DC5090/DC510 MICROPROCESSOR RESET
CYCLER
serial Numbers Affected: All
The following procedure can be
very useful for cycling
microprocessor based instruments
with intermittent kernal problems.
GPIB instruments that support the
•TEST• command may not always
perform a complete power-on self
test.
From time to time it may be
useful to cycle a uP-based
instrument at a rate much
faster than the fifteen
minutes of a typical cycler.
This set-up is a convenient
way of doing it and requires
only a TGS0l (or other clock)
and a DDS0l.
Connect the trigger output of
the TGS0l through a cable,
terminator, and dual input
coupler to the inputs of the
OD501. Connect the output of
the DO501 without a terminator
through a cable and BNC-to-Ez
Hook adapter to the reset pin
of the uP in the instrument
under test.

Set the TGS0l to 1 ms and
trigger the DDS0l. The events
delay count switches will now
control the time between
resets from zero to 99 .999
seconds, in 1 ms increments.

IDD TOUCH-UP PAINT PART NUMBERS:
OLD/NEW COLORS
Approximately 3 years ago, IDD changed
the colors of their products. This has
caused some confusion in determining
which products have the old colors and
which products have the new colors.
The following are three lists, one
listing the IDD products having the Tek
blue color, the second listing the !DD
products having the old gray/tan colors
and the third listing the products
having the new gray/tan colors.
Included with each list of products are
the correct color names and Tek part

Jl6 OPERATING HINTS
REF: Jl6 Manual 070-1879-00
The following article provides some
helpful hints for use of the Jl6.
This infomation can help the
technician achieve more accurate and
repeatable results when adjusting the
color temperature on color picture
monitors.
J16 Photolleter Operating
Reca.endations
Many engineering and manufacturing
areas are using Tek Jl6 photometers
for measuring CRT luminance and
setting color balance of white fields.
I have observed several problems which
seem to reoccur. The following are
some reconnendations regarding the
correct or at least improved
techniques for making these
measurements:
-2-
October, 1883 laeue 31
1) Zerofng--This fs undoubtedly the
greatest single cause of errors with
the Jl6 and can occur with any of the
probes. Due to variations in silicon
input bias current, the zero should
always be rechecked when changing
probes and when the photo-diode
temperature changes. This fs most
noticeable on r.t. powered Jl61s where
the photo-diode is positioned directly
over the r.t, power supply when plugged
into the top of the Jl6. Also when
using the r.t, power supply, continuous
operation or at least 1/2 to 1 hour
wamup is best to minimize zero drift
on the most sensitive ranges.
The Jl6 uses a mono-polar DVM circuit
which will still read 000 even when
the zero is offset in a negative
direction. This has the appearance of
non-linearity especially at low light
levels. Also the same reading will
not be obtained when changing to the
next range. To let the operator know
that it fs incorrectly zeroed, the
minus sign fs wired to indicate that
the zero fs offset in a negative
direction. To correctly zero the Jl6,
cover the sensor and adjust the zero
adjustment on the O.lX range until the
minus sign just flickers on and off.
An alternate aethod fs to adjust the
zero until a reading of typically 5 fn
the last place dfgft fs obtained.
This reading fs checked often when
using the most sensitive ranges. If
the Jl6 zeros correctly on the XO.l
range but fs incorrect on the XlOOO
range, ft fs an fndfcatfon that the
internal DVM zero needs readjustment
according to the procedure fn the
manual.
The zero procedure fs more complex
when using the J6523 1 luminance
probe--enough so that I reconnend use
of the Minolta 1 spot meter, ff
possible, rather than the Jl6/J6523.
The Minolta has auto ranging. no
zeroing required, compact size and a
display that fs visible through the
eyepiece used for sighting. The
(ARTICLE CONTINUED ON THE NEXT PAGE)

