The T202 Oscilloscope

GENERAL INFORMATION
Introduction
The TEKTRONIX
T202 Oscilloscope
is
a
rugged,
lightweight
digital storage
instrument.
The
instru-
ment performs
voltage
,
time
,
and frequency
measurements
on acquired waveforms
.
The
T202
is
a microprocessor
controlled
instrument
and may
be powered either
from Its battery pack or, using
the supplied
adapter
,
from an ac power source.
Waveforms
and measurement results are dis-
played on a Liquid-Crystal
Display
(LCD) with
a
128
x
128
point display
matrix.
The dual-channel vertical
system
has
a 5-MHz
bandwidth with
calibrated deflection factors from
O. 01 volt
per division to
20
volts per division. The
horizontal
system has separate timing circuits for
each
vertical
channel and two time bases with
horizontal
deflection factors from
1
hour per divi-
sion
to 50
nanoseconds per division
.
Second per
division
time base provides the timing speed for
the signal acquisition
and delta
time
base expands
a selected
portion of the second per division time
base to full
display width
.
Acquisition
triggering setups can be automatically
made by the instrument
or
they
may be user se-
lected
for each of the two vertical
input
channels.
A selectable trigger
point permits the user to set
the pretrigger
and post-trigger portions of the ac-
quired waveform.
Specified
points on an acquired waveform for mak-
ing
voltage, time,
frequency, or phase measure-
ments
are user selectable with vertical or horizon-
tal measurement
cursors. Cursor measurement
results are
displayed at the top and bottom of
the
display.
Automatic digital voltmeter and counter
measurement
of the RMS voltage
,
mean
voltage,
peak-to-peak
voltage
,
zero-to-peak voltage
,
pe-
riod, and
frequency of a selected vertical channel
signal is
also available
.
Digital voltmeter and
counter
measurement results are displayed in a
table format.
