Frequency Metrics (Advanced Radar)

Menu Path: Trace > Data > Result Tables

This topic describes the Frequency metrics displayed in the Pulse Table.

• Freq Mean (Hz)

  • Freq Mean in Hz, reports the mean frequency value measured over the user-specified sample analysis time interval as determined by Use Same Data as Frequency/Phase Analysis checkbox property.

  • When Use Same Data as Frequency/Phase Analysis checkbox is enabled, Freq Mean (Hz) measurement sample time window location and length is determined by the user-specified offset From Pulse Top Start and offset From Pulse Top End properties. The offset from pulse top start and offset from pulse top end must be specified separately for the following pulse modulations: CW, LFM, TFM, and Barker.

    

  • When Use Same Data as Frequency/Phase Analysis checkbox is disabled, Freq Mean (Hz) measurement sample time window location and length is determined by the user-specified Pulse-to-Pulse analysis offset From Pulse Top Start and offset From Pulse Top End properties.

    

  • Default visibility: ON

• Freq Pulse-Pulse Diff (Hz)

  • Freq Pulse-Pulse Diff in Hz, reports the mean frequency pulse-to-pulse difference value relative to the first valid detected pulse (Pulse 1) measured over the user-specified sample analysis time interval as determined by Use Same Data as Frequency/Phase Analysis checkbox property. The value shown for the 1st pulse is 0 Hz.

  • When Use Same Data as Frequency/Phase Analysis checkbox is enabled, Freq Pulse-Pulse Diff in Hz measurement sample time window location and length is determined by the user-specified offset From Pulse Top Start and offset From Pulse Top End properties. The offset from pulse top start and offset from pulse top end must be specified separately for the following pulse modulations: CW, LFM, TFM, and Barker.

    

  • When Use Same Data as Frequency/Phase Analysis checkbox is disabled, Freq Pulse-Pulse Diff in Hz measurement sample time window location and length is determined by the user-specified Pulse-to-Pulse analysis offset From Pulse Top Start and offset From Pulse Top End properties.

    

  • Default visibility: OFF

• Freq Pk-Pk Dev (Hz)

  • Freq Peak-to-Peak Dev in Hz, reports the peak to peak frequency deviation measured over the user-specified sample analysis time interval as determined by the offset From Pulse Top Start and offset From Pulse Top End properties.

  • Default visibility: OFF

• Freq Error RMS (Hz)

  • Freq Error RMS in Hz, reports the root-mean-square frequency error difference between FM Frequency Modulation Meas Time trace and FM Ref Time trace measured over the user-specified sample analysis time interval as determined by the offset From Pulse Top Start and offset From Pulse Top End properties.

  • Default visibility: ON

• Freq Error Peak (Hz)

  • Freq Error Peak in Hz, reports the absolute maximum frequency error difference between FM Meas Time trace and FM Ref Time trace measured over the user-specified sample analysis time interval as determined by the offset From Pulse Top Start and offset From Pulse Top End properties.

  • Default visibility: OFF

• Freq Error Peak Loc (sec)

  • Freq Error Peak Loc in seconds, reports the time location offset from start user specified sample analysis time interval (as determined by the offset From Pulse Top Start and offset From Pulse Top End properties) to the Freq Error Peak (Hz) occurrence.

  • Default visibility: OFF
