The pre-owned Agilent E4419A integrates two high-speed average-power channels with a 1 ppm OCXO time base, delivering accurate measurements from 100 kHz to 110 GHz across a wide –70 dBm to +44 dBm span. Simultaneous dual-sensor operation halves setup time for gain, compression or VSWR checks, and real-time ratio/delta math eliminates spreadsheet post-processing. Up to 200 corrected readings per second keep production lines moving, while EEPROM autoloading of calibration factors from E- and 8480-series sensors reduces uncertainty and user error. GPIB and RS-232 interfaces plus SCPI syntax drop straight into legacy 438A code or modern ATE scripts. Refurbished units ship ISO-17025-calibrated with current firmware, giving you Keysight-grade accuracy, sensor backward-compatibility and long-term serviceability at a fraction of new-instrument cost.
