SECTION 1
INTRODUCTION
TM 9-6625-646-14&P
The 212 Oscilloscope is a dual-channel portable
oscilloscope using all solid state and integrated circuitr y
(except the CRT). The s m all size of the 212 m ak es it an
extremely portable oscilloscope for on-location
maintenance in many fields of application.
The 500 kilohertz vertical system provides vertical
deflection factors from one millivolt (at a reduced
bandwidth) to 50 volts/division at the tip of either of the
two integral high-impedance probes. Both single-trace
and dualtrace modes of operation are offered. Singletrace displays are achieved by turning off either ver tical
channel with its position control. In the dual-trace mode,
the instrument automatically chops or alternates,
depending upon the sweep rate. The trigger circuits
provide stable triggering over the full bandwidth
capabilities of the vertical system.
The horizontal deflection system provides calibrated
sweep rates from 500 millisec onds to five m icrosec onds/
division. It also provides uncalibrated sweep rates, via a
variable sweep magnifier, to at least five times the
indicated sweep rate for a maximum of at least one
microsecond/ division. In addition, X-Y operation is
provided. Channel 1 supplies the horizontal (X)
deflection, with a range from less than one millivolt to 50
volts/division (at a reduced bandwidth of 50 kilohertz),
and Channel 2 the vertical (Y) deflection. The resultant
CRT display is presented on a 6 X 10 divis ion graticule
(each division equals 0.203 inch).
The 212 is operated either from AC line voltage or
from internal rechargeable batteries. The internal
batteries are recharged from the AC power line by the
integral battery charger.
This instrument will meet the following electrical
characteristics after complete instrument calibration.
These characteristics apply over an ambient temperature
of -15àC to +55àC (+5àF to +131àF), except as
otherwise indicated. W armup time for given accuracies
is five minutes.

improvements to our instruments as soon as they are developed and tested.
Sometimes, due to printing and s hipping requirements, we can’t get these changes imm ediately into printed manuals.
Hence, your manual may contain new change information on following pages.
A single change may affect sever al sections. Since the change inform ation sheets are c arried in the manual until all
changes are permanently entered, some duplic ation may occur. If no such change pages appear following this page, your
manual is correct as printed.
SERVICE NOTE
Because of the universal parts procurement problem, some electrical parts in your instrument may be different
from those described in the Replaceable Electrical Parts List. The parts used will in no way alter or compromise
the performance or reliability of this instrument. They are installed when necessary to ensure prompt delivery to

