SECTION 2
OPERATING
INSTRUCTIONS
Change
information, if
any, affecting
this section
will
be found at
the
rear
of this
manual.
General
To
effectively
use
the 5103N,
the operation and capa-
bilities
of the
instrument
must
be known. The 5103N
Power
Supply/Amplifier
module
forms the basis
of
an
oscil-
loscope
system,
and
requires a
display
module and plug-ins
to
complete
the system.
This
section
describes inter-
connection
and
general
operation
of
the
units, including
preliminary
information
for first-time
turn-on,
selection
and
installation
of plug-ins,
general operating
information,
and some
basic
oscilloscope
applications.
Detailed
operating
information
for
a
specific
display
module or
plug-in is
given
in the
instruction
manual for that
unit.
PRELIMINARY
INFORMATION
Rackmounting
The
5103N
Power
Supply/Amplifier
module and
the dis-
play
module
can
be
fastened
together
stacked
or
side by
side,
permitting
operation
as a
bench
oscilloscope,
or it
can
be
operated
in a
standard
19-inch rack.
Complete
instruc-
tions
for
rackmounting
are
given
in Section
6,
Rack-
mounting.
NOTE
Before
attempting
to
operate
the
instrument,
make
sure
the
module
wiring
interconnections
are correct,
and
if
display
modules
have
been
changed,
that the
correct
auxiliary
board is
installed in
the
socket
on
the
plug-in
interface
board.
Operating
Voltage
This
instrument
is
designed
for operation
from a
power
source
with
its
neutral at
or near
earth
(ground)
potential
with a
separate
safety-earth
con-
ductor.
It is
not
intended
for
operation
from
two
phases
of
a
multi-phase
system,
or across
the legs
of
a
single-phase,
three-wire system.
The
5100-Series
Oscilloscope
is
operated
from a
1
15-volt
nominal
line
voltage
source (NOTE:
for
instrumentshaving
optional
export
transformer,
see
information
following
Table
2-1
).
The
power
transformer is wired
to
permit
either
of two
regulating
ranges to
be selected.
The range
for
which
the
primary taps
are set is
marked on the
rear panel
of the
instrument.
Use
the
following
procedure to
change regu-
lating
ranges:
1
.
Disconnect
the
instrument
from the
power source.
2.
Remove the
bottom
dust
cover
of the
instrument
to
gain access to
the
Power Supply
circuit board
.
3.
Remove the
brown
line-selector
block
from the
square-pin
connectors
(see Fig. 2-1)
and
place it
on
the
desired set
of pins
(use pins
marked H
or M
only).
Select a
range
which is
centered
about
the average
line
voltage
to
which
the
instrument is
to be
connected
(see Table
2-1
).
4.
Change
the
nominal
line
voltage
information
on
the
rear
panel of the
instrument. Use a
non-abrasive
eraser
to
remove
previous
data,
and
mark in
new data
with a
pencil.
5.
Replace
the
bottom
dust
cover and
apply
power to
the
instrument.
