Description

N9938B | FieldFox 9 kHz - 26.5 GHz Signal Analyzer

The Keysight FieldFox B series combines cable & antenna tester (CAT), vector network analyzer (VNA) and spectrum analyzer (SA) in one robust, battery-operated handheld device. The analyzers are designed for field use: shockproof, dustproof and splashproof, with a large display that is easy to read in sunlight, large buttons (can also be operated with gloves) and a field-swappable battery for several hours of measurement operation. Thanks to CalReady, the device is ready to measure as soon as it is switched on; optional ECal modules speed up precise calibrations. Software options such as Real-Time Spectrum Analysis (RTSA) up to 120 MHz, IQ Analyzer/Streaming, Noise Figure, Pulse Measurements, EMF/EMI and OTA Measurements (LTE/5G NR) are available for demanding applications. Typical applications include installation, troubleshooting and maintenance of mobile radio, SAT, radar, broadcast, WLAN and industrial RF systems - from cable termination to filters/amplifiers and over-the-air analysis.

The N9938B is the top model of the N993xB series within the FieldFox-B family and offers an operating frequency range from 9 kHz to 26.5 GHz. It is the most powerful portable spectrum analyzer in this model series and covers the entire microwave spectrum up to the upper Ku band. This makes it ideal for satcom, radar, 5G, defense and RF development applications where precision and high bandwidth are critical. Compared to the N9937B (up to 18 GHz), the N9938B offers the extended frequency range up to 26.5 GHz, enabling detailed analysis of signals, components and systems in the upper microwave range. The operating concept, range of functions and software options are identical within the series, so that the N9938B offers maximum performance and flexibility with the same field suitability.

Technical product features of the series:

  • Meter combination: CAT, VNA and/or SA depending on the model; the N9938B is a specialized spectrum analyzer with optional functions for RTSA and IQ analysis.
  • Frequency ranges depending on model: from 30 kHz to 26.5 GHz (N9933B to N9938B); the N9938B covers the maximum range of the series.
  • Ruggedized design: for field use (-10 ... +55 °C), shock/vibration-resistant; dust and splash-proof design according to MIL standard.
  • Mobile & ergonomic: approx. 3.3 kg, large transflective display, large buttons, glove-operated, replaceable battery (up to 4.5 h runtime).
  • High measurement accuracy: Stable frequency oscillator (±0.9 ppm), optional GPS reference, automatic calibration; excellent amplitude accuracy over the entire frequency range.
  • Flexible analysis: Options for RTSA (up to 120 MHz real-time BW), IQ acquisition/streaming, noise figure, pulse and EMC measurements, OTA (LTE/5G), channel scanner, interference/spectral monitoring.
  • Dynamics & sensitivity: Typically up to 112 dB dynamic range, with preamplifier up to 100 dB below 2 MHz and 112 dB up to 7 GHz; high linearity and low self-noise level.
  • Interfaces & GPS: USB & LAN, external Ref/Trigger, optional integrated GNSS, support for external USB power sensors and built-in power meter (option).
  • Software ecosystem: Connection to PathWave 89600 VSA, Keysight Surveyor/Spectrum Management and others. etc.; remote control via SCPI.
  • Accessories & upgrades: numerous field upgrades via license key (RTSA, pulse analysis, EVM, noise figure, OTA, EMI analyzer, tracking generator and much more).
