HP/Agilent 8481D Diode Power Sensor, 10 MHz to 18 GHz

The Agilent 8481D diode power sensor is designed for use with the EPM series, EPM-P series, 70100A, E1416A and the discontinued 43x power meters, and provides extraordinary accuracy and stability. The 8481D high-sensitivity power sensor measures the average power over its entire -70 to -20 dBm dynamic range which gives you accurate readings even if your test signal is subjected to multi-tone environments, modulated carriers, or carriers with high harmonics. You also get extremely low SWR and it’s traceable to the U.S. National Institute of Standards and Technology (NIST).
