HIGHLIGHTS

  • Frequency range: 100 kHz to 18 GHz (sensor dependent)
  • Dynamic range: -30 dBm to +10 dBm
  • High Accuracy (≤ 0.1% ± 0.5 uW), excellent for 1 mW transfer calibration (with 478A-H75/H76)
  • Built-in 6.5 digits ADC eliminates the need for external DMM
  • Selectable bridge resistance (100/200/300/400 Ω)
  • Remote interface flexibility (GPIB, USB, LXI-C)
  • Digital color LCD display

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, and a 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.
