected by interfering signals or harmonics. The R&S®NRPxxS/SN power sensors therefore behave in a way similar to thermal power sensors but offer significantly higher speed. They provide up to 93 dB dynamic range with an excellent lower measurement limit of –70 dBm.

Features & benefits

The universal power sensor

Ideal solution for many applications

Three-path diode power sensors are suitable for numerous applications, since they support continuousaverage, burst average, timeslot average, gate average and trace measurements. Featuring outstandingperformance and unprecedented measurement speed and accuracy, the sensors can be used toperform precise average power measurements on wireless signals such as GSM and 3GPP as well ason higher bandwidth signals such as LTE,LTE-Advanced or 5G.

93 dB dynamic range

Improved thre-path concept

The R&S@NRPxxS(N) power sensors use three separate diode paths, each operated in the optimumdetector range. The average power can be determined with high accuracy irrespective of themodulation type. Measurement results are hardly affected by interfering signals or harmonics. TheR&S@NRPxxS(N) power sensors therefore behave similar to thermal power sensors but offer significantlyhigher speed and up to 93 dB dynamic range.

Unprecedented measurement speed and accuracy

Even at low levels down to -70 dBm

To increase measurement accuracy at low levels, it is necessary to average multiple measured values.While averaging reduces the noise component, it also slows down the measurement. TheR&S@NRPxxS(N) power sensors have therefore been designed with an extremely low measurementnoisein mind.

The R&S@NRPxxS(N) power sensors can perform measurements down to a lower limit of -70 dBm withthe highest speed and accuracy currently available on the market.

New fast mode

Unlimited time measurement with up to 100.000 measurements/s

In fast continuous average mode, the R&SeNRPxxS(N) power sensors can perform up to 100,000triggered measurements/s with a minimum trigger repetition time of 100 us without losing anymeasurement. This measurement speed is achieved by using the buffered mode. In buffered mode, almeasured data is collected inside the sensor and transmitted in one block to the sensor's host. TheR&SeNRPxxS(N) sensors perform the new fast mode without time limitation!

Sensors for high-power applications

Perform power measurements up to 30 W

The R&SeNRP18S-10,R&SNRP18S-20 and R&SeNRP18S-25 high-power three-path diode powersensors consist of an R&SeNRP18S and a 10/20/25 dB upstream attenuator, They are able to performpower measurements up to 2 W, 15 W and 30 W. When used with the attenuator. mismatch errorsbetween the sensor and attenuator are automatically corrected. The S-parameters for the attenuator aredetermined and stored in the sensor during production.

TVAC-compliant three-path diode power sensor

Specially designed for use in thermal vacuum (TVAC) chambers

The R&S@NRPxxSN-VTVAC-compliant power sensor is designed for satellite communicationsapplications in a frequency range up to 67 GHz. All components are baked in a vacuum chamber duringthe production process, so outgassing is reduced to a minimum. Thanks to their LAN capability, thepower sensors can be easily controlled and monitored from outside the chamber while the ventingholes in the housing ensure pressure equalization.