FUNCTIONS OF CONTROLS AND CONNECTORS
TM 9-6625-646-14&P
The controls and connectors neces sary for operation
of the 212 are located on the right side of the instrument.
(See Fig. 2-1.) The POWER (BATTERY) indicator is on
the front panel. A brief description of each contr ol and
connector is given here.
VOLTS/DIV-selects vertical deflection factor (vertical
VARiable control must be in CAL position for
indicated deflection.
INPUT COUPLING-selects the method used to couple
the channel input signal to the vertical amplifier
system.
AC-the DC component of input signal is blocked.
GND-vertical amplifier input circuit is grounded.
The applied input signal is connected to ground
through a one megohm resistor to provide a
precharge path for the AC input coupling
capacitor.
DC-all components of the input signal are
passed to the vertical amplifier system input.
STEP ATTEN BALance-a screwdriver adjustment to
balance the vertical amplifier system for minimum
trace shift when switching deflection factors.
Vertical POSition-controls the vertical position of the
appropriate trace. OFF detent turns the channel
off.
VOLTS/DIV VARiable-provides a continuously variable
deflection factor between the calibrated settings of
the VOLTS/DIV switch for the appropriate vertical
channel.
VERTical GAIN-screwdriver adjustment to set the gain of
the vertical amplifier system.
AUTO PRESET-screwdriver adjustment to set the AUTO
PRESET trigger point for automatic trigger
operation.
Trigger SOURCE-selects the source of the trigger signal.
COMP-the sweep is triggered from a sample of
the vertical deflection signal after the vertical
switching.
CH 2-the sweep is triggered from a sample of
the vertical deflection signal before the vertical
switching and only from CH 2.
EXT-the sweep is triggered from the signal
applied to the EXT TRIG banana jack.
Figure 2-1. Side Panel controls and connectors.
2-1
LEVEL/SLOPE-selects the amplitude point and the s lope
of the trigger signal on which the sweep is triggered.
When the indicator dot is to the left of center, the
sweep is triggered on the positive-going slope of the
trigger signal; to the right of center, on the negative-
going slope. When the LEVEL/SLOPE control is set
to the AUTO PRESET detent, the sweep is
automatically triggered at a preset level on the
positive-going slope.
INTENSITY-controls brightness of CRT display.
TM 9-6625-646-14&P
Horizontal POSition-controls the horizontal position of the
trace.
SEC/DIV-selects horizontal sweep rate (HORIZ MAG
must be in CAL position for indic ated sweep rate) X-Y
position allows for X-Y operation; CH 2 supplies the
vertical deflection and CH 1 the horizontal deflection.
EXT TRIG-banana jack for input of an external trigger
signal.
SWP CAL-screwdriver adjustment to provide calibrated
sweep timing.
POWER-controls power to the instrument. Does not
interrupt charging current to the internal batteries
when the instrument is connected to an AC line
voltage.
FOCUS-screwdriver adjustm ent to obtain a well-defined
display.
HORIZontal MAGnifier-provides continuously variable
sweep magnification to a max imum of approxim ately
five times the sweep rate indicated by the SEC/DIV
switch.
HORIZontal GAIN-screwdriver adjustment to set the
basic gain of the horizontal amplifier system.
COMMON-banana jack to establish common ground
between the 212 and the external signal source or
equipment under test.
WARNING

SECTION 3
PREVENTIVE MAINTENANCE
Preventive maintenance, when performed on a
regular basis, can prevent instrument breakdown and
may improve the reliability of this instrument. The
severity of environment to which the 212 is subj ected will
determine the frequency of maintenance. A convenient
time to perform preventive maintenance is preceding
recalibration of the instrument.
Disassembly
To gain access to the interior of the instrument,
unwind both the probe cords and the power cord from
the rear of the instrument. Remove the five screws in
the bottom cover of the instrument. See Fig. 3- 1. G ently
separate the bottom cover from the instrument and lay
aside. The Power Supply circuit board with the batteries
can be lifted up and pivoted out of the way. Most of the
internal workings of the instrument are now accessible.
If it is necessary to have access to the front of the
Input circuit board, remove the knobs from all of the
external control shafts. Remove the four screws
securing the side panel to the Input circuit board and
remove the instrument side panel.
TM 9-6625-646-14&P
Cleaning
The 212 should be cleaned as often as operating
conditions require. Accumulation of dir t in the inst rument
can cause component breakdown.
The high impact plastic covers provide protection
against dust in the interior of the instrument. Loos e dust
accumulated on these covers can be removed with a soft
cloth or small brush. The brush is also useful for
dislodging dirt on and around the side-panel controls.
Dirt which remains can be removed with a soft cloth
dampened in a mild detergent and water solution.
Abrasive cleaners should not be used.
It should be only occasionally necessary to c lean the
interior. The best way to clean the interior is to blow off
the accumulated dust with dry, low-velocity air. A
softbristle brush or a cotton-tipped applicator is useful for
cleaning in narrow spaces or for cleaning more delic ate
circuit components.
Figure 3-1. Location of screws securing bottom cover and
side panel.
CAUTION
Avoid the use of chemical cleaning
agents which might damage the
plastics used in this instrument.
Avoid chemicals which contain
hydrochloric acid, sodium hydroxide,
or sulfuric acid.
Visual Inspection
The 212 should be inspected occasionally for such
defects as broken connections, improperly seated
transistors, damaged circuit boards, and heat-damaged
parts.
3-1
parts. The corrective procedure for most visible defects
is apparent; however, particular care must be taken if
heat-damaged components are found. Overheating
usually indicates other trouble in the instrument;
therefore, it is important that the cause of the
overheating be corrected to prevent recurrence of the
damage.
Semiconductor Checks
Periodically checking the semiconductors in the 212 is
not recommended. The best check of semiconductor
performance is actual operation in the instrument. If it is
desired to check the performance of a semiconductor
out of the instrument, a dynamic checker such as a
TEKTRONIX Type 576 Transistor Curve Tracer is
recommended. Lead configurations of the
semiconductors used in the 212 are shown in Fig. 5-2.
An extracting tool should be used to remove the 14-,
and 16-pin flat integrated circuits to prevent damage to
the pins. If an extracting tool is not available when
removing one of these integrated circuits, pull s lowly and
evenly on both ends of the device. Try to avoid having
one end of the integrated circuit disengage from the
socket before the other, as the pins may be damaged.
When replacing semiconductors, key the
semiconductor’s index with that of its soc ket. Failure to
do so can result in damaged components.
TM 9-6625-646-14&P
Recalibration
To assure accurate measurements, check the
calibration of this instrument after each 1000 hours of
operation or every six months if used infrequently. In
addition, replacement of components may necessitate
recalibration of the affected circuits. The calibration
procedure can also be helpful in localizing certain
troubles in the instrument. In some cases, minor
troubles may be revealed or corrected by recalibration.

