Keysight's FieldFox handheld RF and microwave analyzer

Keysight adds new features to its FieldFox handheld RF and microwave analyzers

  • Keysight Technologies integrates signal demodulation, vector signal analysis, I / Q data analysis to its FieldFox portable signal analyzers.
  • Handheld RF and microwave analyzersFieldFox analysers’s range offers a frequency band of 4 to 50 GHz, depending on the model.
  • Equipped with the new 89600 VSA software link, this handheld I / Q analyzer can be used for field installation and maintenance, interference identification and analysis, and signal demodulation.

Keysight Technologies FieldFox RF and Microwave Analyzers now connect to the Keysight 89600 VSA software, providing a set of tools for signal demodulation and vector signal analysis.

The FieldFox to 89600 VSA link provides hardware and software capabilities for the design and troubleshooting of devices using signal formats used in the public radio safety (Apco-25 and Tetra standards), wireless vehicular communications (IEEE 802.11p), low-power wide area networks and Internet objects (IoT), as well as cellular telecommunications (LTE, WCDMA and GSM).

Option 351 transforms the Fieldfox analyzer into a portable I / Q capture and analysis solution for field communication system testing applications, identification and analysis of radio frequency interference and signal demodulation .

The FieldFox analyzer delivers frequency and time measurements and offers customizable multi-domain display. The I / Q data are captured and analyzed directly on the instrument. It is also possible to capture data for postprocessing with 89600 VSA software from Keysight, Matlab, Python Toolkit or other third party demodulation software.

FieldFox’s I / Q analyzer mode also provides for baseband subsystem verification and final integration of the signal chain as well as identification of the origin of signal quality degradation based on hardware and software problems.

Understanding RF signal environments is facilitated by the regeneration and reading of captured I / Q data using a vector signal generator. In addition, environmental fading profiles can be applied to the I / Q data using a vector signal generator to determine the performance of a receiver.

The FieldFox analyzer captures up to 10 MHz of flatness- and phase-corrected I/Q data, and measure magnitude spectrum (frequency domain) and RF envelope as well as I/Q waveform (time domain). Up to four simultaneous and multi-domain measurement views can be customized.

Functions such as amplitude and frequency alignment prior to signal capture can improve performance. FieldFox saves captured I / Q data in different comma separated value file types: CSV, Text (TXT), SDF (compatible with 89600 VSA), and Matlab (MAT).
