BEFORE OPERATING
INTRODUCTION
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/microse-
cond
in
the
Fast mode.
The
remaining
features are
identical.
Storage
viewtime is
greater
than
15 seconds at
full-stored
display
intensity-extending
to
more than 6
minutes
using
reduced
intensity
in the Save mode.
The
dual-channel
dc-to-100
MHz
vertical system
provides
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
second
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
consumption
is
about
100 watts.
The
Tektronix
DM44
Digital
Multimeter
measures 0
ohm
to 20 megohms, 0 de
volt
to
1200
de
volts(+
or-),
or
,,
(using the temperature probe)
-55°C
to
+150°C.
The
measurement is displayed
on
a
3-1/2
digital
display
while
the
oscilloscope operates
normally.
The digital
multimeter
and
oscilloscope
combine
to
provide a digital readout
of
the
time
between any
two
points
on the oscilloscope display.
Both
time
measure-
ment
points are displayed on the
crt
at
the
same time.
The
1/TIME
function
can
provide
direct
measurement
of
frequency.
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.
