Total absolute amplitude accuracy is ±0.40 dB at 50 MHz reference. RBW resolves from 1 Hz to 8 MHz and the analyzer captures up to 100,001 sweep points per trace. UTS5026A is built around three pillars: frequency reach through the K-band ceiling at 26.5 GHz, covering all sub-6 GHz cellular and Wi-Fi bands plus 5G mmWave-adjacent spectrum, SATCOM downlinks, and microwave point-to-point links; a quiet front end with -163 dBm/Hz typical DANL (P26 option) and -107 dBc/Hz typical phase noise that resolves low-level spurs and characterizes oscillator skirts cleanly; and a modular measurement library covering vector signal demodulation, I/Q capture, EMI pre-compliance, 5G NR and LTE air-interface decoding, dedicated phase-noise measurement, and analog AM/FM demodulation — each available as a no-expiration license unlock. Engineered for RF and microwave design teams, EMC pre-compliance benches, cellular and SATCOM development groups, and private-sector test labs. Key Features 9 kHz to 26.5 GHz spectrum measurement — covers sub-6 GHz, K-band, and microwave point-to-point bands in one instrument DANL: -163 dBm/Hz typical (with UTS5000A-P26 preamp option, 20 MHz to 1.5 GHz, 1 Hz RBW); -150 dBm/Hz typical baseline (preamp off) Phase noise: -107 dBc/Hz typical at 1 GHz, 10 kHz offset Total absolute amplitude accuracy: ±0.40 dB at 50 MHz reference RBW: 1 Hz to 3 MHz in 10% steps, plus 4, 5, 6, 8 MHz wide-band settings; selectivity 50 acquisitions). For RF designers characterizing PLL synthesizers, VCOs, and crystal oscillators, that envelope means close-in noise sidebands on the device under test sit above the analyzer’s own contribution rather than buried beneath it. The UTS5000A-PNM Phase Noise Measurement option adds a dedicated measurement mode with logarithmic offset axes, jitter calculation, and integration limits. Nominal phase noise at 1 GHz center frequency: -100 dBc/Hz at 1 kHz offset, -107 dBc/Hz at 10 kHz offset, -132 dBc/Hz at 1 MHz offset (typical). × Nominal phase noise at 1 GHz center frequency: -100 dBc/Hz at 1 kHz offset, -107 dBc/Hz at 10 kHz offset, -132 dBc/Hz at 1 MHz offset (typical). RBW Resolution and Selectivity (1 Hz to 8 MHz) RBW: 1 Hz to 3 MHz in 10% steps, plus 4, 5, 6, and 8 MHz wide-band settings. Resolution Bandwidth selects from 1 Hz to 3 MHz in 10% steps (the standard 10:1 ratio family used across professional spectrum analyzers), plus dedicated 4, 5, 6, and 8 MHz wide-band settings for fast sweeps over wide spans. Bandwidth accuracy is ±1.0% (±0.044 dB) nominal from 1 Hz to 750 kHz. Selectivity (the −60 dB to −3 dB shape factor) measures
