Keysight N9916B-350 Spectrum Analyzer

Overview

The Keysight N9916B-350 is a real-time spectrum analyzer (RTSA) that enables users to detect and analyze interference in complex wireless environments. Its gap-free measurement capability and 100 MHz real-time bandwidth allow capture of small and intermittent signals that might otherwise be masked by larger signals using advanced overlapping FFT processing techniques.

The device is particularly valuable for identifying and mitigating interference sources, especially in environments with digital modulation and burst-transmission methods. It can capture signals as narrow as 5.52 µs with full amplitude accuracy and 100% probability of intercept (POI), or detect pulses as narrow as 47 ns when amplitude accuracy is not the primary concern.

Key Features

• Gap-free real-time spectrum analysis with 100 MHz real-time bandwidth
• Captures signals as short as 5.52 µs with 100% POI and full amplitude accuracy
• Detects signals as short as 47 ns for detection-critical applications
• 59 dB of spur-free dynamic range
• Three display modes: density spectrum, spectrogram, and real-time spectrum
• Record and playback functionality for offline analysis of captured traces

Applications

• Wireless interference detection and source localization
• Network quality monitoring and communication link diagnostics
• Signal detection in presence of high-power transmitters
• Time-domain data collection for post-analysis investigations
