Real-time spectrum analyzer (RTSA)

• Spectrum density view shows frequency and amplitude points for insight into a frequency band's spectral occupancy.
• Find a signal quickly using recording and playback to analyze saved data offline.
• With RTSA shift to real-time capabilities with one key press.
• RTSA requires option 233 (Spectrum Analyzer), recommends 235 (Preamplifier). N9912C Require SA option, B04 for 40MHz

With the widespread increase of wireless technologies in commercial and military networks, various types of interference fill the spectral environment. The interfering signals result in network quality deterioration and communication link breakdowns. Additionally, use of digital modulation and burst-transmission methods have made it difficult to reliably detect interference sources. Real-time spectrum analyzer (RTSA) in FieldFox helps by combining a fast, overlapping FFT processing technique and gap-free data acquisition. Detecting signals, independent of amplitude accuracy, can be a critical factor.

RTSA or Option 350 on a FieldFox must be equipped with spectrum analysis capability. The preamplifier option is also recommended, as elusive signals often have low power levels.
