This attribute specifies the lower boundary for a bin. The upper boundary is defined by the next bin value or infinite for the last bin defined. The boundary for each bin must be larger than the boundary of the preceding bin. By default, the next bin is set to 5000us larger than the lower bin boundary. The values in a bin boundary object represents the time range used to segregate delay data into the appropriate statistical data bin. For five bins with default values, each bin has the following time range: bin 1 = 0, represents a range is 0u <= measurement < 5,000us bin 2 = 5000, represents a range is 5,000us <= measurement < 10,000us bin 3 = 10000, represents a range is 10,000us <= measurement < 15,000us bin 4 = 15000, represents a range is 15,000us <= measurement < 20,000us bin 5 = 20000, represents a range is 20,000us <= measurement < infinity The values in a bin boundary object represents the time range used to segregate delay data into the appropriate statistical data bin. The first bin boundary always contains the value of 0. Attempting to write a non-zero value to this bin will result in an error. Note that the upper limit of the range for the last measurement bin is effectively 5 seconds (or 5,000,000 us).
