Check the listing for details. HP / Keysight 432A Power Meter with 478A Thermistor Mount & Cable. Condition: Seller refurbished. Listed at 495.00 USD. 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 HP 478A provides high efficiency and good radio frequency (RF) match. Used in conjunction with the 432-series power meters it provide high accuracy even in routine power measurements. The thermistor mount is temperature compensated for low drift, even in the presence of thermal shocks, permitting measurement of microwave power as low as one microwatt High accuracy even in routine power measurements Temperature compensated for low drift Measures microwave power as low as one microwatt Shows calibration factor and effective efficiency at 12 frequencies Frequency Range: 10 MHz to 10 GHz Maximum SWR: 10 MHz to 25 MHz 1.75; 25 MHz to 7GHz 1.30; 7 GHz to 10 GHz 1.50 RF Connector is type N(m) 8120-1082 5-foot Power Meter Cable for 432-series432A Manual available at https://www.nousnexus.com/Manuals/Agilent_HP_432A.pdf478A Manual available at https://www.keysight.com/us/en/assets/9018-04911/user-manuals/9018-04911.pdf The items are in good condition, tested and working.
