GENERAL INFORMATION
INTRODUCTION
The TEKTRONIX 221 SA Oscilloscope is a rugged, light-
weight, dual-channel 60-MHz instrument that features a
bright, sharply defined trace on an 80-by 100-mm cathode-
ray tube (crt). Its vertical system supplies calibrated deflec-
tion factors from 2 mV per division
to 5 V per divi-
sion.Trigger circuits enable stable triggering over the full
bandwidth
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 magnifier circuit extends the maximum sweep speed
to 5 ns per division when the A and B SEC/DIV switch isset
to 0.05 µs per division.
The instrument is shipped with the following standard
accessories:

FIRST-TIME START UP
SAFETY
Refer to the "Operators Safety Summary" at the front of
this manual for power source, grounding, and other safety
considerations pertaining to the use of the 2215A. Before
connecting the instrument
to a power source, carefully read
the following about line voltages, power cords, and fuses.
LINE VOLTAGE
The instrument is capable of continuous operation using
input voltages that range from
90 V to 250 V nominal at
frequencies from 48 Hz to 440 Hz.
POWER CORD
A detachable three-wire powercord with a three-contact
plug is provided with each instrument
to permit connection
to both the power source and protective grou
nd. The plug
protective-ground contact connects (through the protective-
ground conductor)
to the accessible metal parts of the in-
strument. For electrical-shock protection, insert this plug
only into a power outlet that has a securely grounded pro-
tective-ground contact.
This instrument is shipped with the required power cord
as ordered by the customer. Available power-cord informa-
tion are illustrated in Figure 2

VERTICAL
Refer to Figure 2-4 for location of items 9 through 17.
9 CH 1 VOLTS/DIV and CH 2 VOLTS/DIV Switches-
Used to select the vertical deflection factor in a 1-2-5
sequence.
To obtain a calibrated deflection factor, the
VOLTS/DIV variable control must be in the calibrated
(CAL) detent (fully clockwise).
1X-l ndicates the deflection factor selected when us-
ing either a 1X probe or a coaxial cable.
10X PROBE-I ndicates the deflection factor selected
when using a 1
OX probe.
10VOLTS/DIV Variable Controls-When rotated coun-
terclockwise out
of their calibrated detent positions,
these controls provide continuously variable,
uncalibrated deflection factors between the calibrated
settings
of the VOLTS/DIV switches.
11POSITION Control s-Used to vertically position the
display
on the crt. When the SEC/DIV sw itch is set to
X-Y, the Channel 2 POSITION control moves the dis-
play vertically (Y-axis), and the Horizontal POSITION
con
tr ol moves the display horizontally (X-axis).

12Input Coupling (AC-GND-DC) Switche s- Three-po-
sition
sw itches that select the method of coupling the
input signals
to the instrument deflection system.
AC-Inpu t signal iscapacitively coupled to thever-
tical amplifier. The de component
of the input sig-
nal isblocked. Low-frequency limit (- 3
dB point) is
approximately 10 Hz.
GND- The in put of the vertical amplifier is
grounded
to providea zero(ground) reference-volt-
age display (does notground the input signal). This
switch position allows precharging the input cou-
pling capacitor.
DC -All frequency components of the input signal
are coupled
to the vertical deflection systems.
13 CH 1 OR X and CH 2 OR Y Input Connectors-
Provide for application of external signals to the verti-
cal deflection system
or for an X-Y display. In the X-Y
mode (SEC/DIV switch set
to X- Y), the signal con-
nected
to the CH 1 OR X input connector provides
horizontal deflection
(X-a xis) and the signal connected
to the CH 2 OR Y input connector provides vertical
deflection (Y-axis).
14VERTICAL MODE Switches- Two three-position
switches and one button switch are used
to select the
mode
of operation for the vertical amplifier system.
CH 1- Selects only the Channel 1 input signal for
display.
BOTH
-Selects both Channel 1 and Channel 2 in-
put signals for display. The CH 1-BOTH-CH 2
switch must be in the BOTH position for either
ADD, ALT,
or CHOP operation.
CH 2-Select s only the Channel 2 input signal for
display.
ADD-D isplays the algebraic sum of the Channel 1
and Channel 2 input signal
s.
ALT-Alt ernately displays Channel 1 and Channel
2 input signals. The alternation occurs during re-
trace at the end
of each sweep. This mode isuseful
for viewing both input signals
at sweep speeds
from 0.05
µs per division to 0.2 ms per division.
CH OP- The displ ay switches between the Chan-
nel 1 and Channel 2 input signals during the
sweep. The switching rate is approximately
500 kHz. This mode is useful for view
in g both
Channel 1 and Channel 2 input signals at sweep
speeds from 0.5 ms per division
to 0.5 µs per
division.
