FETCH[:SENSe[1]]:ERATio
This is a contraction of the phrase “Error RATio” and is the ratio of the number of errors
to the number of bits received in a time interval, specified by the next level in the
command. The next level is:
[:ALL][:FULL][:TOTal]? <NR3> The error ratio calculated from the total clock and bit
error counts accumulated since the start of the gating
period.
[:ALL][:FULL]:DELTa? <NR3> The “instantaneous” error ratio calculated from the
counts obtained in the last decisecond. This value is
available even when gating is turned off.
[:ALL]BIT [:TOTal]? <NR3> The error ratio calculated on the currently configured
“BIT: Error address” since the start of the gating
period.
[:ALL]BIT:DELTa? <NR3> The error ratio over the last decisecond on the currently
selected bit.
:ZASone[:TOTal]? <NR3> This is a contraction of the phrase Zero received AS
One. The command returns the error ratio calculated
from a count of errors, where each error is a true data
zero received as a data one.
:OASZero[:TOTal]? <NR3> This is a contraction of the phrase One received AS
Zero. The command returns error ratio calculated from
a count of errors, where each error is a true data one
received as a data zero.
FETCH[:SENSe[1]]:EINTerval
This is a contraction of the phrase Errored INTerval and returns a count of the number of
time intervals, the duration of which is selected by the next node, in which one or more
errors were detected. The four time interval classifications are:
:SEConds? <NR3> One second
:DSEConds? <NR3> One decisecond
:CSEConds? <NR3> One centisecond
:MSEConds? <NR3> One millisecond
