Upon
power-up,
or
after receiving a
OCL
or
SOC command, the instrument defaults
to the
de
function
and
the
last progammed selection for source. A
JOX
command re-
stores factory default settings of
FO,O
(source
V,
de
function).
The F command selects the source
and
function. When programmed to source
V,
the
instrument measures
I
and,
conversely,
when
programmed
to source
I,
the
instru-
ment
measures
V.
When
programmed
for de, the instrument functions as a constant de source. De
func-
tion parameters are
programmed
with
the
B
command (see
paragraph
3.6.2). When
programmed
for sweeping, the instrument,
when
triggered, outputs a programmed
sweep (see
paragraph
3.6.15).
1.
Any
time the F command
is
executed, the Model236
/237/238
is
placed
in
an
un-
triggered state.
2.
Any time the
"source" parameter value
is
changed, the instrument
is
placed
in
standby.
3. Each source
(V
and
I)
will
remember its
own
unique
setup
configuration.

nents
