OPERATORS SAFETY SUMMARY
The general safety information in this part of the summary is for both operating and servicing personnel. Specific warnings
and cautions will be found throughout the manual where they 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
immediately accessi le as one reads the markings, or a
hazard to property, including the equipment itself.
DANGER indicates a personal injury hazard immedi
ately accessi le as one reads the marking.
Symbols in This Manual
A This sym ol indicates where applica le
cautionary or other information is to e
found. For maximum input voltage see
Ta le 5.
Symbols as Marked on Equipment
DANGER — High voltage.
Protective ground (earth) terminal.
ATTENTION — Refer to manual.

Power Source
This product is intended to operate from a power
source that does not apply more than 250 volts rms
etween the supply conductors or etween either supply
conductor and ground. A protective ground connection
y way of the grounding conductor in the power cord is
essential for safe operation.
Groundin the Product
This product is grounded through the grounding con
ductor of the power cord. To avoid electrical shock, plug
the power cord into a properly wired recepta le efore
connecting to the product input or output terminals. A
protective ground connection y way of the grounding
conductor in the power cord is essential for safe operation.
Dan er Arisin From Loss of Ground
Upon loss of the protective-ground connection, all
accessi le conductive parts (including kno s and controls
that may appear to e insulating) can render an electric
shock.
Use the Proper Power Cord
Use only the power cord and connector specified for
your product.
Use only a power cord that is in good condition.
For detailed information on power cords and con
nectors see Figure 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 een specifically
certified 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.

INTRODUCTION
The TEKTRONIX 2337 Oscilloscope is a rugged, light
weight, dual-channel, 100-MHz instrument with a general-
purpose digital multimeter (DMM). It also features a
compact crt that provides sharply defined traces. The
vertical system supplies cali rated deflection factors from
5 mV per division to 5 V per division. Sensitivity can e
increased to at least 2 mV per division y the varia le
VOLTS/DIV VAR control. Trigger circuits ena le sta le
triggering over the full andwidth of the vertical system.
The horizontal system provides cali rated 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 X10 magnifier circuit
extends the maximum sweep speed to 5 ns per division
when the SEC/DIV switch is set to 0.05 ps.
A 3 1/2-digit LCD (liquid crystal display) readout
ena les rapid measurement of time difference etween any
two points on the oscilloscope display.
The DMM portion measures dc voltage, resistance, and
true rms ac voltage. Measurement values are displayed on
the LCD readout, together with polarity, overrange, and
function indicators.
The instrument is shipped with the following standard
accessories:
2 Pro e packages
1 Accessory pouch
1 Operators manual
1 Service manual
1 Accessory pouch, zip lock
1 Crt filter, clear plastic
2 1,0-A AGC fast- low fuses
1 0.5-A AGC fast- low fuse
1 Pair test leads
For part num ers and further information a out oth
standard and optional accessories, refer to the "Acces
sories" page at the ack of this manual. Your Tektronix
representative or local Tektronix Field Office can also
provide accessories information.
