Explore Software Options For the N9937A
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 and 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 characterize AM and FM signals of radio transmitters by visualizing the RF spectrum, waveform, and metrics such as carrier power and modulation rate.
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.
Evaluate total RF exposure levels in any given area. Verify compliance to regulatory and government requirements using a triaxial isotropic antenna.
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.
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.
