Rohde & Schwarz R&S NRP-Z58 coaxial power sensor

The R&S NRP-Z58 coaxial power sensor from Rohde & Schwarz is claimed to be the first to measure power in the frequency range from DC to 110 GHz.

Users working with a frequency range above 67 GHz now also benefit from the unique features of the thermal power sensors from Rohde & Schwarz.

Rohde & Schwarz says the sensor’s high measuring speed of over 300 measurements/s in buffered mode allows especially fast power measurements. With a range of 55 dB (-35 to 20 dBm), it is claimed to provide the largest dynamic range (DC to 110 GHz) of any thermal power sensor on the market.

When performing relative measurements such as amplification and reflection measurements, the NRP-Z58 delivers precise measurement results due to its high linearity of 0.01 dB. The ball bearing 1.00 mm coaxial plug can be screwed conveniently and securely onto the jack of the measuring instrument to provide high measurement reproducibility.

The NRP-Z58 can be connected directly to a PC via a USB interface in order to analyse measurement results. It can also be used in combination with the R&S NRP2 base unit or with nearly any signal generator, signal and spectrum analyser or network analyser from Rohde & Schwarz.

For users of the R&S ZVA110 network analyser, the power sensor is a suitable addition. It comes equipped with the appropriate 1 mm socket for connecting the NRP-Z58. The power sensor makes it possible to achieve a consistent power calibration up to 110 GHz using a single instrument and without any adapter. Before, this required multiple power sensors and various adapters.

In addition, the power sensor helps users working in development, production and maintenance to determine the average power of CW signals, pulsed signals or even complex digitally modulated signals. This makes the sensor suitable for automotive applications at 77 GHz, such as automatic cruise control and collision warnings, as well as for radar systems for industrial and military applications at 94 GHz.
