Section 1— 2236 Service
SPECIFICATION
INTRODUCTION ACCESSORIES
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.
The dual vertical channel system supplies calibrated de­
flection factors from 2 mV per division to 5 V per division.
Trigger circuits enable stable triggering over the full band­
width 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. A X10 magni­
fier circuit extends the maximum sweep speed to 5 ns per
division when the A and B SEC/DIV switch is set to 0.05 ns.
The Counter Timer section of the CTM measures fre­
quency, 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 intensi­
fied zone (gated measurements). Counting and timing mea­
surements are made through the A and B Trigger system.
All Counter Timer measurement values are displayed on the
readout.
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
measured through the CH 1 or X & DMM connector. Tem­
perature measurements can be made by connecting the op­
tional temperature probe to the Multimeter input
connectors. The Multimeter measurement values are dis­
played with a 3 3/4-digit (5000 count) format, on the digital
readout.
The instrument is shipped with the following standard
accessories:
1 Operators manual 2 Multimeter test lead clips
1 Probe package 2 Multimeter test leads
1 Power cord
For part numbers and information about instrument ac­
cessories, refer to the tabbed “Accessories” part of the Re­
placeable Mechanical Parts section in the back of this
manual.
The service manual and all other optional accessories are
orderable from Tektronix, Inc. A local Tektronix Field Office,
representative, or the Tektronix product catalog can provide
ordering and product information.
PERFORMANCE CONDITIONS
The following electrical characteristics (Table 1-1) are
valid for the 2236 when it has been adjusted at an ambient
temperature between + 18°C and +28°C , has had a warm­
up period of at least 30 minutes, and is operating at an
ambient temperature between 0°C and +50°C (unless oth­
erwise noted).
Items listed in the “Performance Requirements" column
are verifiable qualitative or quantitative limits, while items
listed in the “Supplemental Information" column are either
explanatory notes, calibration setup descriptions, perfor­
mance characteristics for which no absolute limits are speci­
fied, or characteristics that are impractical to check.
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.
Physical characteristics of the instrument are listed in Ta­
ble 1-3.
