BEFORE
OPERATING
INTRODUCTION
This
Operators
Manual
provides
information
necessary
to
operate
the
instrument.
Included
are
power
require-
ments;
functions
of
controls,
connectors
and
indicators;
and
methods
for
making
several
different
measurements
of
electrical
phenomena.
Also
included
is
a
procedure
for
checking
basic
instrument
calibration.
The
Tektronix
466
and
464
are
dual-channel
portable
oscilloscopes.
The
466
storage
system
provides
storage
for
displays
with
a
writing
speed
up
to
3000
divisions/
microsecond
(in
the
Fast-Reduced
Scan
mode).
The
464
storage
system
does
not
have
the
reduced
scan
mode
and
the
writing
speed
is
up
to
110
divisions/microsecond
in
the
Fast
mode.
The
remaining
features
are
identical.
Storage
view-
time
is
greater
than
15
seconds
at
full-stored
display
in-
tensity—extending
to
more
than
6
minutes
using
reduced
in-
tensity
in
the
Save
mode.
The
dual-channel
DC-to-100
MHz
vertical
system
pro-
vides
calibrated
deflection
factors
from
5
millivolts
to
5
volts/division.
The
sweep
trigger
circuits
are
capable
of
stable
triggering
over
the
full
bandwidth
capabilities
of
the
vertical
deflection
system.
The
horizontal
deflection
system
provides
calibrated
sweep
rates
from
0.5
seconds
to
0.05
microsecond/division
along
with
delayed
sweep
features
for
accurate
relative-time
measurements.
A
X10
magnifier
extends
the
calibrated
sweep
rate
to
5
nanoseconds/
division.
The
instrument
operates
over
a
wide
variation
of
line
voltages
and
frequencies.
Maximum
power
consump-
tion
is
about
100
watts.
OPERATING
VOLTAGE
This
instrument
operates
from
either
a
115-volt
or
a
230-volt
nominal
line
voltage
source,
48
to
440
hertz.
The
line
voltage
selector
switch
must
indicate
the
applied
line
voltage
(115
V
or
230
V).
The
regulating
range
selector
(Item
52,
Controls,
Con-
nectors
and
Indicators)
must
indicate
the
regulating
range
for
the
applied
operating
line
voltage.
SAFETY
INFORMATION
The
instrument
is
designed
to
operate
from
a
single-
phase
power
source
with
one
of
the
current-carrying
conductors
(the
Neutral
Conductor)
at
ground
(earth)

potential.
Operation
from
power
sources
where
both
current-carrying
conductors
are
live
with
respect
to
ground
(such
as
phase-to-phase
on
a
three-wire
system)
is
not
recommended,
since
only
the
Line
Conductor
has
over-
current
(fuse)
protection
within
the
instrument.
The
instrument
has
a
three-wire
power
cord with
a
three-terminal
polarized
plug
for
connection
to
the
power
source
and
safety-earth.
The
ground
(earth)
terminal
of
the
plug
is
directly
connected
to
the
instrument
frame.
For
electric-shock
protection,
insert
this
plug
only
in
a
mating
outlet
with
a
safety-earth
contact.
NOMINAL
LINE
VOLTAGE
RANGE
This
instrument
may
be
damaged
if
operated
with
the
line
voltage
selector
switch
or
the
regulating range
selector
set for
the
wrong
applied
line
voltage.
To
convert
from
one
nominal
line
voltage
range
to
the
other,
move
the
Line
Voltage
Selector
switch
(located
on
side
panel)
to
indicate
the
correct
nominal
voltage.
A
115-to-230
volt
adapter
may
be
required
for
the
line-cord
plug.
The
Regulating
Range
Selector
assembly
(located
on
the
rear
panel)
is
set
for
one
of
the
