The pre-owned Agilent E4407B delivers laboratory-grade spectrum analysis up to 26.5 GHz in a rugged 4-U chassis weighing just 17 kg. Its digitally synthesized RBWs reach 1 Hz (with 1DR/1D5), and a –101 dBc/Hz phase-noise floor keeps adjacent-channel measurements clean. With the internal 20 dB pre-amp engaged, a –167 dBm/Hz DANL reveals low-level emissions without an external LNA, while the standard 10 MHz analysis bandwidth and optional tracking generator support EMI, radar, and 5 G NR FR1 sweeps.

Buying refurbished slashes capital expense and lead-time; units can ship ISO-17025-calibrated and firmware-verified, preserving Agilent accuracy and SCPI automation at a fraction of new-instrument cost.
