When you specify a range of channels, the first and last channel in the
range must be valid and any channel within the range that is invalid will
be ignored (no error will be generated). Query results are returned in the
order they are specified in the list.
NOTE
When adding a channel list parameter to a query, you must include a space character
between the query indicator (?) and channel list parameter such as ROUT:CLOS?
(@<ch_list>). Otherwise error –103, ''Invalid separator'' will occur.
