R&S®NRP40T Thermal Power Sensor

300 nW to 100 mW, DC to 40 GHz

Key facts

  • Measurement range: -35 dBm to +20 dBm
  • Frequency range: DC to 40 GHz
  • Outstanding performance for reference applications
  • 2.92 mm connector
  • Outstanding linearity of 0.007 dB (0.16 %)

Brief description

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®NRP40T thermal power sensors is designed to reduce measurement noise to a minimum and to make the sensor immune to thermal environmental effects.
