2
The following query returns the “Instantaneous” number of illegal symbol
count, calculated from the counts obtained in the last deci- second. This value
is available even when accumulation is turned off.
[P]FETCh[:SENSe[1]]:ISCCount[:ALL][:FULL]:DELTa?
3
The following query returns the ratio of the number of Illegal Symbol count to
the number of symbols received in the current (or last completed) accumulation
period, specified by the gate period.
[P]FETCh[:SENSe[1]]:ISRatio[:ALL][:FULL][:TOTal]?
4
The following query returns the "instantaneous" illegal symbol ratio (Actual
ISR) calculated from the counts obtained in the last deci-second. This value is
available even when accumulation is turned off.
[P]FETCh[:SENSe[1]]:ISRatio[:ALL][:FULL]:DELTa?
How to Evaluate Filler Symbol Results
You can use the following commands/queries to evaluate Filler Symbol results:
1
The following query returns total number of Filler symbol count received in a
time interval.
[P]FETCh[:SENSe[1]]:FSCount[:ALL][:FULL][:TOTal]?
2
The following query returns the “Instantaneous” number of filler symbol count,
calculated from the counts obtained in the last deci- second. This value is
available even when accumulation is turned off.
[P]FETCh[:SENSe[1]]:FSCount[:ALL][:FULL]:DELTa?
3
The following query returns the ratio of the number of filler Symbol count to
the number of symbols received in the current (or last completed) accumulation
period, specified by the gate period.
[P]FETCh[:SENSe[1]]:FSRatio[:ALL][:FULL][:TOTal]?
4
The following query returns the "instantaneous" filler symbol ratio (Actual FSR)
calculated from the counts obtained in the last deci-second. This value is
available even when accumulation is turned off.
[P]FETCh[:SENSe[1]]:FSRatio[:ALL][:FULL]:DELTa?
How to Evaluate Data Rate Ratio Results
You can use the following commands/queries to evaluate Data Rate Ratio results:
1
The following query returns the ratio of the number of filler Symbol count to
the expected filler symbol count received in the current (or last completed)
accumulation period, specified by the gate period.
