N9937DU FieldFox Handheld Software

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

Measure scalar stimuli/responses of active and passive components.

Perform high-performance spectrum analysis with four trace options, different detector types, radio standard selection, and flexible limit lines.

Increase spectrum analyzer sensitivity and reduce the DANL.

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

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

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.

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

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

Demodulate and characterize AM and FM signals of radio transmitters by visualizing the RF spectrum, waveform, and metrics such as carrier power and modulation rate.

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

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

Perform last mile detection of an unknown signal source using manual signal triangulation.

Determine the location of an unknown signal source using several networked FieldFox analyzers with synchronized GPS signals.

Verify signal coverage, identify potential interference issues, and optimize network performance with channel power measurements of up to 20 channels at once.

Evaluate total RF exposure levels in any given area. Verify compliance to regulatory and government requirements using a triaxial isotropic antenna.

Support for a portable phased array antenna that enables beamforming and MIMO analysis for qualifying the 5G air interface in the field.

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

Provide insights to available 4G cells at a given frequency or the component carrier for the LTE signals with Time Division Duplex frame structure.

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

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

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