Description
Overview
The Keysight N9918B-350 brings real-time spectrum analysis (RTSA) capability to FieldFox portable instruments. With 100 MHz real-time bandwidth and gap-free processing, it enables detection of fleeting signals that might be masked by larger interferers or missed by conventional swept-spectrum analyzers. Recording and playback functionality allows field capture for offline analysis.
Key Features
- Gap-free real-time spectrum analysis with 100 MHz real-time bandwidth
- Captures signals as narrow as 5.52 µs with 100% probability of intercept and full amplitude accuracy
- Detects signals as short as 47 ns when amplitude accuracy is not critical
- 59 dB spur-free dynamic range
- Spectrum density view for visualizing spectral content
- Spectrogram and real-time spectrum displays
- Record and playback of spectrum traces for offline analysis
Applications
- Intermittent signal detection and interference analysis
- Burst transmission and digital modulation monitoring
- Low-level signal detection in high-interference environments
- Field troubleshooting and spectrum characterization
- Post-capture offline analysis of complex RF environments
