Description
Product Overview
Keysight positions the N8481A as a thermocouple average power sensor for RF and microwave power measurement. It is part of the N8480 Series Thermocouple Power Sensors. Model-specific evidence confirms frequency range: 10 MHz to 18 GHz, average power range: −35 to +20 dBm, RF interface: Type-N male connector, sensing technology: Thermocouple/True Average Power, and standard calibration data: EEPROM autoload, supporting engineering work such as wireless device characterization and calibration and production testing. Exact options, interfaces, accessories, calibration scope, and regional availability depend on the ordered configuration and should be confirmed before purchase.
