independent amplifier channels with identical characteristics,
and features solid-state circuitry and simplicity of
operation.

with or without a probe. Any channel may be used to
produce a single-channel display. All channels may be displayed alternately, or channel 4 and 3 may be alternated
with 2 and 1 to produce four displayed channels. While
designed primarily for use as a vertical amplifier, the unit can
be operated in conjunction with the horizontal deflection
system of the oscilloscope for X-Y displays.

GENERAL INFORMATION
Applying Signals
When measuring DC voltage, use the largest deflection
factor (5 V/Div) when first connecting the 5A14N to an un-
known voHage source. H Ihe deflection is loo small to make
the measurement, switch to a smaller deflection factor.
In general probes offer the most convenient method of
connecting a signal lo the input of the 5A14N. Tektronix
probes are shielded to prevent pickup of electrostatic
interference. A 10X attenuator probe oilers a high input
impedance and allows the circuit under test to perform very
close to normal operating conditions. The 5A14N is de-
signed for compatibility with coded probes,. The input
connector has an outer ring to which the coding ring on the
probe connector makes contact. This type of probe allows
the vertical deflection factor indicated by the readout to
correspond with the actual deflection factor at the probe tip,
eliminating the need to consider the attenuation factor of
the probe when measuring the signal amplitude on the
graticule scale. See your Tektronix, Inc., catalog lor
characteristics and compatibility of probes for use with this
system.
Sometimes unshielded test leads can be used to connect
the 5A14N to a signal source, particularly when a high-level,
low-frequency signal is monitored at a low-impedance
point. However, when any of these factors is missing, it
becomes increasingly important to use shielded signal
cables. In all cases, the signal transporting leads should be
kept as short as practical. Be sure to establish a common
ground connec:tion between the device under test and the
5A14N.

larger than the AC component, AC coupling (button in) will
probably provide a better display. DC coupling should be
used to display AC signals below atout 2 hertz as they will
be attenuated in the AC position.
In the AC position, the DC component is blocked by a capacitor in the input circuit. The low-frequency response in
the AC position is about 2 hertz (-3 dB point). Therefore,
some low-frequency attenuation can be expected near this
frequency limit. Distortion will also appear in square waves
which have low-frequency components.

Deflection Factor
The amount of trace deflectbn produced by a signal is determined by the signal amplitude, the attenuation factor (if
any) of the probe, the setting of the VOLTS/DIV switch,
and the setting of the Variable control. The deflection factors indicated by the VOLTS/DIV switch are calibrated only
when the CAL control is rotated fully clockwise to the detent position.
The range of the CAL control is at least
uncalibrated deflection factors covering the full range between the fixed settings of the VOLTS/DIV switch. The
control can be set to extend the deflection factor to at least
12.5 volts/division.

THEORY OF OPERATION
5A14N
INTRODUCTION
This section contains an electrical description of the circuits
in the 5A14N Four Channel Amplifier unit. A complete
block and schematic diagram is given on a pullout page at
the back of the manual.
The four channels are nearly identical except for Trigger
Pickoff, which occurs in Channel 1 only. Thus, this discussion concerns only Channel 1 except for the Channel
Switching portion, which necessarily involves all the chan-
nels.
PLUG-IN LOGIC
When the DISPLAY button, S510, is pressed, a logic level
is applied to the electronic switching circuit in the oscilloscope to enable plug-in operation (this button has no effect
when the plug-in is inserted in a horizontal plug-in
compartment). Power is applied to illuminate the frontpanel knob-skirt readout lamps, indicating the ON mcxJe.
INPUT COUPLING
Signals applied to the front-panel input connectors may be
capacitive coupled (AC), direct coupled (DC), or internally
disconnected (GND). Provision is made to precharge (or
discharge) the input capacitor to protect delicate circuitry
under test. When both the AC and GND buttons are
pressed,
input capacitor is pre-charged through a one-megohm
resistor to the level of the applied input signal.
the input to the amplifier is grounded and the
AMPLIFIER
The Input amplifier consists of two identical feedback
amplifiers, connected in a paraphrase configuration.
Quiescently, the two sides of the amplifier are balanced by
the internal Step Atten Bal adjustment Rl 15 so there is no
current through the gain-setting resistor (R123 through
R128). See Figure 2-1. An input signal is developed
across the gain-setting resistor, shifting the current

INPUT ATTENUATOR
The deflection factor of the plug-in is set by a combination
of gain switching in the amplifier and input attenuatbn.
The input attenuator is a frequency-compensated voltage
divider that provides 100X attenuation in the 0.1 V to 5 V
positions of the VOLTS/DIV switch. At DC and for tow-frequency signals, the divider is essentially resistive
(attenuation ratio determined by the resistance ratio of
R107 and R108). At higher frequencies, the capacitive
reactance becomes effective and the attenuation ratio is
determined by the impedance ratio.
In addition to providing constant 10OX attenuation, the input attenuator maintains a constant input RC characteristic
(one megohm paralleled by about 47 pF) for 0.1 V to 5 V
settings of the VOLTS/DIV switch.

