HP 8485D High Sensitivity Diode Power Sensor, 50 MHz to 26.5 GHz

Product Summary

The HP 8485D 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 8485D 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 at mm-wave frequencies, and it's traceable to the U.S. National Institute of Standards and Technology (NIST). A 50 MHz calibration port is included with the power sensor for calibration with the power meter. This calibration provides traceability to NIST at millimeter-wave frequencies, 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

• 50 MHz calibration port

• Accurate calibration and traceability to NIST millimeter-wave sensor calibration

• Accessories included for accuracy optimization and customer convenience
