GRATICULE MOUNTING PROBLEMS
Tom Smith, Field Engineer with our Phil-
adelphia Field Office, iniorms us that some
of his customers have a prolilem. They arc
confused about the proper sequence for the
installation of components over the face of
crt's in Tektronix oscilloscopes.
\\"e offer the following information in an
effort to cle;tr up some of this confusion.
Except ior some instruments (which we
will designate later), the light
filter
is
shippe<L unmounted and as an accessory to
the oscilloscope.
\Ve ship all oscilloscopes employing a 5"
-crt
with
a
black
plastic
(Royal-lite)
light shield installed. This shield has a 5"
opening with a
Yi"
flange at right angle to
the opening.
The face of the shield is
slightly smaller than the graticule cover
and contains seven holes.
The edge with
the
four holes is the lop.
This shield is
installed by inserting the flanged portion
between the crt and the surrounding mu-
metal shield.
Properly installed, the light
shield
fits
flush
against
the
instrument
panel. The four holes in each corner allow
the graticule studs to protrude.
The two inner holes at the top permit the
graticule lights to show through the light
shield.
The seventh hole, located in the
lower left-hand corner and just aho\"e the
graticule stud, permit;; access to the cam-
adjust fitting on instruments containing the
cam-adjust feature.
Over this light shield, we install the grati-
cule making sure the etched-line side faces
to the crt.
The red-rimmed holes in the
graticule are positioned at the top ancl sur-
round the graticule lights.
On each graticule stud,
\\·e
install a rub-
ber washer. The graticule cover then goes
over the whole assembly and the graticulc-
stud nuts hold all firmly in place.
\\"hen
installing the graticule cover,
make sure
the small hole in the circular flange of the
co\"er i;; at the top.
Placement in this
position permits correct attachment of the
Tektronix
Viewing
Hood
with
molded-
rubber eyepiece (Tek No. 016-001) or the
Tektronix
Polarized
Viewer
(Tek
No.
016-035).
Instruments shipped with the green light
filter installed are; Type 524
AD
Television
Oscilloscope, Type 525 Television \\·a,·eform
Monito1-, Type 526 Color-Television Vector-
scope, Type 527 \\';weform Monitor, Type
575 Tr;msistor-Curvc Tracer, and all in-
struments ordered with a P-1 phosphor crt.
Installation of components around and
over the iace of the crt in these inst rumen ts
cliff crs from the foregoing inst ructions in
onlv two respects: (l) \\'e install the green
ligl;t filter between the hlack light shield
and the gratirnle.
(2) \\'e do not use the
four rubl1er washers between the graticule
and the graticule cover.
On oscilloscopes employing 3" crt's we do
not install a light shield. The light filter is
shipped unmounted as an accessory (unless
the oscilloscope is ordered with
a
P-1 phos-
phor). Three-inch oscilloscopes do not have
the cam-adjust feature.
In all other ways,
installation of
components
over
the
crt
follow the fo1·egoing instructions for
5"
oscilloscopes.
\ \! e place the etched side of the gralicules
whenever possible next to the face of the
crt.
This avoids 11arallax and thus errors
in reading oscilloscope measurements.
There is little to be gained by placing the
light filler over the graticule. The graticule
lines will not show through the filter suf-
ficiently enough to he useable.
Should you prefer white graticule lines
(such as when taking pictures of oscillo-
scope traces) you may, on the 5" oscillo-
scopes only, rotate the graticule 180°. Re-
member keep the etched side next to the
face of the crt.
