N1921A 50 MHz – 18 GHz P-Series WB Power Sensor (-35 to +20 dBm)

The Keysight (Agilent) N1921A P-Series wideband power sensor 50 MHz to 18 GHz, provides internal zero and calibration, by integrating a DC reference source and switching circuits into the power sensor. This feature of the N1921A eliminates the multiple connections associated, by using an external calibration source, thus minimizing connector wear, test-time and measurement uncertainty.
Keysight (Agilent) N1921A – Features and Specifications:
Wide dynamic range-35 dBm to 20 dBm for peak power measurements
Precision Type-N connector as standard
EEPROM stores calibration factors, linearity, temperature and bandwidth correction data
Zero and calibrate while connected to the device under test (DUT)
Sensor cable fixed to sensor
