Since
*OPC?
waits until all previous commands are executed, "
1
" is returned in all cases.
*OPC?
basically functions like the
*WAI
command, but *
*WAI
does not return a response.
*OPC?
is preferred to
*WAI
because with
*OPC?
, the execution of commands can be
queried from a controller program before new commands are sent. This avoids an over-
flow of the input queue when too many commands are sent that cannot be executed.
Unlike
*WAI
,
*OPC?
must be sent at the end of a program message.
*OPT?
OPT ion identification query returns a list of the options installed. The options are sepa-
rated from each other by means of commas.
Option Response string

Example: *OPT?
