Overview
The Keysight N9040B UXA X-Series Signal Analyzer is a high-performance, modular RF and microwave signal analysis platform engineered for precision spectral, modulation, and transient characterization of complex wideband signals. Operating on the fundamental principle of superheterodyne downconversion with advanced digital IF processing, the N9040B delivers exceptional frequency coverage from 3 Hz to 26.5 GHz as standard—with extension to 1.1 THz achievable via external harmonic mixing under calibrated conditions. Its architecture integrates a low-phase-noise local oscillator subsystem, high-linearity front-end, and a 510 MHz real-time analysis bandwidth enabled by parallel digital signal processing (DSP) and deep memory acquisition. Designed specifically for demanding applications in aerospace & defense electronic warfare (EW), 5G/6G NR waveform validation, satellite communications, and radar system development, the UXA provides deterministic real-time spectrum capture, high-fidelity I/Q recording, and repeatable scalar/vector measurements traceable to NIST standards.
Key Features
- Standard frequency range: 3 Hz to 26.5 GHz; extendable to 1.1 THz using calibrated external mixers
- Real-time analysis bandwidth up to 510 MHz with 100% probability of intercept (POI) for events ≥ 3.54 µs
- Spurious-free dynamic range (SFDR) > 75 dBc within 510 MHz instantaneous bandwidth
- Ultra-low phase noise: –136 dBc/Hz at 10 kHz offset from a 1 GHz carrier
- 14.1-inch multi-touch capacitive display with intuitive gesture-based UI optimized for lab and field use
- Modular X-Series architecture supporting hardware upgrades (e.g., preselector, ADC resolution, memory depth) and software-defined measurement extensions
- Integrated FPGA-accelerated digital downconverter (DDC) with user-configurable filter shapes and decimation ratios
Sample Compatibility & Compliance
The N9040B supports direct connection to passive and active RF sources including antennas, LNAs, power amplifiers, and signal generators via standard 3.5 mm (f) or 2.4 mm (f) RF interfaces. It complies with international EMC directives (IEC 61326-1:2023, CISPR 11:2024) and safety standards (IEC 61010-1:2010). For regulated environments—including FDA-regulated R&D labs and ISO/IEC 17025-accredited test facilities—the instrument supports audit-ready operation through optional firmware features enabling full measurement traceability, electronic signatures, and 21 CFR Part 11-compliant data integrity controls when used with Keysight PathWave Measurement Manager (PMM) software.
Software & Data Management
The UXA runs on Keysight’s PathWave X-Series Platform firmware, offering native integration with PathWave Vector Signal Analysis (VSA), 5G NR, WLAN, and pulsed-RF application software suites. All measurements support IEEE 1588-2019 Precision Time Protocol (PTP) synchronization for distributed multi-instrument setups. Raw I/Q data is exportable in industry-standard formats (MATLAB .mat, CSV, HDF5, and IQX) with metadata embedded per IEEE Std 1672–2021. Internal SSD storage (up to 2 TB) enables long-duration streaming; external PCIe Gen4 NVMe drives are supported for ultra-high-throughput acquisition. Firmware updates are delivered via secure HTTPS with SHA-256 signature verification and rollback capability.
Applications
- Characterization of wideband radar waveforms (e.g., FMCW, chirp, stepped-frequency) with microsecond-level timing resolution
- 5G NR FR2 and 6G sub-THz component validation, including EVM, ACLR, and spectral emission mask testing
- Electronic warfare signal intelligence (SIGINT) — detection, demodulation, and classification of agile frequency-hopping emitters
- Phase-coherent MIMO channel sounding in over-the-air (OTA) test chambers
- Time-domain analysis of transient interference events in satellite ground station receivers
- Research-grade oscillator stability assessment using Allan deviation and phase noise cross-spectrum methods
FAQ
What is the standard calibration interval for the N9040B UXA?
Keysight recommends annual calibration using Keysight-certified service centers or accredited third-party labs meeting ISO/IEC 17025 requirements.
Can the N9040B perform time-gated spectrum analysis?
Yes — the instrument supports time-gated FFT with user-defined gate width and position, synchronized to external triggers or internal event markers.
Is remote programming supported via SCPI or IVI drivers?
Yes — full SCPI command set compliance (IEEE 488.2) and IVI-COM/IVI-C drivers are included, with Python, MATLAB, and LabVIEW examples provided in the Keysight Instrument Control Bundle.
Does the UXA support external LO synchronization for phase-coherent multi-analyzer systems?
Yes — 10 MHz and 100 MHz reference inputs/outputs are provided, along with PTPv2 (IEEE 1588) over Gigabit Ethernet for sub-microsecond inter-unit alignment.
How is measurement uncertainty quantified for amplitude and frequency readings?
Uncertainty budgets are documented in Keysight’s N9040B Technical Specifications and Calibration Report templates, aligned with GUM (JCGM 100:2008) methodology and traceable to NIST SRMs.
