N432A/-008

N432A/-008 is a PM3-class thermistor power meter with 008 option (thermistor sensor adaptor cable 5ft (1.5m)). It is an automatic, self-balancing power meter for use with temperature-compensated thermistor mount sensors. The N432A replaces the legacy 432A analogue power meter, with enhanced performance and features. 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 colour LCD and a user-friendly front panel interface. It is 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.

• Frequency range from 100kHz to 18GHz (sensor dependent)
• Power range from –30dBm (1μW) to +10dBm (10mW)
• High accuracy (≤ 0.1% ±0.5uW), excellent for 1mW 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 ohm)
• Dimension is 212.6mm W x 88.5mm H x 348.3mm D (8.5" x 3.5" x 13.7")
