The Communications Signal Analyzer (CSA) is an optional SE application which complements the SA's capabilities by providing real-time automatic analysis of intercepted signals. Powerful digital signal processing is used for modulation and communication system recognition. A number of graphical displays provide different views of the analyzed data.

• Real-time modulation type identification:
  • CW, AM, DSB-SC, SSB, FM, FSK, MSK-type, BPSK, QPSK, p/4-QPSK, 8PSK, M-QAM, M-16-QAM, OTHER, NOISE
• Communication systems identification:
  • AMPS, US Digital Cellular, GSM, iDEN, Sub-audio FM, Broadcast FM stereo
• Technical Parameter Estimation:
  • Signal-to-Noise Ratio, Signal Bandwidth, Carrier Frequency, Symbol Rate
• Multiple Displays, including:
  • Frequency, phase and amplitude content
  • Modulation and instantaneous frequency histogram
• Compliant with the ITU-R SM series of recommendation
• Complementary interworking with the Spectrum Analyzer application
