HP 8480 Power Sensor Family

The HP 8480 power sensors are designed for use with the HP EPM series, 435B, 436A, 437B, 438A, 70100A, and E1416A power meters. These thermocouple and diode power sensors provide extraordinary accuracy, stability, and SWR over a wide range of frequencies and power levels. The HP 8480 power sensor family gives you extremely low SWR even at millimeter-wave frequencies. This low SWR translates into minimum mismatch uncertainty and optimum measurement accuracy. Each power sensor in the HP 8480 family is individually calibrated and traceable to the U.S. National Institute of Standards and Technology. A 50 MHz calibration port is included in HP waveguide power sensors for calibration with the power meter. This calibration eliminates the uncertainties due to temperature changes and the variance in making measurements with different meter/sensor combinations.
