The pre-owned Agilent E4440A PSA combines laboratory-grade dynamic range with 3 Hz-to-26.5 GHz coverage and up to 80 MHz instantaneous bandwidth, letting engineers capture wide 5G NR, radar or sat-com bursts in a single sweep.
A –118 dBc/Hz phase-noise floor and –155 dBm/Hz noise level reveal low-level spurs without external LNAs, while 0.19 dB amplitude accuracy and SCPI/LAN automation keep compliance tests precise and repeatable.
Buying refurbished slashes capital expense and lead-time; units can ship ISO-17025-calibrated with the latest PSA firmware, preserving Agilent reliability, option upgradeability and long-term serviceability at a fraction of new-instrument cost.
