Wideband signal analysis for radar/EW design and spectrum management

November 30, 2016 // By Graham Prophet
Combining 800 MHz real-time bandwidth with 2-hours of streaming storage at full bandwidth, Tektronix’ RSA7100A wideband signal analysis spans 16 kHz to 26.5 GHz, covering a broad range of analysis needs for critical wide-bandwidth applications.

Designers of radar and electronic warfare (EW) communications systems and components need to perform modulation and pulse analyses at wider bandwidth, Tek notes. The RSA7100A reduces the cost of wideband signal capture, record, and analysis while increasing the likelihood of capturing wideband signal transients. The instrument can trigger on and measure signals of 700 nsec duration in the frequency domain in real time while offering in-depth signal analysis with SignalVu-PC RF and vector analysis software. Together these capabilities provide a significant improvement over many other high-end signal analyzers on the market today.

 

Spectrum managers also need to record and analyze hours of wide bandwidth data. Equipment to meet these requirements can be very expensive, often requiring piecemeal solutions from multiple vendors or limited use, purpose-built equipment. Capturing wideband signals is data intensive, requiring specialized systems for capturing real-time data and plenty of patience to sift through terabytes of files looking for the signals of interest. The RSA7100A allows users to record up to 2 hours of streaming capture to internal RAID storage at the full 800 MHz bandwidth for such applications as environment recording and long event sequence analysis. Once the wideband signal data has been captured, the DataVu-PC software application finds and marks events of interest hiding within terabytes of stored data. DataVu-PC offers amplitude search and mark plus pulse measurements. Up to 2,000,000 pulses can be characterized for power, pulse-width, repetition interval and start-stop frequencies. Measurements can be exported in Pulse Descriptor Word format for use with other tools. Using DataVu-PC, smaller IQ files can be saved from within the longer captured file based on search and mark or manual selection.

 

The RSA7100A is priced starting at $135,000.
