(coni)
To
provide
the interrupt,
the
Bit-Serial
Interface
(Option -06)
and
the Parallel Interface
(Option
-07)
transmit a single
"OR".
The
IEEE-488
Interface
(Option
-05)
provides an
interrupt
by generating
a service
request (SRQ).
The
reading triggered
by
the
"@"
character can be
obtained by inserting a
"G"
(get)
command
in
the
following
command
string
(terminated by
a
"?").
The
character
and
the
IEEE-488 Bus
command
"Group Execute
Trigger
"
perform the
same
function.
Command
characters
are classified
within the following
five
groups:
1.
FUNCTION
3.
MODIFIERS
2.
RANGE
4.
CONTROL
5.
MEMORY
There
are 7 function
command
characters.
Whenever
one
of
these characters
is
used, the state of the
instrument
will
be
changed
as
follows:
RANGE
Auto
MODIFIERS
Offset,
Scaling, Limits,
Peaks modes
are
