The pre-owned Keysight N9040B UXA delivers laboratory-class spectrum and vector-signal analysis from 2 Hz to 50 GHz in one touchscreen platform, with plug-on heads pushing coverage to 110 GHz for 5G FR2 and V-band radar. Optional 1 GHz capture bandwidth lets engineers verify ultra-wideband chirps, satellite bursts and Wi-Fi 7 waveforms in a single sweep, while a –136 dBc/Hz phase-noise floor and –174 dBm sensitivity reveal spurs that threaten tight EVM and ACLR limits.
Real-time 510 MHz analysis guarantees 100 % probability-of-intercept for micro-second transients, and 10 GbE streaming plus SCPI scripting accelerate automated production lines. Supplied fully tested, freshly calibrated and firmware-current, each unit ships from stock—delivering Keysight precision, reliability and long-term serviceability at a fraction of new-instrument cost.
