Highlights

Enable deeper insights in measurement and analysis by expanding the capabilities of your FieldFox handheld analyzer with field-upgradeable software licenses. These capabilities are engineered to deliver benchtop results into the field.

  • Handle routine maintenance and in-depth troubleshooting with one instrument
  • Maximize performance with a spectrum analyzer, built-in power meter, vector voltmeter, and more
  • Order with a new instrument or upgrade an existing instrument
Base model includes a spectrum analyzer (SA).

Spectrum Analysis

  • 209 – Extended Range Transmission Analysis (ERTA)

    Measure the scalar transmission gain or loss of waveguide systems, mixers, converters, and long cables where the two ends cannot easily meet.

  • 220 – Full-band Tracking Generator

    Elevate your Spectrum Analyzer with the dynamic tracking generator for precise frequency tracking in SA mode.

  • 235 – Pre-amplifier

    Increase spectrum analyzer sensitivity and reduce the DANL.

  • 236 – Interference Analyzer and Spectrogram

    Identify interfering signals quickly and accurately using the spectrogram or waterfall display. Record traces over time and store for offline processing.

  • 238 – Spectrum Analyzer Time Gating

    Measure the spectrum of a periodic signal during a specified time interval.

  • 350 – Real-Time Spectrum Analyzer (RTSA)

    Use gap-free, real-time spectrum analysis (RTSA) with 100 MHz of real-time bandwidth to capture small and intermittent signals masked by larger signals.

  • 351 – I/Q analyzer (IQA)

    Demodulate I/Q data and verify final signal chain integration or troubleshoot signal quality degradation due to hardware or software issues.

  • 353 – IQ Streaming

    Provide gapless IQ data to external application software to perform spectrum monitoring, demodulation, and decoding.

  • 355 – Analog Demodulation

    Demodulate and characterize AM and FM signals of radio transmitters.

  • 356 – Noise Figure (NF)

    Characterize devices like low noise amplifiers, frequency converters, and receivers with portable, one-button Y-factor noise figure and gain measurements.

  • 361 – Electromagnetic Interference (EMI) Measurements

    Evaluate EMI pre-compliance limits, perform equipment or network regulatory audits, and troubleshoot circuit boards.

5G / LTE Field Test

  • 312 – Channel Scanner

    Verify signal coverage, detect interference, and optimize network performance using simultaneous channel power measurements for up to 20 channels.

  • 358 – Electromagnetic Field (EMF) Measurements

    Evaluate total RF exposure levels. Verify compliance with regulatory and government requirements using a triaxial isotropic antenna.

  • 370 – Over-the-Air (OTA) LTE FDD

    Analyze LTE FDD cell information transmitted over-the-air and optimize inter-RAT handovers for overlapping 5G and LTE networks.

  • 371 – Over-the-air (OTA) LTE TDD

    Uncover the 4G cells available at a specific frequency or component carrier for LTE signals using the time division duplex frame structure.

  • 378 – Over-the-air (OTA) 5G NR

    Measure and decode 5G NR signal quality metrics to verify the 5G coverage at FR1 or FR2 frequencies.

  • B04 – Analysis Bandwidth, 40 MHz

    Optimize signal analysis for communication signals like scalable multi-channel LTE with 40 MHz bandwidth.

  • B10 – Analysis Bandwidth, 120 MHz

    Enable quantifications for bandwidth-hungry modern signals such as in 5G NR and satellite communications with 120 MHz bandwidth.

Power Measurements

  • 208 – USB Power Measurements versus Frequency

    Characterize the scalar transmission response of devices such as mixers and converters using USB power sensor measurements versus frequency.

  • 302 – USB Power Sensor Support

    Characterize RF pulses such as those used in radar and electronic warfare systems using a USB peak power sensor.
