This topic describes the Frequency metrics displayed in the Result Tables, Histograms, and Trend Lines.

• 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 user specified Frequency/Phase Analysis Width (%) property.

  • 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 property time settings for Reference Time, Offset (s) and Window Length (s).

  • 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 user specified Frequency/Phase Analysis Width (%) property.

  • 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 property time settings for Reference Time, Offset (s) and Window Length (s).

  • Default visibility: OFF

• Freq Pk-Pk Dev (Hz)

  • Freq Peak-to-Peak Dev in Hz, reports the peak to peak frequency deviation measured over user specified sample analysis time interval as determined by Frequency/Phase Analysis Width (%) property.

  • 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 user specified sample analysis time interval as determined by Frequency/Phase Analysis Width (%) property.

  • 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 user specified sample analysis time interval as determined by Frequency/Phase Analysis Width (%) property.

  • 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 Frequency/Phase Analysis Width (%) property) to the Freq Error Peak (Hz) occurrence.

  • Default visibility: OFF
