Reference Region Count

Menu Path: MeasSetup > FMCW Radar Properties > Reference Synchronization

Reference Region Count describes the number of unique LFM regions contained within each repetition instance of the measured signal's LFM region-group pattern. This value is used for Reference Region identification within FMCW Region Table results, plus associated Reference Region statistical metric reporting within Current Record Statistics and Cumulative Statistics tables.

• Automatic
  • By default, the FMCW analysis software automatically determines an appropriate Reference Region Count value based on the measured FM Frequency Modulation Slope (Hz/us) modulation trace results observed over the Acquisition Length time. This automatically determined Reference Region Count value is reported in FMCW Summary results table as the Ref Region metric.
• Manual
  • Alternatively, you can manually specify an appropriate Reference Region Count value to use based on the measured signal's LFM region-group pattern.
• Default selection: Automatic
• Default value (Manual): 1
