HP / Keysight 432A Power Meter with 8478B Thermistor Mount & Cable

• The HP / Keysight 432A Analog Power Meter provides high accuracy over a wide temperature range. By measuring the output voltage of the thermistor bridges and computing the corresponding power, even higher accuracy of ±0.2 percent ±0.5 µW can be obtained with the 432A. Accuracy can be maintained on even the most sensitive range because the error due to thermoelectric effect is reduced to a negligible level.

• The Keysight 8478B provides high efficiency and good radio frequency (RF) match. Used in conjunction with the N432A or 432A power meters 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 (NIST) at those frequencies where NIST provides calibration service.
