SPECIFICATION
INTRODUCTION
The TEKTRONIX 2246 Oscilloscope is a portable
100
MHz
bandwidth
instrument
having
a
four-channel
vert-
ical deflection system. The horizontal deflection system
provides calibrated sweep speeds from 0.5 to 20 ns per
division and delayed sweep features. The trigger system
provides stable triggering over the full bandwidth of the
vertical
deflection
system.
Alphanumeric
crt
readouts
of
the vertical and horizontal scale factors are displayed at
the bottom of the screen. On-screen vertical and horizontal
cursors provide accurate voltage, time, frequency, and
phase
measurements
with
measurement
value
readouts
displayed at the top of the crt.
The
2246
is
microprocessor
controlled
and
features
menu-driven
waveform
measurement
processes.
The
flexi-
bie
measurement
features
of
the
oscilloscope
include
a
choice
of
either
voltmeter
measurements
for
-+
Peak,
—
Peak,
Peak-to-Peak,
and
average
DC
values
of
the
sig-
nal
applied
to
a
selected
measurement
channel
or
position-
able
cursors
for
measuring
voltage
difference,
time
difference,
frequency
and
phase.
Measurement-tracking,
trigger-level
tracking,
and
ground-tracking
SmartCursors
®
that
provide
visual
feedback
to
the
user
may
be
placed
on
the
displayed
waveforms.
Menus
called
up
to
make
the
measurement
mode
choices
are
displayed
at
the
right
side
of
the
crt
next
to
the
menu
selection
buttons.
Delay-time
and
delta-delay
measurements
for
time,
frequency,
and
phase
are
available
in
ALT
and
B
Horizontal
Modes.
The
vertical
deflection
system
consists
of
two
channels
with
calibrated
deflection
factors
from
2
mV
to
5V
per
division
in
a
1-2-5
sequence
of
11
steps
and
two
channels
with
two
basic
deflection
factors
of
0.1
V
and
0.5
V.
Use
of
coded
probes
having
attenuation
factors
of
1X,
10X,
and
100X
extends
the
minimum
sensitivity
to
500
V
per
division.
VOLTS/DIV
readouts
are
switched
to
display
the
correct
vertical
scale
factor
when
properly
coded
probes
are
attached
to
the
vertical
input
connectors.

or,
if
used
infrequently,
once
each
year.
Replacement
of
com-
ponents
in
the
instrument
may
also
necessitate
