The R&S NRPxxT(N) thermal power sensors feature 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 suitable for performing relative measurements.

The thermal power sensors are used for complex measurement tasks where high accuracy is critical. They also tolerate any type of modulation. To improve measurement accuracy, the hardware 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 thermal power sensors quickly attains a stable temperature.

When the power level is decreased, the excess heat is dissipated extremely quickly. The company claims its thermal power sensors are able to measure with accuracy three times faster than comparable solutions with triggered measurements and >500 measurements in buffered mode.

The power sensors are designed to operate with the power meter base unit or a PC/laptop. They also offer USB capability and can be additionally controlled via LAN.
