Overview
The Keysight N9020B MXA Signal Analyzer is a high-performance, application-optimized RF and microwave signal analysis platform engineered for the rigorous demands of modern wireless device development and validation. Based on proven heterodyne superheterodyne architecture with advanced digital IF processing, the N9020B delivers exceptional amplitude accuracy, phase linearity, and dynamic range across its full 10 Hz to 50 GHz frequency span. Its core measurement engine supports both swept-tuned and FFT-based analysis modes, enabling precise spectral, modulation, and time-domain characterization of complex waveforms—including 5G NR, Wi-Fi 6E/7, UWB, and satellite communication signals. The instrument’s wide 160 MHz instantaneous analysis bandwidth facilitates high-fidelity capture of wideband modulated signals, while its real-time spectrum analysis capability—covering the entire frequency range without gaps—ensures reliable detection and analysis of transient, intermittent, or frequency-hopping emissions.
Key Features
- Full-frequency-range real-time spectrum analysis with 100% probability of intercept (POI) for events as short as 3.57 µs
- Multi-touch capacitive display with gesture-driven navigation, reducing operator training time and minimizing measurement setup errors
- Hardware-accelerated power measurements—including channel power, ACLR, OBW, and CCDF—executed in real time without host CPU dependency
- Fast sweep engine supporting >100 sweeps per second at 1 kHz RBW, significantly accelerating production test throughput
- Extended I/Q recording capability (up to 160 MHz bandwidth × >30 s duration) for deep signal reconstruction and post-processing
- Built-in EVM measurement engine compliant with 3GPP TS 38.141 and IEEE 802.11ax standards, delivering ≤0.3% RMS EVM at –50 dB reference level
Sample Compatibility & Compliance
The N9020B supports direct RF input up to +30 dBm (with internal preamplifier disabled) and features configurable input attenuation, 50 Ω impedance matching, and optional high-pass/low-pass filtering for optimal signal conditioning. It is compatible with external mixers (e.g., Keysight N9020B-526) for extension beyond 50 GHz, and integrates seamlessly with calibrated active probes and antenna test systems. From a regulatory perspective, the analyzer conforms to CE, FCC Part 15 Subpart B, and RoHS directives. Its firmware and measurement algorithms are validated per ISO/IEC 17025 requirements for accredited calibration laboratories. When used with PathWave X-Series software under controlled IT environments, the system supports audit trails, electronic signatures, and data integrity controls aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations for regulated R&D and manufacturing workflows.
Software & Data Management
The N9020B ships with embedded PathWave X-Series measurement applications—including modulation analysis (MQA), noise figure (NFA), phase noise (PNA), and pulse analysis (PUA)—all accessible via intuitive one-button measurement workflows. All applications support scripting via SCPI and Python (via Keysight IO Libraries Suite), enabling automated test sequences and integration into CI/CD pipelines. Measurement results—including raw I/Q data, trace buffers, and metadata—are stored in industry-standard formats (e.g., .csv, .mat, .wfm) with timestamping, instrument configuration snapshots, and user-defined annotation fields. Data export is fully scriptable and supports secure transfer protocols (SFTP, HTTPS) for integration with LIMS or PLM systems. Firmware updates are delivered through Keysight’s official support portal and include version-controlled release notes and regression test reports.
Applications
- 5G NR FR1/FR2 transmitter conformance testing per 3GPP Release 16/17
- Wi-Fi 6E/7 OFDMA and MU-MIMO signal integrity verification
- Radar waveform analysis (FMCW, pulsed Doppler) in automotive and defense R&D
- EMI pre-compliance screening in accordance with CISPR 16-1-1 and MIL-STD-461G
- IoT device spectral mask validation and spurious emission monitoring
- Phase noise characterization of local oscillators and synthesizers in satellite transceivers
FAQ
Does the N9020B support external mixing for frequencies above 50 GHz?
Yes—when equipped with option 526 and paired with Keysight’s V-band or W-band harmonic mixers, the N9020B can perform calibrated measurements up to 110 GHz.
Is real-time spectrum analysis available across the entire 10 Hz–50 GHz range?
Yes—the instrument performs gap-free real-time analysis across its full frequency span using overlapping FFT processing and deep memory buffering.
Can measurement data be exported in formats compatible with MATLAB or Python?
Yes—all I/Q data, traces, and results are exportable as IEEE 488.2-compliant .csv or HDF5 files, with full metadata embedding for reproducible analysis.
What calibration options are available for production environments?
Keysight offers factory calibration (ISO/IEC 17025 accredited), on-site calibration services, and self-calibration routines with documented uncertainty budgets traceable to NIST standards.
How does the N9020B ensure measurement repeatability in high-throughput test systems?
Through deterministic trigger latency (<100 ns jitter), hardware-synchronized I/O ports (GPIB, LAN, USB), and deterministic firmware execution paths verified via Keysight’s internal metrology lab.
