產品詳細介紹Product Introduction

Ideal for universal applications
Three-path diode power sensors are suitable for numerous applications since they support continuous average, burst average, timeslot average, gate average and trace measurements. Featuring outstanding performance and unprecedented measurement speed and accuracy, the sensors can be used to perform precise average power measurements on wireless signals ranging from GSM and LTE up to 5G NR. For detailed analysis, the sensors offer additional measurement functions such as timeslot mode and trace mode with a video bandwidth of 100 kHz.

Offering a frequency range of up to 33 GHz, the R&S®NRP33S(N) is ideal for use in the automotive sector, for example in the development and production of longrange and short-range anti-collision radars (24 GHz). It is also a perfect choice for installation, maintenance and remote monitoring of ground stations for satellite systems (up to 33 GHz).

The R&S®NRP40S(N) and R&S®NRP50S(N) are ideal for measurements on microwave link systems operating at frequencies up to 50 GHz. The user benefits from short measurement times and the sensors’ wide dynamic range.

The R&S®NRP67S(N) supports frequencies up to 67 GHz including IEEE802.11ad and IEEE802.11ay.

93 dB dynamic range thanks to improved three-path concept
The R&S®NRPxxS(N) 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 irrespective of the modulation type. Measurement results are hardly affected by interfering signals or harmonics. The R&S®NRPxxS(N) power sensors therefore behave 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.

Unlike conventional multipath technology, adjacent diode paths in the R&S®NRPxxS(N) power sensors overlap by 6 dB. All paths are continuously and simultaneously measured. The final measurement result is achieved by appropriately weighting the measurement results of all paths. This innovative approach ensures a smooth transition between measurement paths. Problems due to hard switching between the measurement paths, such as hysteresis effects, additional measurement delays and differential nonlinearity, are eliminated. The patented sensor architecture also improves the signal-to-noise ratio and increases measurement speed in the transition region.

Unprecedented measurement speed and accuracy even at low levels
The measurement speed is not only a function of the sampling rate. It depends to a substantial degree on the level to be measured and the desired measurement accuracy. To increase measurement accuracy, especially at low levels, it is necessary to average multiple measured values. While averaging reduces the noise component and thus increases measurement accuracy, it also slows down the measurement. The R&S®NRPxxS(N) power sensors have therefore been designed with an extremely low measurement noise in mind.

As a basic rule, it can be said that a 50% reduction in the measurement noise will reduce the measurement time by a factor of four while maintaining the same accuracy.

With a typical measurement noise of 20 pW, the R&S®NRPxxS(N) power sensors can perform measurements down to a lower limit of –70 dBm with the highest speed and accuracy currently available on the market.

More than 50 000 readings/s
With more than 50000 readings/s in fast continuous average mode, the R&S®NRPxxS(N) power sensors are currently the fastest sensors on the market. In buffered mode, they can transmit up to 8192 measured values per block with a minimum aperture of 10 µs. This corresponds to a continuous acquisition time of 81.92 ms. Any sporadic interference will be reliably detected.
