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

Product Summary

The HP 8481D diode power sensor is designed for use with the HP 435B, 436A, 437B, 438A, 70100A, and E1416A power meters and provides extraordinary accuracy and stability. The HP 8481D high-sensitivity power sensor acts as a true-RMS reading device over its entire -70 to -20 dBm dynamic range which gives you accurate readings even if your test signal is subjected to multitone 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). A calibration port is included with the power sensor for calibration with the power meter. This calibration provides traceability to NIST and eliminates the uncertainties due to temperature changes and the variance in making measurements with different meter/sensor combinations.

Product Features

• Excellent SWR for reducing mismatch uncertainty

• Accurate readings with true-RMS reading device

• Accurate calibration and traceability to NIST

• Accessories included for accuracy optimization and customer convenience
