Description: Returns the time corresponding to the specified MTBF.
Field Format: [TIMEATMTBF(Source Number)(MTBF;Cumulative;Conf_Level)]
Source Number is the associated data source number.
MTBF is the value of the MTBF at which the time is calculated.
Cumulative allows you to specify either the cumulative or instantaneous MTBF.
Conf_Level is the percentage (entered as a decimal value) for the confidence bounds. It is an optional value and, if specified, must be greater than 0 and less than 1.
Remarks:
The Source Number must be either 1,2,3 or 4.
Cumulative is shown in the function as a numerical value that indicates the MTBF calculation; for cumulative MTBF = 1; for instantaneous MTBF = 0.
Example:
[TIMEATMTBF(1)(234;0;0.9)]
Returns:
2744.245089
Note that this value will vary depending on the source data set.
