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

• Phase Mean (deg)

  • Phase Mean in deg, reports the mean phase 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, Phase Mean (deg) 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, Phase Mean (deg) 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

• Phase Pulse-Pulse Diff (deg)

  • Phase Pulse-Pulse Diff in deg, reports the mean phase 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 degrees.

  • When Use Same Data as Frequency/Phase Analysis checkbox is enabled, Phase Pulse-Pulse Diff in deg 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, Phase Pulse-Pulse Diff in deg 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

• Phase Pk-Pk Dev (deg)

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

  • Default visibility: OFF

• Phase Error RMS (deg)

  • Phase Error RMS in deg, reports the root-mean-square phase error difference between Phase Meas Time trace and Phase Ref Time trace measured over user specified sample analysis time interval as determined by Frequency/Phase Analysis Width (%) property.

  • Default visibility: ON

• Phase Error Peak (deg)

  • Phase Error Peak in deg, reports the absolute maximum phase error difference between Phase Meas Time trace and Phase Ref Time trace measured over user specified sample analysis time interval as determined by Frequency/Phase Analysis Width (%) property.

  • Default visibility: ON

• Phase Error Peak Loc (sec)

  • Phase 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 Phase Error Peak (deg) occurrence.

  • Default visibility: OFF
