Address/Channel List Parameter
There are two ways to specify the U2722A/U2723A address or channel list 
parameter. To specify a single channel, use the following syntax.
(@<ch>)
For example, CURR 0.02, (@1), where (@1) specifies channel 1.
To specify a single address, use the following syntax.
(@<address>)
For example, CONF:SSI SLAV, (@1), where (@1) specifies address 1.
To specify more than one address, the following syntax must be used.
(@<address>[,<address>])
– The command CONFigure:SSI is the only U2722A/U2723A command that 
uses the range of address list.
– When adding a channel list parameter to a query, you must include a space 
character between the query indicator (?) and channel list parameter. 
Otherwise error –103, “Invalid separator” will occur.
