SET
THE

to
the
ON
position.
If

lindicaior
does
not

within
1
minute,set
the
Rear

Troubleshooting
and

is
indicated.

When
the
STBY
POWER
indicator
turns
on,
the
instrument
is
in
the
standby
condition.
The
607X4-130
Oven
Reference
Option
and
the
607XA-570
Non-
Volatile
Memory
Options,
if
installed,
receive
power
in
standby.
No
other
instrument
circuit
receives
power
during
standby.

RF
EMISSION
CONTROL
3-8.
For
applications
which
are
sensitive
to
RF
emissions,
it
is
recommended
that
BNC
open
termination
units
be
installed
on
all
unused
rear
panel
connectors.

IEEE-488
3-10.
Eiecirical
Connection
3-11.
The
IEEE-488
Connector
(rear
panel)
mates
with
any
standard
24-conductor
iEEE-488
cable.
Figure
3-2
shows
the
pin-outs
on
the
connector.
IEEE-488
system
connections
must
not
exceed
the
following
limits;
1.
No
more
than
15
devices
may
be
connected
in
a
single
IEEE-488
Bus
system.
2.
The
total
length
of
cable
used
in
one
IEEE-488
Bus
system
must
not
exceed
20
meters.
3.
The
total
length
of
cable
must
also
not
exceed
2
meters
times
the
number
of
devices
in
the
system.
3-12.
Table
3-2
lists
IEEE
Standard
Cables
available
from
Fluke
in
lengths
of
i,
2,
and
4
meters.
Combinations
of
these
cables
can
be
used
to
meet
the
IEEE-488
Bus
system
cable
restrictions.
For
example,
when
only
the
signal
generator
is
connected
to
a
controller,
the
number
of
devices
is
2.
According
to
limit
3,
the
total
length
of
cable
must
not
exceed
two
meters
times
the
number
of
devices.
So,
the
total
length
of
cable
must
be
4
meters
or
less.
Therefore,
any
one
of
the
accessory
cables
can
be
used
to
connect
the
two
instruments.
3-13.
IEEE-488
INTERFACE
Switches
3-14.
The
positions
of
the
IEEE-488
INTERFACE
switches
(rear
panel)
determine
the
IEEE-488
address
of
the
instrument
and
determine
whether
the
instrument
is
both
a
talker
and
a
listener
or
just
a
listener.
Set
the
LISTEN
ONLY
switch
to
the
ON
(up)
position
to
make
the
instrument
just
a
listener.
Set
the
LISTEN
ONLY
switch
to
the
OFF
(down)
position
to
make
the
instrument
both
a
talker
and
a
listener.
The
positions
of
the
five
switches
al
through
a5
determine
the
IEEE-488
address
of
the
instrument.
The
IEEE-
488
address
is
the
same
for
both
the
listener
and
the
talker
functions.
Set
the
switches
to
the
positions
indicated
in
Table
3-3
for
the
desired
address.
If
LISTEN
ONLY
is
al
the
ON
position,
the
instrument
is
always
addressed,
so
the
positions
of
al
through
a5
will
have
no
meaning.
