BEFORE OPERATING

INTRODUCTION

The

Tektronix

466 and 464 are

dual-channel

portable

oscilloscopes.

The

466

storage

system

provides

storage

for

displays

with

writing

speed

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

110

divisions/microse-

cond

the

Fast mode.

The

remaining

features are

identical.

Storage

viewtime is

greater

than

15 seconds at

full-stored

display

intensity-extending

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

millivolts

volts/division.

The

sweep

trigger

circuits

are capable

stable

triggering

over

the

full

bandwidth

capabilities

the

vertical

deflection

system.

The

horizontal

deflection

system

provides

calibrated sweep rates

from

0.5

second

0.05

microsecond/division

along

with

delayed sweep

features

for

accurate

relative-time measurements. A X10

magnifier

extends the

calibrated

sweep rate

nanoseconds/division.

The

instrument

operates over a

wide

variation

line voltages and frequencies.

Maximum

power

consumption

about

100 watts.

The

Tektronix

DM44

Digital

Multimeter

measures 0

ohm

to 20 megohms, 0 de

volt

1200

volts(+

or-),

(using the temperature probe)

-55°C

+150°C.

The

measurement is displayed

3-1/2

digital

display

while

the

oscilloscope operates

normally.

The digital

multimeter

and

oscilloscope

combine

provide a digital readout

the

time

between any

two

points

on the oscilloscope display.

Both

time

measure-

ment

points are displayed on the

crt

the

same time.

The

1/TIME

function

can

provide

direct

measurement

frequency.

SAFETY INFORMATION

The instrument is designed

operate

from

single-

phase power source with

one

the

current-carrying

conductors

(the Neutral

Conductor)

ground

(earth)

potential. Operation from

power

sources where both

current-carrying

conductors

are live

with

respect

ground

(such as phase-to-phase on a

three-wire

system)

not

recommended, since

only

the

Line

Conductor

has

over-current

(fuse)

protection

within

the

instrument.
