Highlights

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

The Keysight N432A is the replacement for Keysight’s legacy 432A analog thermistor power meter. This single-channel average RF power meter operates with the Keysight 8478B and 478A thermistor mounts, making it ideal for applications demanding high measurement accuracy, especially in metrology and calibration laboratories.

The enhanced N432A features a digital color LCD and a user-friendly front panel interface. It's built-in calibration factor table offers a more convenient and precise method for storing calibration factors, replacing the manual knob-turning process of the 432A. The N432A is LXI compliant and fully programmable via GPIB, USB, and LAN interfaces.
