The pre-owned Agilent N5173B MXG sweeps from 9 kHz to 40 GHz while delivering up to +23 dBm and a –122 dBc/Hz phase-noise floor, so it can drive PA compression and still serve as a crystal-clean local oscillator. Its electronic step attenuator provides a 167 dB calibrated span, eliminating external pads for sensitivity or EMC tasks. Built-in AM/FM/PM and pulse modulation plus fast list-mode hopping accelerate automation, and LAN/GPIB SCPI control drops straight into existing code.
Refurbished units ship ISO-17025-calibrated with current firmware, preserving Keysight reliability and future option paths at a fraction of new-instrument cost.
