Keysight N9040B UXA Signal Analyzer:Covers 2 Hz to 50 GHz, extendable to 110 GHz with Keysight smart mixers, and even to terahertz bands with third-party solutions.
The N9040B is a flagship-grade tool in the R&D lab for "dissecting" the most extremely complex signals. If your customer is involved in radar, electronic warfare, satellite communications, 5G/6G frontier R&D, or requires extremely in-depth transient and modulation analysis of Bluetooth/WLAN/RFID signals, this instrument is a matching choice; if it is only for routine production-line calibration or simple CW testing, its performance would be severely redundant.

Keysight N9040B UXA Signal Analyzer: Core Parameters, Applicable Industries and Scenarios at a Glance
Core Conclusion: The N9040B is Keysight's flagship UXA signal analyzer in the X-Series, positioned above the N9030B PXA. Its core advantages lie in up to 1 GHz analysis bandwidth, 510 MHz real-time bandwidth, and industry-leading phase noise performance. It is designed for scenarios requiring the "dissection" of extremely complex signals, such as radar, electronic warfare, satellite communications, and 5G/6G R&D.
Core Parameters at a Glance
Frequency Range
Covers 2 Hz to 50 GHz, extendable to 110 GHz with Keysight smart mixers, and even to terahertz bands with third-party solutions.Analysis Bandwidth
Maximum analysis bandwidth of 1 GHz, with bandwidth options including 25 MHz (standard), 40 MHz, 255 MHz, 510 MHz, and 1 GHz.Real-Time Bandwidth
Maximum real-time bandwidth of 510 MHz, supporting gapless capture with 100% probability of intercept for signals as short as 3.517 μs.Phase Noise

Over 78 dBc within 510 MHz bandwidth, enabling detection of small signals in the presence of strong signals.Displayed Average Noise Level (DANL)
As low as -166 dBm to -174 dBm at 1 GHz (depending on configuration and whether the low-noise path/NFE is enabled).Amplitude Accuracy
Overall amplitude accuracy of ±0.16 dB, a leading level in its class.Other Key Capabilities
Features a 14.1-inch multi-touch screen; standard Microwave Preselector Bypass (MPB) and Low Noise Path (LNP); supports real-time IQ streaming (up to 255 MHz).Applicable Industries and Typical Scenarios
1. Aerospace & Defense (Radar / Electronic Warfare)
This is the most core high-end application for the N9040B. Keysight officially positions it as an ideal tool for the most difficult-to-capture signals in radar and electronic warfare.Radar Signal Analysis: The 1 GHz analysis bandwidth can fully capture wideband radar pulses; the extremely low phase noise is fundamental for radar Doppler analysis and near-carrier weak target detection. It can precisely measure wideband chirp linearity and extremely narrow pulse signals with pulse depth >80 dB and rise/fall times as short as 6.0 ns.
Electronic Warfare and Signal Intelligence: The 510 MHz real-time bandwidth combined with gapless capture enables the capture of fast frequency-hopping and transient threat signals in complex dynamic electromagnetic environments.
2. Commercial Wireless Communications (5G / Satellite Communications / 6G Research)
Keysight lists "commercial communications" as a core application area for the UXA.5G NR and Wideband Signal Demodulation: The 1 GHz analysis bandwidth enables single-capture of ultra-wideband modulated signals, which can then be analyzed for EVM and constellation diagrams using 89600 VSA software.
Satellite Communications: Suitable for satellite transponder characterization and wideband satellite signal analysis.
6G Research: The UXA's unique Full Bypass Path (FBP), combined with MPB and LNP, achieves industry-leading wideband signal-to-noise ratio and is positioned as a "pioneer for the future" in 6G research and complex electromagnetic environment modeling.
3. Wireless Connectivity (Bluetooth / WLAN / RFID)
The N9040B is also suitable for in-depth verification of short-range wireless technologies.Bluetooth Testing: With the N9081EM0E option, it can perform one-button RF transmitter conformance testing for Bluetooth BR/EDR, LE 4.0/4.2, and Bluetooth 5, including output power, modulation characteristics, carrier frequency tolerance, and adjacent channel power.
RFID Signal Analysis: Real-time spectrum analysis capability can capture transient burst signals from RFID backscattering, measuring carrier frequency, occupied bandwidth, modulation depth, and frequency-hopping dwell time.
4. EMI Pre-Compliance Testing
Some distributor materials mention that the N9040B can be used for pre-compliance, debugging, and certification support in the EMC testing process, covering automotive, aerospace, medical, and industrial fields. However, this is a distributor positioning rather than Keysight's official description of the UXA's core scenarios.
