Descrição
Thermal power sensors are especially used for complex measurement tasks. They feature higher accuracy and tolerate any type of modulation.

To improve measurement accuracy, the hardware of the R&S®NRP-Z5x thermal power sensors is designed to reduce measurement noise to a minimum and to make the sensor immune to thermal environmental effects. These sensor characteristics are particularly beneficial in reference applications and calibration labs.

Key Facts
• Measurement range: -35 dBm to +20 dBm
• Frequency range: DC to 40 GHz
• 2.92 mm connector
• Operation with R&S®NRP2 base unit or via USB on a Laptop/PC
• Outstanding linearity of 0.007 dB (0.16%)    
• Industry-proven DC-coupled thermoelectric test cell
• Best SWR at 40 GHz (1.25)
• Sophisticated connector design
• Excellent impedance matching

Features & Benefits
Outstanding performance for reference applications
Thermal power sensors are especially used for complex measurement tasks where highest accuracy counts. They tolerate any type of modulation.
To improve measurement accuracy, the hardware of the R&S®NRP-Z5x thermal power sensors is designed to reduce measurement noise to a minimum and to make the sensor immune to thermal environmental effects.

To achieve stable measurement results, the temperature in the thermal test cell must correspond to the applied power. When the power is increased, the measurement cell of the R&S®NRP-Z5x thermal power sensors quickly attains a stable temperature. When the power level is decreased, the excess heat is dissipated extremely quickly. Thermal power sensors from Rohde & Schwarz are able to measure three times faster than comparable solutions on the market - with top accuracy.

The R&S®NRP-Z5x thermal power sensors feature an unparalleled linearity of 0.007 dB (0.16 %) up to 67 GHz and 0.010 dB (0.23 %) between 67 GHz and 110 GHz, making them the ideal choice for performing relative measurements.

These sensor characteristics are particularly beneficial in reference applications and calibration labs.
R&S®NRP-Z55 Thermal Power Sensor model .03 Features & Benefits

Excellent impedance matching
To a large extent, measurement uncertainty results from multiple reflections at the source and power sensor caused by mismatch. To minimize these reflections, all thermal power sensors in the R&S®NRP family are excellently matched up to high frequencies, reducing measurement uncertainty.

Sophisticated connector concept

Thanks to the innovative connector design, the sensor can be easily screw-connected to the signal source to be measured. A ball bearing in the coupling nut ensures that only the coupling nut has to be turned to tighten the sensor. The sensor body stays fixed in the required position. Contrary to conventional connecting screws, the outer conductors of the sensor and DUT are not turned relative to each other and so their mating surfaces do not rub together. This reduces wear and enhances reproducibility of measurements. The connector concept contributes to high measurement accuracy.

Internal calibration test
Rohde & Schwarz has implemented a special verification function in the R&S®NRP-Z52/R&S®NRP-Z55/R&S®NRP-Z56/R&S®NRP-Z57/R&S®NRP-Z58 sensors. This function covers all essential components of the signal path. Using a test routine, the sensor’s response to a highly stable applied DC power is measured and compared against the value stored during the previous calibration. The result provides information about the functionality and accuracy of the power sensor. Two additional advantages: The power sensor can remain on site during verification, and verification can even be performed while another measurement is carried out.

Supported Devices
The R&S®NRP-Z55 sensor can be connected to latest-generation of signal generators, spectrum analyzers and network analyzers. This allows you to directly display the average power measured with the sensor without the need for an R&S®NRP2 base unit or PC. This also provides a simple solution for automatic level correction in a signal generator. The spectrum analyzers use the measured power as an absolute reference for increasing the measurement accuracy.
