A live sample is one whose value is greater than the value of the SMALLEST_ABS_AMP parameter, Amplitude Reject Limits parameter set and that falls below the trace header literal START_TIME plus parameter START_TIME_DELAY. The trace balance factor (TRACE_BALANCE_FACTOR trace header literal) is less than the MIN_TRC_BAL_FACTOR parameter, Amplitude Reject Limits parameter set. The trace balance factor is greater than the MAX_TRC_BAL_FACTOR parameter, Amplitude Reject Limits parameter set.