Component Color Coding
The resistors used in this instrument are either
composition resistors or precision resistors. The
resistance values are color-coded on the components
with EIA color-code (some precision r esistors may have
the value printed on the body). The color-code is read
starting with the stripe nearest the end of the resistor.
Composition resistors have four stripes which c onsist of
two significant figures, a multiplier, and a tolerance value
(see Fig. 5-1). Precision resistors have five stripes
consisting of three significant figures, a multiplier, and a
tolerance value.
The capacitance values of common disc capacitors
and small tubular electrolytics are marked in mic rofarads
on the side of the component body. The molded
electrolytic capacitors ar e color-coded in picofarads (see

CIRCUIT DESCRIPTION
TM 9-6625-646-14&P
The following circuit description begins with a
discussion of the instrument using the block diagram
located in the Diagrams section at the rear of this
manual. Then each circuit is described in detail, using
detailed diagrams where necessary to show the
interconnections between the stages in each major
circuit and the relationship of the side-panel controls to
the individual stages. In addition to the block diagram,
complete schematics are given in the Diagrams section.
Block Diagram
Signals to be displayed on the CRT are applied to the
tips of the signal probes. The signals are then amplif ied
by the appropriate channel Input Amplifier circuit,
consisting of a two-section source-follower stage and two
feedback amplifiers. The Input Amplifier circuits also
contain the vertical deflection, position (with channel onOFF), input coupling, variable attenuation, and balance
controls.
The Trigger Generator circuit initiates the sweep
signal produced by the Sweep Generator. The input
signal to the Trigger Generator can be select ed internally
either from the capacitively coupled CH 2 Input Am plifier
signal, or from the direc tly coupled COMPosite signal of
the Feedback Amplifier. The Trigger Generator input
signal can also be selected from the external signal
applied to the EXT TRIG jack. The Trigger Generator
circuit contains coupling and sourc e controls in addition
to a combination level/slope control.
The Sweep Generator circuit produces a linear
sawtooth output signal when initiated by the Trigger
Generator circuit. The slope of the sawtooth signal is
controlled by the SEC/DIV switch. The Sweep Generator
circuit also produces an unblanking gate signal
coincident with the sawtooth waveform. This gate s ignal
unblanks the CRT to permit display presentation.
The output of U370 is amplified by the Horizontal
Amplifier circuit to produce the correct horizontal
deflection for the CRT for all positions of the SEC/DIV
switch. The Horizontal Amplifier contains a variable
magnifier to increase the sweep rate up to at least a
maximum of five times in any position of the SEC/DIV
switch.
The Power Supply and CRT circuits provide all the
voltages necessary for operation of this instrument.
Circuit Operation
In the following description of the electrical operation
and relationship of the circuits in the 212, circuitry
commonly used by TEKTRONIX is only briefly explained.
If more information is desired on the commonly used
circuits, refer to the following textbooks:
Phillip Cutler, "Semiconductor Circuit Analysis",
McGraw-Hill, New York, 1964.
Lloyd P. Hunter (Ed.), "Handbook of Semiconductor
Electronics", second edition, McGraw-Hill, New York,
1962.
Jacob Millman and Herbert Taub, "Pulse, Digital, and
Switching Waveforms", McGraw-Hill, New York, 1965.
6-1
TM 9-6625-646-14&P
Vertical Input Amplifiers
Input signals for vertical deflection of the CRT of the
212 are applied to the tips of the attached probes. Each
Input Amplifier provides control of input coupling, variable
attenuation, vertical deflection factor, balance, and
vertical position (with channel on-OFF) for the
