Keysight N9000B — 9 kHz–26.5 GHz Multi-Touch CXA RF Spectrum Analyzer

The pre-owned Keysight N9000B delivers essential signal and spectrum analysis to 26.5 GHz in a compact 4-U package. Its multi-touch UI speeds everyday RF tasks, while the 10 MHz (25 MHz optional) digitizer bandwidth and -110 dBc/Hz phase-noise floor provide confidence in compliance and manufacturing measurements. With the built-in preamp engaged, a -163 dBm/Hz DANL reveals low-level emissions without external LNAs. Buying used cuts capital expense and lead-time; units can ship with fresh ISO-17025 calibration and the latest 2024 firmware, preserving Keysight reliability at a fraction of new-instrument cost.

Every unit is calibrated at an ISO/IEC 17025 accredited laboratory. The original calibration certificate, marked TESTRO Certified, is linked to the unit's serial number and included in the shipment.
