[P]FETCh[:SENSe[1]]:FSRatio[:ALL][:FULL][:TOTal]?
4
The following query returns the "instantaneous" SKPOS Bit Ratio calculated
from the counts obtained in the last deci-second. This value is available even
when accumulation is turned off.

How to Evaluate Data Rate Ratio Results
You can use the following queries to evaluate Data Rate Ratio results:
1
The following query returns the ratio of the number of SKPOS bit count to the
expected SKPOS bit count received in the current (or last completed)
accumulation period, specified by the gate period.
[P]FETCh[:SENSe[1]]:DRRatio[:ALL][:FULL][:TOTal]?
2
The following query returns the "instantaneous" data rate ratio (Actual DRR)
calculated from the counts obtained in the last deci-second. This value is
available even when accumulation is turned off.
[P]FETCh[:SENSe[1]]:DRRatio[:ALL][:FULL]:DELTa?
How to Evaluate Modified SKPOS Count Results
You can use the following queries to evaluate Modified SKPOS Count results:
1
The following query returns total number of SKPOS count whose length has
been changed by DUT in a time interval.
[P]FETCh[:SENSe[1]]:MSCount[:ALL][:FULL][:TOTal]?
2
The following query returns the “instantaneous” number of Modified SKPOS
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]]:MSCount[:ALL][:FULL]:DELTa?
How to Evaluate Expected SKPOS Count Results
The following query returns total number of Expected SKPOS Count received in a
time interval.
[P]FETCh[:SENSe[1]]:ESCount?
How to Evaluate Auto Re-Sync Count Results
The following query returns total number of Auto Re-Sync Count received in a time
interval.