appropriate channel. Figure 6-1 shows a detailed block
diagram of the Vertical Input Amplifier circuit. A
schematic of this circuit is shown on diagram 1.
Input signals applied to the tips of the probes are
connected to the appropriate Attenuation Stage through
the INPUT COUPLING switches (S305 and S405) . The
deflection factor in each channel is determined by the
VOLTS/DIV switch (S310 or S410). In all positions of the
VOLTS/DIV switches below .1 V/DIV, the correct
deflection factor is achieved by changing the gain of
Feedback Amplifiers U320-A and U320-B. In switch
positions .1 V/DIV and up, precision attenuators are used
(in addition to changing the gain of U320-A and U320-B)
to achieve the correct deflection factors. When the
VOLTS/DIV VAR control is rotated, the signal is
attenuated across R320 or R420. This offers variable
(uncalibrated) deflection factors between the calibrated
settings of the VOLTS/DIV switch. The STEP ATTEN
BALance adjustments (R315 and R417) control the tr ace
shift when switching between deflection factors.
The 212 can be operated single trace by turning
either vertical POSition control to the OFF detent; this
disables that channel in the last feedback stage of the
Input Amplifier through the operation of the Vertical
Mode Multivibrator U440. The CH 2 trigger signal is
present regardless of the CH 2 POS control setting. In
the dual-trace mode, the instrument will automatically
chop or alternate, depending upon the sweep rate.

TM 9-6625-646-14&P
Vertical and Horizontal Output Amplifiers
The Vertical and Horizontal Output Amplifiers provide
the final amplification for the deflection signals. Figure 62 shows a detailed block diagram of these Output
Amplifiers. A schematic of these c ircuits is on diagram
2.
Both amplifiers contain the same basic circuitry. The
single-ended input signals are applied to paraphase
amplifiers, U105-A and U105-B, to convert the signal into
push-pull output signals. The Vertical Paraphase
Amplifier stage contains the VERT GAIN adjustment
(R470) that sets the over-all gain of the ver tical system,
and a Vertical Centering adjustment (R101) to set DC
centering. The Horizontal Paraphase Amplifier stage
contains the HORIZ GAIN adjustment (R475), the
HORIZ MAG control (R476), and the Horizontal POSition
control (R480). The output signals from the Paraphase
Amplifiers receive final amplification in the c ommon bas e
Output Amplifier stages.
Figure 6-2. Vertical and Horizontal output amplifiers detailed block diagram.
6-3
TM 9-6625-646-14&P
Trigger/Sweep Generator
Integrated circuit U370 is a combination
Trigger/Sweep Generator. The Trigger portion derives
trigger signals internally, either from the capacitively
coupled CH 2 Vertical Input Amplifier, or from the direc tly
coupled COMPosite signal from the input of the Vertic al
Output Amplifier. The Trigger portion can also select
signals from an external signal applied to the EXT TRIG
banana jack. Controls are provided in this circuit to
select trigger level, slope, and source. Figure 6- 3 shows
a detailed block diagram of the Tr igger/Sweep G enerator
circuit. A schematic of this circuit is on diagram 2.
The Sweep Generator portion of U370 serves a
multiple purpose. In all positions of the SEC/DIV switch
except X-Y, the Sweep Generator is an integrator, which
generates a linear sawtooth voltage waveform. The
slope of the sawtooth voltage is controlled by the setting
of the SEC/DIV switch. U370 also produces an
unblanking gate signal coincident with the sawtooth
waveform. This gate signal is amplified by Unblanking
Amplifier Q134 and applied to the CRT to unblank the
CRT during sweep presentation. In addition, the Sweep
Generator supplies the clock pulses to the Vertical Mode
Multivibrator for alternate switching between channels.
In the X-Y position, the Sweep Generator section
becomes a feedback amplifier to amplify the signal
applied to the probe tip of CH 1.

