SECTION

CHARACTERISTICS
General
The
Tektronix
Type
585
Oscilloscope
is
a
wide
range,
general
purpose
laboratory
instrument
which
provides
accurate
measurements
in
the
d
c
to
approximately
95
mega
cycle
range.
Plug-in
amplifiers
are
used
in
the
vertical
de
flection
system,
permitting
the
instrument
to
be
used
in
many
specialized
applications.
Any
of
the
Tektronix
Eighty
Series
Plug-In
Units
can
be
used
with
the
oscilloscope
to
satisfy
many
types
of
wide-band
uses.
Use
of
the
Type
81
Plug-In
Adapter
permits
use
of
any
of
the
Tektronix
letter
series
plug-ins
for
applications
involving,
among
others,
dual
trace
operation,
low
level
signals,
differential
signals,
pulse
sampling,
and
transistor
risetime
checking.
High
calibrated
sweep
rates
allow
full
use
of
the
rise-time
capabilities
of
the
instrument.
Special
circuits
incorporated
in
the
Type
585
Oscilloscope
allow
accurate,
continuously
variable
delay
in
the
pre
sentation
of
a
sweep
from
1
microsecond
to
10
seconds
after
the
receipt
of
a
triggering
impulse.
The
delayed
sweep
feature
permits
highly
magnified
displays
of
a
small
portion
of
an
undelayed
sweep;
accurate
measurements
of
wave
form
time
jitter;
precise
time
measurements,
as
well
as
many
other
uses.
VERTICAL
DEFLECTION
SYSTEM
Characteristics
for
the
vertical
deflection
system
of
the
Type
585
Oscilloscope
depend
upon
the
plug-in
unit
and
probe
used
with
the
instrument.
