Explore Software Options for the N9935B
Real-Time Spectrum Analyzer
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.
Extended Range Transmission Analysis
Measure the scalar transmission gain or loss of waveguide systems, mixers, converters, and long cables where the two ends cannot easily meet.
Y-Factor Noise Figure & Gain Measurements
Characterize devices like low noise amplifiers, frequency converters, and receivers with portable, one-button Y-factor noise figure and gain measurements.
In-Phase & Quadrature (I/Q) Analyzer
Demodulate I/Q data and verify final signal chain integration or troublesoot signal quality degradation due to hardware or software issues.
Interference Analyzer and Spectogram
Identify interfering signals quickly and accurately using spectogram or waterfall display. Record traces over time and store them for offline processing.
AM/FM Analog Demodulation
Demodulate and chracterize AM and FM signals of radio transmitters by visualizing the RF spectrum, waveform, and metrics such as carrier power and modulation rate.
Phased Array Antenna Control
Deploy and optimize 5G technologies like massive MIMO by verifying base station beam characteristics and signal power across azimuth and elevation.
Over-the-Air 5G NR Measurements
Analyze 5G NR FR1 and FR2 cell information transmitted over-the-air and optimize inter-RAT handovers for overlapping 5G and LTE networks.
Over-the-Air 5G TF Measurements
Demodulate and analyze 5GTF cell information transmitted over-the-air from base station downlink multi-path and multi-cell environments.
Over-the-Air LTE FDD Measurements
Analyze LTE FDD cell information transmitted over-the-air and optimize inter-RAT handovers for overlapping 5G and LTE networks.
Frequency Channel Scanner
Verify signal coverage, identify potential interference issues, and optimize network performance with channel power measurements of up to 20 channels at once.
Electromagnetic Field (EMF) Measurements
Evaluate total RF exposure levels in any given area. Verify compliance to regulatory and government requirements using a triaxial isotropic antenna.
USB Power Measurements vs. Frequency
Characterize the scalar transmission response of devices such as mixers and converters using USB power sensor measurements versus frequency.
Built-in Power Meter
Make accurate, user-definable channel power measurements such as transmitter output power with no additional external hardware.
USB Power Sensor Pulse Measurements
Characterize RF pulses such as those used in radar and electronic warfare systems using a USB peak power sensor.
Remote Control Capability
View and control FIeldFox remotely using an iOS device.
Built-in GNSS/GPS Receiver
Attach geolocation tags to measurements with a built-in GNSS/GPS receiver.
DC Bias Variable Voltage Source
Provide power to amplifiers under test and bias tower mounted amplifiers.
Indoor & Outdoor Mapping
Import indoor and outdoor maps for data collection and plotting to the map.
Full-Band Built-in Preamplifier
Increase spectrum analyzer sensitivity and reduce the DANL.
Full-Band Tracking Generator
Measure scalar stimuli/responses of active and passive components.
