Upon
power-up,
or
after receiving a DCL, SOC,
or
JOX
command, the instrument de-
faults to
G1,0,0
(de source values
in
ASCll format
with
prefix
and
suffix).
Whenever the instrument
is
addressed to talk,
it
sends one
or
more lines of its
output
data
over the IEEE-488
bus
to
the controller. The format
of
output
data
is
determined
by
how
it
is
configured
with
the G command. Figure 3-3 shows
an
example of
an
ASCll
output
data
string
that
includes all items,
and
is formatted for
both
prefix
and
suffix. Figure 3-4 shows the binary formats for all items selected.
