Keysight / Agilent N432A Power Meter
The Agilent N432A Power Meter is a sophisticated and highly accurate tool designed for precise RF power measurements. As a modern replacement for the legacy 432A analog thermistor power meter, the N432A offers a single-channel average RF power measurement specifically engineered to support the Agilent 8478B and 478A thermistor mounts. This pairing is ideal for demanding applications in metrology and calibration labs, where measurement accuracy is paramount.
Key Features and Specifications
- Frequency Range: 100 kHz to 18 GHz (sensor dependent)
- Dynamic Range: -30 dBm to +10 dBm
- High Accuracy: ≤ 0.1% ± 0.5 µW, excellent for 1 mW transfer calibration (with 478A-H75/H76)
- Integrated 6.5 Digit ADC: Eliminates the need for an external digital multimeter (DMM)
- Bridge Resistance Selection: Choose between 100, 200, 300, or 400 Ω
- Remote Interface: Flexible connectivity options with GPIB, USB, and LXI-C
- User-Friendly Display: Digital color LCD for clear data visualization
The N432A’s built-in calibration factor table streamlines the calibration process, providing a more efficient and accurate method for storing calibration data compared to traditional knob-turning methods. Designed with ease-of-use in mind, the intuitive front panel interface allows users to operate the device with minimal training.
