HP 8478B Coaxial Thermistor Mount, 10 MHz to 18 GHz

Product Summary

High efficiency and good radio frequency (RF) match are characteristic of the HP 8478B coaxial thermistor mounts. Used in conjunction with the HP 432A power meter they provide high accuracy even in routine power measurements. These thermistor mounts are temperature compensated for low drift, even in the presence of thermal shocks, permitting measurement of microwave power as low as one microwatt. Each mount contains data showing calibration factor and effective efficiency at six frequencies, directly traceable to the U.S. National Institute Standards and Technology at those frequencies where NIST provides calibration service.
