INSTRUMENT SETUP STORES
Twelve non-volatile
memories
are
provided
in the
5500
to store
instrument
setups.
Two
positions
are
reserved for
power-on
default
state and last
power-down
state
respectively
while the
remaining
ten
positions
are user
accessible.
The
instrument
normally powers up
in a
factory
defined default state stored in
memory
position
0.
This clears
any
unusual
settings
and assures the user of a known
start
configuration.
A list of the
position
0
default
states
is
given
in Section
2.6.
(Alternatively,
the instrument can be
changed
to
power
up
in
Memory
1
state,
use SPCL FNCT
23.1.
See
the note on
the next
page.)
Position 1 is the
complete
state of the instru-
ment
when
power
was last
turned off.
Positions 2
through
1 1 are
ten user definable
memories for convenient
recall of
special
test
setups.
Note that the
instrument
always
stores its
complete
status,
that
is,
everything
that can
be set
by'
the front
panel,
in the selected
memory.
The user
may
subsequently
elect to
request
either a
partial
recall,
that
is,
Only
the
frequency
and
amplitude
of the
oscillator or
a total recall.
To recall a total instrument
setup, key
in a
number from
0
to
11,
the decimal
point,
the
digit
1
then
terminate with the
RECALL
key.
For
example:-
-
Iflfi-
This will effect a total
recall of
what the user
previously
stored in
memory
4
(if
nothing
has
been
stored,
error
6
is
generated).
For a
partial recall,
omit the
decimal and
digit
1.
That
is,
4 RECALL will
recall
only
the
fre-
quency
and
amplitude
of the
generator
pre-
viously
stored in
position
4.
To store the
current status of the
instrument,
key
in a
number from 2 to
11 followed
by
the
STORE terminator
(STORE
is a
shifted ver-
sion of
RECALL).
E_W
Remember the
instrument
always
does a
total
store but the
user
may
elect either a
partial
or
total recall.
User available
storage
positions
are
2
through
11. Positions
0 and 1
are
automatically
stored and
only
available
for
user recall.
Note
:
When
recalling
a
complete
instrument state
(i.e.
2.1
through
11.1),
the
current instrument
state is
automatically
stored
in
memory
1
prior
to the total
recall.
(This
does
not occur
on a
partial
recall
-
2 to
11.)
Thus it is
possible
to alternate
between a
just
used
setup
and a
previously
stored
setup.
Or,
if the
recalled
memory
inadvertently
contains
an unwanted
instrument
setup,
the
operator
can
quickly
return to
the
previous
state
by keying
in
1.1
RCL.
The
storing
of
the
complete
instrument state
in
position
1
at
power
down is
only guaran-
teed if the
instrument is
powered
down
using
the front
panel
POWER
push
button. If
power
down
is
effected
by
removal of
mains
