IAgilentN490xEDErrorRatio.Read (IVI-compliant)

[P]FETCh[:SENSe[1]]:ERATio[:ALL][:FULL][:TOTal]?

This query is a contraction of the phrase Error Ratio. It returns the ratio of the

number of errors to the number of bits received in the current (or last completed)

accumulation period, specified by the gate period.

[P]FETCh[:SENSe[1]]:ERATio[:ALL][:FULL]:DELTa?

IAgilentN490xEDErrorRatio.ReadDelta (IVI-compliant)

[P]FETCh[:SENSe[1]]:ERATio[:ALL][:FULL]:DELTa?

This query returns the "instantaneous" error ratio (Actual BER) calculated from

the counts obtained in the last deci-second. This value is available even when

accumulation is turned off.
