    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 422 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.
