Keysight N9912CU/350 Real-Time Spectrum Analyzer Option

Overview

Option 350 is the Real-Time Spectrum Analyzer (RTSA) option for FieldFox C-Series analyzers (requires Option 233 Spectrum Analyzer; preamplifier Option 235 recommended). This option combines fast, overlapping FFT processing with gap-free data acquisition to detect signals independent of amplitude accuracy. RTSA capabilities are essential for identifying elusive interference sources in modern wireless environments where digital modulation and burst-transmission methods make reliable detection difficult.

Key Features

• Spectrum density view showing frequency and amplitude points for spectral occupancy insight
• Gap-free data acquisition for comprehensive signal monitoring
• Fast, overlapping FFT processing technique for real-time analysis
• Recording and playback functionality for offline data analysis
• Switch between real-time and conventional spectrum analyzer modes with one keystroke

Applications

• Wireless network interference source identification and localization
• Spectrum occupancy monitoring in congested frequency bands
• Military and commercial communication network troubleshooting
• Detection of signals with low power levels in complex RF environments

Technical Requirements

RTSA requires Option 233 (Spectrum Analyzer). The preamplifier option is recommended, as elusive signals often have low power levels. For N9912C models, the SA option and B04 for 40 MHz bandwidth are required.
