category: power meter + power sensor
keysight n432a is the replacement for keysight’s legacy 432a analog thermistor power meter. the single-channel, average rf power meter operates with the keysight 8478b and 478a thermistor mounts. the n432a-and-thermistor-mount pair is ideal for applications that require high measurement accuracy, particularly in metrology and calibration laboratory environments. the enhanced thermistor power meter comes with a digital color lcd display, and user-friendly front panel interface. its built-in calibration factor table provides a more convenient and accurate method of storing calibration factors as compared to the old knob-turning approach of the 432a. the n432a is lxi compliant, and programmable via gpib, usb and lan.