TM 9-6625-646-14&P
Power Supply
The Power Supply provides the power necessary to
operate this instrument or, if the instrument is turned off,
to recharge the batteries. Figure 6-4 shows a detailed
block diagram of this circuit. A schematic of this circuit is
shown on diagram 4.
When the instrument is connected to a power line the
AC power is capacitively coupled to the Power Rectifier.
The rectified DC is used to either run the instrument or
recharge the internal batteries. The batteries act as a
large filter capacitor for the Input Rectifier in the AC line
mode of TM 9-6625-646-14&P operation. When the
instrument is not connected to a power line, operating
power is provided by the batteries. The POWER
(BATTERY) indicator, light emitting diode DS310, is
illuminated when the 212 is operating from line voltage or
adequately charged batteries. When about 10 minutes
of operating time remains, the battery charge drops to a
point where DS310 will extinguish. The Discharge
Protection circuit (0231, Q235) prevents the Converter
Multivibrator (Q242, Q249) from func tioning, and thereby
overdischarging the ’batteries, when the charge level of
the batteries falls below approximately 10 volts. The
Converter Multivibrator changes DC into AC, which is
applied across T250 and then rectified into the
appropriate DC voltages in the Rectifier circuit.

CRT Circuit
The CRT circuit provides the high voltage and contr ol
circuits necessary for oper ation of the cathode-ray tube
(CRT). Figure 6-5 shows a detailed block diagram of the
CRT circuit. A schematic of this circuit is given on
diagram 3.
Rectifiers CR261 through CR268 provide the negative
accelerating potential for the CRT. Voltage output is
approximately -1000 volts at the CRT cathode. Filament
voltage for the CRT is provided by a spearate winding of
the power transformer. Display intensity and focus are
controlled by R395 and R398 respectively. The Trace
Rotation adjustment controls the current through L300
and affects both the vertical and horizontal alignment of
the CRT beam.

CORRECTIVE MAINTENANCE
TM 9-6625-646-14&P
Obtaining Replacement Parts
Standard Parts. All electrical and mechanical part
replacements for the 212 c an be obtained through your
local TEKTRON IX Field Office or representative.
However, many of the standard electronic components
can be obtained locally in less time than is required to
order them from Tektronix, Inc. Before purchasing or
ordering replacement parts, c hec k the parts list for value,
tolerance, rating, and description.
NOTE
When selecting replacement parts, it
is important to remember that the
physical size and shape of a
component may affect its
performance in the instrument. All
replacement parts should be direct
replacements unless it is known that
a different component will not
adversely affect the instruments
performance.
Special Parts. In addition to the standard electronic
components, som e special components are used in the
212. These components ar e manufactured or selected
by Tektronix, Inc., to meet specific performance
requirements, or are m anufactured for Tektronix, Inc . in
accordance with our specifications. Most of the
mechanical parts used in this instrument have been
manufactured by Tektr onix, Inc . O rder all s pecial parts
directly from your local TEKTRONIX Field Office or
representative.
Ordering Parts. When ordering replacement
parts from Tektronix, Inc., include the following
information:
1. Instrument type.
2. Instrument serial number.
3. A description of the part (if electrical, include
circuit number).
4. TEKTRONIX Part Number.
Circuit Board Replacement. If a circuit board is
damaged beyond repair, the entire assembly including all
soldered-on components can be replaced. Part numbers
are given in the Mechanical Parts List f or the com pletely
wired board.
Semiconductor Replacement. Semiconductors
should not be replaced unless actually defective. If
removed from their sockets during routine m aintenance,
return them to their original sockets. Unnecessary
replacement of semiconductors may affect the
calibration of the instrument. W hen semiconduc tors are
replaced, check the operation of that part of the
instrument which may be affected.
Replacement semiconductors should be of the
original type or a direct replacement. Figure 5-2 shows
the lead configurations of the semiconductors used in
this instrument. Som e plastic case transistors have lead
configurations which do not agree with those shown
here. If a replacement transistor is made by a
manufacturer other than that of the or iginal, c heck the
replacement manufacturer’s basing diagram for correct
basing. All transistor sock ets in the 212 are wired for the
basing used for metal-cased transistors.
When re-inserting an integrated circuit, key the
socket’s index with that of the integrated circuit’s. Failure
to do so can result in damaged components.
Power Supply Capacitors. When operating the
Instrument on power lines other than 115 VAC 60 Hz, It
is necessary to change the electrical value of four
capacitors (C204, C215, C210, and C212) in the
instruments power input circuitry. Refer to Table 7-1 f or
the correct values of capacitance for three of the more
commonly used line voltage/line frequency combinations.

