Manual
CAUTION statements identify conditions or practices that
could result in damage to the equipment or other property .
Grounding
the
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
receptacle
before connecting
to
the product input
or output
terminals . A
protective ground
connection by way of the grounding conductor in the power
cord is essential for safe operation .
WARNING statements identify conditions or practices that
could result in
personal injury or
loss of life .
Terms

CAUTION indicates a personal injury hazard not immediate
ly accessible as one reads the markings , or a hazard to
property
, including
the
equipment
itself
.
Upon loss
of the
protective -
ground connection
, all
accessi
ble conductive parts ( including knobs and controls that may
appear
to
be
insulating )
can render
an
electric
shock .
DANGER indicates a personal injury hazard immediately ac

Do Not Remove Covers or Panels
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
.
To avoid personal injury , do not remove the product covers

The
TEKTRONIX 2236
oscilloscope
is
a
lightweight 100
MHz instrument with a Counter , Timer , and Multimeter
( CTM ) . Measurement values are displayed on the Vacuum
Fluroescent nine - digit readout .
For part
numbers and further
information about
both stan
dard and optional accessories , refer to the " Options and
Accessories " section ( Section 5 ) of this manual . Your
Tektronix
representative ,
local
Tektronix Field
Office , or
Tektronix product catalog can also provide accessories
information .
The dual vertical channel system supplies calibrated deflec
tion factors from 2 mV per division to 5 V per division . Trig
ger circuits enable stable triggering over the full bandwidth
of the vertical system . The horizontal system provides cali
brated sweep speeds from 0.5 s per division to 50 ns per
division , along with delayed - sweep features . A X10 magnifi
er
circuit
extends
the
maximum
sweep
speed
to
5 ns
per
division when the A and B SEC / DIV switch is set to 0.05 us .
SPECIFICATION
The following electrical characteristics ( Table 1-1 ) are valid
for the 2236 when it has been adjusted at an ambient tem
perature between + 20 ° C and + 30 ° C , has had a warm - up
period of at least 30 minutes , and is operating at an ambient
temperature
between
° C and
+ 50 ° C (
unless
otherwise
noted ) .
The
Counter
Timer
section of the CTM
measures
frequency ,
period , width , and totalizes , and provides a digital readout
of oscilloscope delay time and delta time . It also provides
frequency , period , and width measurements and totalizes
on portions of a waveform selected by the intensified zone
( gated measurements ) . Counting and timing measurements
are made through the A and B Trigger system . All Counter
Timer measurement values are displayed on the readout .
Items listed in the “ Performance Requirements " column are
verifiable
qualitative or
quantitative limits
, while items
listed
in the " Supplemental Information ” column are either explan
atory notes , calibration setup descriptions , performance
characteristics for which no absolute limits are specified , or
characteristics that are impractical to check .
П
Л 1
The
Multimeter
section
of
the CTM
measures
voltages and
resistance through the floating input connectors located on
the right side of the instrument . Voltages can also be mea
sured
through the CH 1
or X & DMM
connector
.
Tempera
ture
measurements can
be made by
connecting
the
optional
temperature probe to the Multimeter input connectors . The
Multimeter measurement values are displayed with a 3 3 / 4
digit ( 5000 count ) format , on the digital readout .
Environmental characteristics are given in Table 1-2 . The
2236 meets the
requirements of MIL - T - 28800C
,
paragraphs
4.5.5.1.3 , 4.5.5.1.4 , and 4.5.5.1.2.2 for Type III , Class 5
equipment
,
except
where otherwise
noted .
