User Options for Hardware: Time Stamp Plausibility Check Dialog Box
To open this dialog box, click the User
Options
button and select the Hardware
tab. On the Hardware tab, double-click in
the Value field of the Time Stamp
Plausibility Check option.
If the plausibility checking of time stamps has been activated, plausibility violations can be displayed in the Recorder Manager. If they have been logged in the measurement file (*.mdf), they can be displayed in the MDA in the comment fields of the measurement.
To check the plausibility of time stamps, you can make the following settings:
Time stamp monotony check
Defines the behavior when the characteristic of the time stamp does not rise in a strictly monotonous fashion.
Off
Time stamps are not checked for monotony (default setting).
Report but continue measurement
The measurement is continued even if time stamps which violate monotony occur. Time stamps are not corrected, but all errors are logged in an error report.
Report and stop measurement
The measurement is discontinued if time stamps which violate monotony occur.
Report and correct error
Time stamps which violate monotony are corrected, and the measurement is continued.
Sample frequency plausibility check
Defines the behavior when the sample frequency deviates from the expected frequency. The tolerance threshold for the sample frequency can be set under Sample frequency plausibility check.
Off
The sample frequency is not checked for plausibility (default setting).
Report but continue measurement
The measurement is continued even if sample frequencies are outside the set tolerance. Time stamps are not corrected , but all errors are logged in an error report.
Report and stop measurement
The measurement is discontinued if sample frequencies are outside the set tolerance.
Report and correct error
Time stamps where the sample frequency is outside the set tolerance are corrected and the measurement is continued.
Sample frequency plausibility tolerance [%]
Defines the tolerance for the sample frequency as a percentage. Large deviations are regarded as plausibility violations.
Values from 0 % to 500 % can be specified; the default value is 25 %.
Logging of plausibility violations
Defines whether plausibility violations with regard to time stamp monotony and sample frequency are to be logged in the measurement file (*.mdf).
Off
Plausibility violations are not logged in the measurement file.
To measurement file (MDF)
All plausibility violations are written to the measurement file together with the actual measurement.
