Introducing the N9912C FieldFox Handheld RF Analyzer

Keysight Technologies is broadening its FieldFox lineup by introducing the N9912C FieldFox Handheld Analyzer. This software-defined radio frequency (RF) testing platform grants field engineers access to over 20 options, including vector network analyzer (VNA), cable and antenna tester (CAT), and spectrum analyzer (SA) capabilities for upgrade and download.


The new FieldFox C-model, covering up to 10 GHz, offers the following benefits:

  • Mix and match options – Provides incomparable versatility in constructing the ideal combination of VNA, CAT, and SA tools to meet the specific demands of each project. It encompasses over 20 downloadable software applications and activates frequency and bandwidth options through license keys. Furthermore, the maximum frequency ranges for all types of analyzers can be expanded by acquiring an upgrade option for existing N9912C devices.
  • Pay only for what you need – Enhances the efficiency of field instrument allocation by empowering engineers to select the specific functionalities required for their field tasks.
  • Save time in the field with a single handheld – Remove the necessity to interchange devices by utilising a solitary, durable portable analyzer that can be modified on the go to accommodate changing testing requirements.
  • High-performance analysis – Offers precise and extensive examination of spectrum and network, covering 3 kHz to 10 GHz, for the purpose of testing and resolving issues in various high-frequency and wireless applications.

Enhance your understanding and examination through the expansion of your FieldFox handheld analyzer's potential using software licenses that can be upgraded in the field. These functionalities are designed to bring laboratory-level outcomes to field operations.

  • Efficiently manage regular upkeep and extensive problem-solving tasks with a single device.
  • Optimise performance with a network analyzer, spectrum analyzer, integrated power meter, vector voltmeter, and additional features.
  • Acquire alongside a new device or enhance an existing one.

Tailor your base model by adding an optional cable and antenna tester (CAT), vector network analyzer (VNA), or signal analyzer (SA), in any desired combination.
