OPERATORS SAFETY SUMMARY
The general safety information in this part of the summary is for both operating and servicing personnel. Specific warnings
and cautions willbe found throughout themanual wherethey apply and do not appear in this summary.
Terms in This Manual
CAUTION statements identify conditions or practices
that could result in damage to the equipment or other
property.
WARNING statements identify conditions or practices
that could result in personal injury or loss of life.
Terms as Marked on Equipment
CAUTION indicates a personal injury hazard not imme-
diately accessible as one reads the markings, or ahazardto
property, includingthe equipment itself.
DANGER indicates a personal injury hazard immediately
accessible as one reads the marking.

This symbol indicates where applicable
cautionary or other information
is to be
found. For maximum input voltage
see
Table 1-1.
Marked on Equipment
DANGER - High voltage.
Protectiveground (earth)terminal.
ATTENTION
- Referto manual.
Power Source
This product is intended to operate from a power source
that does not apply more than
250 volts rms between the
supply conductors or between either supply conductor and
ground. A protective ground connection by way of the
grounding conductor in the power cord
is essential for safe
operation.
Groundingthe Product
This product is grounded through the grounding conductor
of the power cord. To avoid electrical shock, plug the
power cord into a properly wired receptable before con-
necting to the product input or output terminals. A
protective ground connection by way of the grounding
conductor inthe power cord
is essential for safe operation.
Danger Arising From Loss of Ground
Upon loss of the protective-ground connection, all acces-
sible conductive parts (including knobs and controls that
may appear to be insulating)can render an electric shock.
Use the Proper Power Cord
Use only the power cord and connector specified for
your product.
Use only apower cord that is ingood condition.
For detailed information on power cords and connectors
see Figure
2-2.
Use the Proper Fuse
To avoid fire hazard, use only a fuse of the correct type,
voltage rating and current rating as specified in the parts
list for your product.
Do Not Operate in Explosive Atmospheres
To avoid explosion, do not operate this product in an
explosive atmosphere unless
it has been specifically cer-
tified for such operation.
Do Not Remove Covers or Panels
To avoid personal injury, do not remove the product
covers or panels. Do not operate the product without the
covers and panels properly installed.

SERVICING SAFETY SUMMARY
FOR QUALIFIED SERVICE PERSONNEL ONLY
Refer also to thepreceding OperatorsSafety Summary.
Do NotService Alone
Do not perform internal service or adjustment of this
product unless another person capable of rendering first
aid and resuscitation
is present.
Use Care When Servicing With Power On
Dangerous voltages exist at several points in this product.
To avoid personal injury, do not touch exposed connec-
tions or componentswhile power
is on.
Disconnect power before removing protective panels,
soldering, or replacingcomponents.
Power Source
This product is intended to operate from a power source
that does not apply more than
250 volts rms between the
supply conductors or between either supply conductor
and ground.
A protective ground connection by way of the
grounding conductor in the power cord
is essential for
safe operation.

The 2336 Oscilloscope.

Section 1-2336 Service
SPECIFICATION
This section of the manual contains a general description of instrument features, identifies standard accessories, provides
option information, and
lists the instrument specification.
INTRODUCTION
The TEKTRONIX 2336 Oscilloscope is a rugged, light-
weight, dual-channel, 100-MHz instrument having a com-
pact crt that provides a sharply defined trace. Its vertical
system supplies calibrated deflection factors from 5 mV per
division to 5 V per division. Sensitivity can be increasedto
at least 2 mV per division by the variable VOLTSIDIV
VAR control. Trigger circuits enable stable triggering over
the full bandwidth of the vertical system. The horizontal
system provides calibrated sweep speeds from 0.5
s per
division to 50 ns per division, along with delayed-sweep
features, thus accommodating accurate relative-time
measurements. A XI0 magnifier circuit extends the maxi-
mum sweep speed to 5 ns per division when the SECIDIV
switch
is set to0.05 ps per division.
A
3 112-digit LCD (liquid-crystal display) readout
enables rapid measurement of time difference between any
two points on the oscilloscope display. Both time measure-
ment points are displayedsimultaneously on the crt screen.
ACCESSORIES
The instrument is shipped with the following standard
accessories:
Probe packages
Accessory pouch
Operatorsmanual
Service manual
Accessory pouch, zip lock
Crt filter, clear plastic
1.0-A AGC fast-blow fuses
0.5-A AGC fast-blow fuse
For part numbers and further information about acces-
sories, refer to the "Accessories" page at the back of this
manual. Your Tektronix representative or local Tektronix
Field Office can also provide accessories information.
AVAILABLE OPTION
Option 03 (100-Vl200-V Power Transformer) permits
operation of the instrument from either a 100-Vor a200-V
nominal ac-power-input source at a line frequency from
48
Hz to440 Hz.
PERFORMANCE CONDITIONS
The following electrical characteristics (Table 1-1)
are valid for the 2336 when
it has been adjusted at an
ambient temperature between +20°c and +30°c, has had
a warmup period of at least 20 minutes, and
is operating
at an ambient temperature between -15'~ and +55'~
(unlessotherwise noted).
Items listed inthe "Performance Requirements" column
are verifiable qualitative or quantitative limits that may be
checked by procedures contained in the "Performance
Check" section of the manual (see Section
4), except as
noted. Performance check procedures for items listed in
the "Supplemental Information" column are not provided;
items in this column are either explanatory notes, perform-
ance characteristics for which no absolute limits are
specified, or characteristicsthat are impractical to check in
routine maintenance.
Environmental characteristics of the 2336 are given in
Table 1-2. All environmental tests performed meet the
requirements of MI
L-T-28800B, Type
II I, Class 3 equip-
ment, except where otherwise noted.
Physical characteristics of the instrument are listed in
Table 1-3, and option electrical characteristicsare presented
inTable 1-4.
