Keysight N8480 Series Power Sensors are the replacement solutions for 8480 Series Power Sensors. The new power sensors are integrated with EEPROM feature, which allows users to calibrate the power sensors without manually entering the calibration factors to the power meter. By comparing to legacy 8480 Series Power Sensors, there are tremendous improvements such as wider dynamic range and frequency range, better accuracy, linearity, repeatability, and SWR.
