  • Page 463: Appendix E Iq Data Time Actually Required

    Appendix E IQ Data Time Actually Required IQ data time actually required In FFT and filtering processing, additional IQ data time is required for calculation in addition to the specified capture time. The Signal Analyzer function automatically calculates the data length required for calculation to capture the data.
  • Page 464 Appendix E IQ Data Time Actually Required The minimum capture time for the Frequency vs Time trace is as shown below. IQ data time Analysis time Detection length Detection length Smoothing length Smoothing length Filter tap length Filter tap length Figure E-3 IQ data time for the Frequency vs Time trace The Frequency vs Time trace performs band limiting processing, so the data required for the calculation is captured, which is longer than the...

IQ data time Analysis time Detection length Detectionlength Window function length Window function length Figure E-5 IQ data time for the Spectrogram trace The Spectrogram trace uses the FFT method for calculation, so data with window function length is captured as required data length for calculation in addition to the specified analysis time.
  • Page 466 Appendix E IQ Data Time Actually Required Auto mode and Manual mode for capture time When Capture Time is set to the Auto mode, the data length required for calculation is automatically set to the minimum data length. This makes the IQ data time actually captured the shortest, allowing the user to obtain analysis results in the shortest time.
