GENERAL INFORMATION
INTRODUCTION
The TEKTRONIX 2230 Oscilloscope
is
a combination
nonstorage
and
digital storage dual-channel 100 MHz
bandwidth instrument. It
is
a rugged, lightweight oscillo-
scope featuring microprocessor operation
and
alphanumeric crt readout of many of the front-panel con-
trols.
In
the digital storage mode, up to three waveform
sets
(CH
1 and/or
CH
2)
may
be
stored
in
a SAVE
REF
memory
and
recalled for display at a later time. The verti-
cal system provides calibrated deflection factors from
2 mV per division to 5 V per division. The horizontal sys-
tem provides calibrated sweep speeds from 50
ns
per divi-
sion to 0.5 s per division for nonstorage mode with three
slower sweep speeds
(1
s,
2
s,
and
5 s per division) added
for store mode operation. A X10 magnifier extends the
maximum sweep speed to 5 ns per division.
The digital storage sampling rate
is
20
megasamples
per second maximum,
and
the acquired record length
is
4K samples
(1
K may also
be
selected) for a single channel
or
2K samples for dual-channel (CHOP or ALT) displays.
Any contiguous 1 K sample of
an
acquired record
is
displayable. The fast sampling rate
can
capture a glitch
with a pulse width of at least 100 ns. A 4K compress
feature enables a 4K record length acquisition to
be
compressed
to
1 K
in
length for ease
in
viewing or storing
in
the SAVE
REF
memory. If compression
is
not desired,
all 4K
or
any 1 K portion of a 4K record may
be
stored
in
the SAVE
REF
memory. The SAVE store mode stops the
waveform acquisition
in
progress, allowing a particular
display
to
be
stored or examined before further acquisi-
tions cause a waveform update.
Cursors may
be
used to obtain voltage measurements,
time difference measurements,
and
delay-time measure-
ments on any of the store mode waveform displays. Delta
volts, delay time, delta time,
and
1/delta time (either delta
time or 1/delta time
is
selectable via the MENU) are
displayed
in
the crt readout for ease
in
obtaining precise
measurement results. The cursors are positioned to any
displayed store mode waveform to make measurements.
An alternate use of the cursor-positioning control
is
to hor-
izontally position the 1 K display window to any location
within a
4K
record length waveform acquisition. The
displayed portion
of
a 4K acquisition
is
stored when the
SAVE REF feature
is
used.

SPECIFICATION
The following electrical characteristics (Table 1-1)
are
valid when the instrument has
been
adjusted at
an
ambient temperature between
+20°C
and
+30°C,
has
had a warm-up period of at least
20
minutes, and
is
operating at
an
ambient temperature between
0°C
and
+50°C
(unless otherwise noted).
Items listed
in
the "Performance Requirements" column
are verifiable qualitative or quantitative limits that define
the measurement capabilities of the instrument.
Environmental characteristics are given
in
Table 1-2.
This instrument meets the requirements of MIL-T-28800C
for Type Ill, Class 5 equipment, except where noted other-
wise.
Physical characteristics of the instrument are listed
in
Table 1-3.
