The pre-owned Agilent E4404B ESA-E brings reliable 9 kHz–6.7 GHz coverage to service benches and production lines in a single 4-U chassis. Its standard 1 kHz–5 MHz RBWs (expandable to 100 Hz with option 1DR) and –101 dBc/Hz phase-noise floor let engineers separate closely spaced carriers, while the internal pre-amplifier pushes DANL to –167 dBm/Hz—quiet enough to “hear a pin drop” in RF terms. SCPI/IVI control, optional measurement personalities, and LAN/GPIB interfaces keep automation simple.
Buying refurbished cuts capital expense and lead-time; units can ship ISO-17025-calibrated with the latest firmware, preserving Agilent precision and long-term serviceability.
