Keysight-Agilent N432A

Agilent N432A is the replacement for Agilents legacy 432A analog thermistor power meter. The single-channel average RF power meter operates with the Agilent 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-C compliant and programmable via GPIB USB and LAN.

Key Specifications
