Keysight (Agilent/HP) N8481A

Keysight's new thermocouple power sensor is a replacement product for legacy 8480 power sensors. It provides more accurate power measurements with excellent power linearity and repeatability. The Keysight N8481A is enhanced with an EEPROM that automatically loads the calibration factors whenever the sensor is connected to the power meter. Option CFT is available as a drop-in replacement for legacy 8480 Series power sensors, preserving manual calibration factor entry and SCPI compatibility. Compatible only with Keysight EPM (E4418B/19B), EPM-P (E4416A/17A), and P-series (N1911A/12A) power meters (a free firmware upgrade may be required). Not compatible with older 400 Series power meters. Features 10 MHz to 18 GHz frequency response Wide dynamic range in a single sensor Built-in EEPROM allows calibration factors to be loaded automatically, eliminating manual input errors (not available with option CFT) High accuracy with excellent power linearity and repeatability Compatible with EPM (N1913A/14A, E4418B/19B), EPM-P (E4416A/17A), P-Series (N1911A/12A) power meters SCPI code compatibility with 8480 series (with option CFT). Option CFT is available as a replacement for legacy 8480 Series power sensors intended for manual cal factor entry and SCPI compatibility. Option CFT is not compatible with 43x and other obsolete power meters. POWER SENSOR 10 MHz - 18 GHz, -30 dBm - +20 dBm (1 µW - 100 mW)
