Before
operating
this
instrument,
be
sure
to
remove
the
plastic
shipping
clamps
from
the
shock
mounts
of
the
amplifier
chassis.
These
clamps
should
be
saved
and
reinstalled
as
shown
in
the
sketch
if
the
instrument
is
to
be
shipped.
Be
sure
the
tongue
is
inserted
next
to
the
chassis
to
prevent
damage
to
the
shack

The
clamp
should
be
on
the

of
the

as
the
nut.

General
Information
The
Tektronix
Type
519
Oscilloscope
is
a
wide-band
laboratory
instrument
designed
expressly
for
the
observation
and
measurement
of
high-frequency
phenomena.
Fast
linear
sweeps,
high
CRT
accelerating
potential,
excellent
triggering
sensitivity,
wide-band
trigger
system,
and
vertical
bandwidth
well
beyond
1000
megacycles
permit
accurate
repetitive
and
single-shot
displays
to
be
observed
and
photographed
from
tractional-nanosecond
signals.
An
inter-
nal
delay
line
in
the
vertical
channel
of
the
instrument
permits
display
of
the
leading
edge
of
the
signal
triggering
the
oscilloscope.
Sweep
delay
control
through
35
nano-
seconds
permits
viewing
signals
before
and
after
the
main
signal
event.
The
Type
519
incorporates
two
internal
waveform
gen-
erators.
An
adjustable
repetition-rate
fast-rise
pulse
gen-
erator
and
a_
fast-rise
calibration-step
generator
supply
waveforms
which
can
be
used
to
check
the
calibration
of
the
oscilloscope
itself,
or
to
drive
external
devices.
These
wave-
form
generators
meet
most
requirements
to
complete
a
test
setup.

Introduction
>
The
Type
519
Oscilloscope
is
a
high
speed
laboratory
instrument
designed
for
observing,
measuring,
and
photo-
graphically
recording
phenomena
in
the
nanosecond
{milli-
microsecond)
domain.
However,
before
the
instrument
can
be
used
successfully,
it
is
important
for
you
to
have
an
un-
derstanding
of
the
operation
of
each
control.
This
section
of
the
Instruction
Manual
is
intended
to
help
you
acquire
this
understanding.
Much
of
the
familiarity
with
the
controls
will
come
only
with
actual
use
of
the
instrument.
A
brief
description
of
each
of
the
front-panel
controls
follows.
Front-
panel
markings
are
shown
in
Fig.
2-1.
FUNCTION OF CONTROLS
CRT
FOCUS Used in conjuction with the ASTIGMATISM
control to focus the oscilloscope trace.
INTENSITY Adjusts the brightness of the trace.
ASTIGMATISM — Used in conjunction with the FOCUS con-
trol to obtain a round spot and a sharply
focused trace.
SCALE ILLUM. = Adjusts the brightness of the graticule
markings.
Graticule A knurled knob located below the center
Control of the graticule permits graticule to be
moved down out of the viewing area.
TIME BASE
NANOSEC/CM | Selects the desired time base.
DELAY Determines the delay of the start of the
sweep with respect to the trigger signal
input.
NORMAL-SINGLE Selects either normal or single-sweep
SWEEP operation.
RATE GENERATOR
CYCLES/SEC Used in conjunction with the MULTIPLIER
control to set the Rate Generator out-
put frequency.

Generator is not being used.
CALIBRATION-STEP GENERATOR
RANGE
Selects
full-scale
amplitude
of
the
cali-
brated
steps,
a
variable
uncalibrated
step
amplitude,
or a
standby
condition.
Should
be set
to
STANDBY
when
Calibration-Step
Generator
is
not being
used.
VARIABLE
Permits
the
step
waveform
to
be
preset
to
an arbitrary
desired
amplitude
up
to about
50
volts
into
a 125-ohm
load.
VOLTS
Sets
the
output
voltage
of
the
calibration-
step
waveform
in
the 10V
and
1 V
posi-
tions
of
the RANGE
switch.
REED SWITCH:
DRIVE
Adjusts
the
reed-switch
magnetic
excita-
tion
for
proper
closures
or
permits
single
reed
operation.
FREQUENCY
Controls
frequency
of
the
reed-switch
mag-
netic
excitation
to
help
minimize
contact
bounce.