If the instrument is to be operated on some line
voltage/line frequency combination other than one of the
above three examples, refer to Fig. 7-1 and Fig. 7-2 to
select the correct values of capacitance for C210 and
C212. For example, if the instrument is to be oper ated
on a 60 hertz line that will vary in voltage from 210 VAC
to 230 VAC, refer to Fig. 7-2. Trace across the graph on
the line representing 210 VAC to the point where that line
crosses the first curve. This point represents the
minimum values of capacitance that can be used for
correct operation. Now trace across the graph on the
line representing 230 VAC to the point where that line
crosses the second curve. This point represents the
maximum values of capacitance that can be used for
correct operation. Read off the numbers dir ectly under
these points at the bottom of the graph to find the value
of capacitance required for C210. Read off the number s
directly above these points for the value of capacitance
required for C212. Thus, C210 can be a value between
µf and 0.92 µf and C212 can be a value between
0.75
µf and 1.87 µf. The voltage ratings of these
1.54
capacitors should be at least 1.414 times the RMS value
of the applied line voltage.

TM 9-6625-646-14&P
When replacing C210 and C212, be certain the foam
pad is under the replacement capacitor.
Rotary Switches. Individual parts of the VOLTS/DIV
and SEC/DIV rotary switches are replaceable. Refer to
the Parts List for the applicable part numbers for
replacement parts.
Selectable Components. Resistor R388 value is
selected for a switching unblanked trace height of no
more than 1.5 divisions for each channel and minimum
intensity change when changing sweep speed from 5 ms
to 2 ms. The value of R388 is selected from a range of
270, 300, or 330 ohms as follows:
1. Install a 270 ohm resistor for R388, turn the
212 on, set SEC/DIV to .5 s, and set INTENSITY to
maximum (fully clockwise).
2.The traces will show as dots. Set CH 1 POS to
place the CH 1 dot to the top horizontal graticule line and
set CH 2 POS to place the CH 2 dot to the bottom
horiztontal graticule line.
3.Check that no more than 1.5 divisions of
unblanked trace extends vertically from each dot.
4.If each unblanked trace exceeds 1.5 vertical
divisions, turn off the 212, install the next larger size for
R388, recheck and repeat steps 2 through 4 until
unblanked traces are no more than 1.5 divisions high
while maintaining minimum intensity change when
switching sweep speed from 5 ms to 2 ms.

a
.This section provides a general explanation of all maintenance and repair functions authorized at various
maintenance categories.
b
.The Maintenance Allocation Chart (MAC) in Section II designates overall authority and responsibility for the
performance of maintenance functions on the identified end item or component. The application of the maintenance
functions to the end item or component will be consistent with the capacities and capabilities of the designated
maintenance categories.
c
.Section III lists the tools and test equipment (both special and common) r equired for each maintenance function
as referenced from Section II.
d
.Section IV contains supplemental instructions and explanatory notes for a particular maintenance function.
