Channel lists are used as a way of listing multiple values. Channel lists
are enclosed in parenthesis and start with the ASCII '@' character.
The values are separated with commas. The length of the channel list
is determined by the unit. A range of values can be indicated by the
two end values separated by a colon. e.g.
(@1,2,3,4)
lists sequential values
(@ 1:4)
shows a range of sequential values
(@ 1,5,7,34)
lists random values

A1.3.4 Error Reporting
SCPI provides a means of reporting errors by responses to the
SYST:ERR?
query. If the SCPI error queue is empty, the unit
responds with 0, "No error" message. The error queue is cleared at
power turn-on, by a
*CLS
command or by reading all current error
messages. The error messages and numbers are defined by the SCPI
specification and are the same for all SCPI devices.
A1.3.5 Additional Information
For more information about SCPI refer to the SCPI Standard or to the
SCPI section in any SCPI compatible instrument manual.