Q134 and Q138 by the amount established through R123R128,
and developing a push-pull output signal across
R134 and R138. The gain of this amplifier ranges from
about one to fifty, and is primarily determined by the ratio of
the gain-setting resistor to the sum of R134 and R138.
The push-pull signal voltage from 0134 and 0138 collectors then passes through emitter followers 0142 and Q146
and is transformed to a signal current by 0160 and 0162.
The Variable VOLTS/DIV (CAL) potentiometer R168, and
the Gain-setting potentiometer R166, reduce the gain in
the Q160-Q162 stage by developing an adjustable amount
of signal voltage between their emitters.
Q150,
0156 and 0158 in Channel 1 only receive the pushpull signal and provide a single-ended trigger signal out.
0177 and Q178 provide positioning current.
CHANNEL SWITCHING
When only the CH 1 DISPLAY button S510 is pressed,
0510 is biased off, turning on Channel 1 switches 0180
and 0182 and albwing a signal to pass.
When only the CH 2 DISPLAY button S520 is pressed,
Q510 is biased on, switching Q516 off. This action turns
Channel 2 switches Q280 and 0282 on.
When both CH 1 and CH 2 buttons are pressed (dual-trace
mode), the state of O510 and 0516 is determined by the
channel-switching signal generated in the oscilloscope
mainframe. The form of this signal is selected on the sweep
plug-in by the Alternate-Chop Mode button.
Channels 3 and 4 operate as a switched pair just as Channels 1 and 2. Thus, the Channel 3 switches Q380 and
0382 are controlled by Q520, and the Channel 4 switches
Q480 and 0482 are controlled by Q526. When both
Channels 3 and 4 are ON, they are either alternated or
chopped as a pair through Q520 and 0526 by the channelswitching signal.
Channels 1 and 2 are displayed as a composite pair when
their composite switches Q530 and 0534 are turned on.
This occurs when Q550 is biased off. Channels 3 and 4
composite switches Q540 and 0544 are similariy turned on
when 0556 is biased off. When one or two channels from
each composite pair are ON, U550 switches between the
two pairs at either 1/2 or 1/4 the Alternate or Chop rate of
the channel-switching signal. U550 divides the channel-
switching signal by 2 in the Dual Beam position or by 4 in
the Single Beam position of S550. The divided channel-
switching signal from S550 determines the state of Q550
and Q556 when 1 or 2 channels from each composite pair
are
ON.
PROBE SENSING
Either of two lamps located behind the VOLTS/ DIV knob
skirt illuminates the selected deflection factor to provide a
direct readout. Normally, DS190 is lit; connection of a
readout-coded 10X probe extinguishes DS190 and lights
DS196. This changes the knob skirt readout by a factor of
10 to reflect the probe attenuation, eliminating possible
operator error.

PROCEDURE
Calibration—5A14N
1.
Step Attenuator Balance
Preparation
1.
Remove the protective cover from the left side of the
5A14N and also the left side panel from the 5000series oscilloscope. (The plug-in extender can be
used to gain access to the internal adjustments rather
than by removing the oscilloscope side panel.) Insert
the 5A14N into the left plug-in compartment, and the
5B10N into the right compartment.
2.
Connect the oscilloscope to the power source for
which it is wired. Set the controls as described under
Initial Control Settings. Refer to Figure 3-1 for location of internal adjustments and test points.
NOTE
This instrument should be calibrated at an ambient temperature between +20° C and
(+68° F and -^86° F) for best accuracy.
-1-30°
C
Initial Control Settings
NOTE
Do not preset internal controls unless they are
known to be significantly out of adjustment, or
unless repairs have been made in the circuit. In
these instances, the internal control scan be
set to midrange.
5A14N (All Channels)
a. Position the CH 1 trace to graticule center and adjust
R115 (CH 1 STEP ATTEN BAL) for no trace shift
when the VOLTS/DIV switch is turned throughout its
range.
b. Turn the CH 1 CAL control throughout its range and
check for less than 1 division of trace shift. Return
the CAL control to the fully cw (detent) position.
c. Repeat the preceding procedure for CH 2 through
CH 4. Adjust R215, R315, and R415 respectively.
2.
Input and Attenuator Compensation
a. Set all VOLTS/DIV switches to 0.1. Apply a 1 volt
signal from the Standard Amplitude Calibrator, using
the HIGH AMPL mode, through the Input RC
Normalizer to the 5A14N CH 1 input. Adjust the time
base triggering Level control for a stable display.
b. Adjust Cl
for a square leading corner on the square-wave display.
c. Set CH 1 VOLTS/DIV to 50 m and the Standard Am-
plitude Calibrator for a 0.5 volt output. Adjust C106
(ATT 2) for a square leading corner on the display.
d.
Set CH 1 VOLTS/DIV to 0.1 and the Standard Am-
plitude Calibrator for a 1 volt output. Adjust C107
(ATT 3) for a square leading corner on the display.
e. Repeat the preceding procedure for the remaining
channels. Adjust the attenuator capacitors that correspond to those adjusted in channel 1.

wave output and adjust the time-base triggering
Level control for a stable display.
c. Adjust R166 (CH 1 GAIN) for exacfly 5 divisions of
display.
d.
Repeat the preceding procedure for CH 2 through
CH 4. Adjust R266, R366, and R466 respectively.
e. Set all VOLTS/DIV switches to 5 and connect the

MANUAL CHANGE INFORMATION
At Tektronix, we continually strive to keep up with latest electronic developments
by adding circuit and component improvements to our instruments as soon as they
are developed and tested.
Sometimes, due to printing and shipping requirements, we can't get these
changes immediately into printed manuals. Hence, your manual may contain new
change Information on following pages.
A single change may affect several sections. Since the change information sheets
are carried in the manual until all changes are permanently entered, some
duplication may occur. If no such change pages appear following this page, your
manual is correct as printed.
