Use this command to define the offset within the data block where the loop
occurs. E.g. If the data pattern is defined as 11101010 and loop offset is
defined as 5 then the following output will be generated:
11101010010010010010010…
The query form always returns the loop offset of the currently selected
pattern – which is not necessarily identical with the loop offset previously
set with the :DIG:LOFF command. This parameter will automatically be
updated when loading a data pattern from non-volatile storage or when
defining a new pattern using the local user interface.
