Thermal Power Sensors -- Rohde & Schwarz

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®NRPxxT(N)/TWG(N) thermal power sensors is designed to reduce measurement noise to a minimum and make the sensor immune to thermal environmental effects. To achieve stable easurement 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 R&S®NRPxxT(N)/TWG(N) 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.
