• The second value of the tuple is the accumulation of the the error
bits count (Accumulated Number of Errors) for all terminals of the
whole port.
(@4) specifies terminal 4.
(@3:5,9) specifies terminals 3, 4, 5 and 9.

If you have a finite sequence and are interested in the final result, you
should query the system state before trying to fetch the error rate
results. With the command :sgen:glob:syst:stat? you can check when
the system has FINished the sequence generation. Then stop the
system by :sgen:glob:init:cont OFF. Now it is save to fetch the error rate
results.
If you have an infinite sequence or want intermediate results anyway,
you can query the error results an any time. You always get the
number of received bits and the number or erroneous bits. If you
query soon after start, it can happen that the number of received bits
is 0. Then, of course, the number of errors is also 0. Ignore these
results and query again.
