Differential Delay
Slowest Member: Indicates the member having the largest differential
delay. The member having the largest SQ will be selected when more
than one member has the largest differential delay.
Fastest Member: Indicates the member having the smallest differential
delay. The member having the smallest SQ will be selected when more
than one member has the smallest differential delay.
Relative Delay: Indicates the differential delay that exists between the
slowest and fastest members.
Alarm Analysis
LOA (Loss Of Alignment): The LOA alarm is declared when the
alignment process cannot perform the alignment of the individual
member within the defined threshold.
LOA Threshold (Loss Of Alignment Threshold): Allows to specify the
value at which an LOA alarm will be declared.
Choices are from 125 to 255375 μs for HOP and to 254000 μs for LOP
except for TU-3. The default setting is 100000 μs.
Reference Member
Allows the selection of the reference member from the list or automatically
when Auto is enabled.
Auto: Performs automatic selection of the fastest member having the
smallest differential delay. The member having the smallest SQ will be
selected when more than one member has the smaller differential delay.
The default setting is Auto enabled.
Measurement Unit
Allows the selection of unit for both the differential delay and LOA
Threshold. Choices are ms and μs. The default setting is μs.
