NRP6AN EMC Average Power Sensor For USB and LAN operation
Power measurement range: 100 pW to 200 mW, Frequency range: 8 kHz to 6 GHz, Level Range: -70 dBm to 23 dBm, Connector: N Type Male
Specially designed for EMC applications
In EMC applications, usually only the average power is of interest. This is where the NRPxxA(N) average power sensors are the perfect fit. They cover measurement ranges that are used in telecommunications as well as the important lower frequency bands down to 8 kHz. Users benefit from the excellent properties of the three-path diode power sensors, including a dynamic range of up to 93 dB, very low influence of the modulation on the measurement and outstanding impedance matching.
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 NRPxxT(N)/TWG 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 sophisticated measurement cell of the NRPxxT(N)/TWG thermal power sensors quickly attains a stable temperature. When the power level is decreased, the excess heat is dissipated extremely quickly. Consequently, thermal power sensors from Rohde & Schwarz are able to measure three times faster than comparable solutions on the market with triggered measurements and > 500 measurements/s in buffered mode – with top accuracy.
The NRPxxT(N) 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. The NRPxxTWG thermal power sensors feature a linearity of 0.010 dB (0.23%) between 50 GHz and 110 GHz – the ideal choice for performing relative measurements. These sensor characteristics are particularly beneficial in reference applications and calibration labs.
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 NRP family are excellently matched up to high frequencies, reducing measurement uncertainty.
Sophisticated coaxial connector concept
Thanks to the innovative connector design, the sensors 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 NRPxxT(N)/TWG 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 to the value stored during the previous calibration. The result provides information about the functionality and accuracy of the power sensor.
