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 is set
to 0.05 µs
per
division.
The instrument is shipped
with
the following standard