Jl6 OPERATING HINTS (CONT.)
trade-off fs a poorer spectral match
to the CIE photopfc response curve.
To correctly zero the J6523/Jl6
combfnatfon, cover the J6523 objective
lens and adjust the J6523 zero on the
XlOOO range. Then change to the XO.l
range and adjust the Jl6 zero. It fs
usually necessary to repeat the
procedure once or twfce as the
adjustments interact. There fs an
incompatabilfty between the J6523 and
very early Jl6's that prevents zeroing
on the XlOOO range. A simple mod kit
fs available to cure ft. The kft P/N
fs 040-0746-00, and applies to the
Jl6's below S/N 8052000.
2) Calf bration--The photopfcally
corrected J16 probes are all initially
calibrated fn the plant usfng 3000 K
tungsten-halogen white light source.
For maximum accuracy with CRT's they
should be calibrated for the
individual phosphors to be measured.
Correction factors up to approximately
101 (higher for the Mfnoltas) may be
necessary to obtain correct data due
to devfatfons from the photopic
response curve. Thfs fs most severe
in the red and blue regions where a
small absolute deviation can be a
large percentage of the actual value
due to it befng on the lower skirts of
the photopfc response curve.
Electrical Standards can provide thfs
calibration service.
· The long tenn calibration of the
probes fs very stable due to the
sflfcon photodfode and glass photopic
correction filters. Sfnce the Jl6
itself fs calibrated usfng only a
simple current source and DVM, ft fs
seldom a source of error unless
incorrectly zeroed.
I rec01111end that the J16's be
recalibrated about once a year. The
probes probably should be recalibrated
every sfx months or so--110stly because
calibration techniques are being
improved with time rather than the
likelihood of the probes themselves
-3-
October, 1883 laaue 31
changing calibration. Routine Jl6 and
probe calibration is handled through
Factory Service while special probe
calibrations are done by Electrical
Standards.
3) J6503 Modifications--As
assem"bled, the J6503 has a plastic
window and shiny blue plastic
front which can cause minor
reflections when placed directly
in contact with a CRT faceplate.
For best accuracy the plastic
window should be discarded, the
probe front painted flat black and
the probe recalibrated.
Some early J6503's had glossy black
paint on the internal baffles and no
inner black shield to reduce internal
reflections. This resulted in side
lobes and a significant difference fn
readings with and without the light
occluder often used for CRT
measurements. These can be modfffed
and recalibrated without too much
df ffi cul ty.
4) 2 1/2 Dflft Jl6's--Early Jl6's
having only 1/2 digits are dffffcult
to read accurately, when the reading
are at •20
11
or so as the +l dfgft
ambfgufty amounts to 51. -Also they
have a 12Hz count rate rather than 6
Hz as fn the 3 1/2 dfgft version.
Thfs causes the display to change
faster than the user can detect a
reading for varying lfght fntensftfes.
Both of these shortcomings were
addressed with major modfffcations at
S/N 8052000.
5) N:. Versus Battery Operatfon--
The Jl6 fs available with an Ar. power
supply installed as Option 3 or ft may
be ordered separately to replace the
battery pack as 119-0404-00. Thf s
overcomes three problems--
I) Battery lffe fs short and
recharging tfme is long,
(ARTICLE CONTINUED ON THE NEXT PAGE)

Jl6 OPERATING HINTS (CONT.)
2) the charging current is 1/3
of the operating current;
thus, use of the charger
during operation will not
siginificantly increase
operating time, and
3) the Jl6 zero will be most
stable on the higher
sensitivity ranges when
operated continuously.
Also, the early Jl6's used a three
pin battery charger plug that had
no strain relief and often had the
wires short or break unbeknownst
to the user.
In conclusion, recent Jl6's are
quite stable and should have good
correlation between individual
units if zeroed and calibrated
correctly. Older Jl6's can be
brought up to date relatively
easily.

OF150 LINE FUSE FAILURE MOD
REF: M51508
As a result of the excessive number of
line fuse failures caused by high
transient voltages from the AC line, a
Metal Oxide Varistor (307-0415-00) has
been added to the power supply in
parallel with the spark gap
A30A2E2010.
To install the Varistor, incapsulate
it in shrink tubing (162-9031-00), lay
it on top of A30A2C2010, and solder
the Varistor's leads to the spark gap
leads.

S3200 SERIES SITE LOG BOOK,
062-7232-00
The Site Log Book provides maintenance
personnel with one common place to
record S3200 Series Semiconductor Test
System's information. All S3200
Series system models may use the Site
Log Book.
A new Site Log Book is recommended
annually for each system.
SECTION DESCRIPTIONS
The Site Log Book is divided into
eight major sections. Each section
will contain documentation concerning
one specific area of system
information.
Section I - Information
The information Section identifies
personnel for maintenance, repairs, or
other system responsibilities.
Section II - Logs
The Logs Section is for recording
system maintenance or repair calls.
This section also contains Service
Logs, which should be completed for
-7-
October, 1983 laaue 31
each service call. Documentation
related to system performance is also
included under Uptime Calculation.
Section III -Schedules
The Schedules Section contains several
types of forms to assist in
documenting and scheduling
maintenance. The Schedules Section
should be reviewed soon after the
system is installed. Prior to
finalization of a maintenance plan,
all sections should be compared. This
comparison should be done to check for
conflicts in scheduling. Different
maintenance services should not be
scheduled simultaneously.
Section IV -Configuration
The Configuration Section provides
worksheets for system inventory. The
System Inventory is broken into basic
categories. Tektronix products and
options are separate from computers
and peripherals. The OEM portion
lists many products not manufactured
by Tektronix that may be placed in an
S3200 Series System.
Section V- Software
The Software Section is a very
important part of the Site Log Book.
Because of its importance, the four
portions of this section should be
kept current at all times. Software
modifications, updates, and changes
should be documented in this section.
A system CONFIG.EDT listing, a copy of
the System Formatter, and a copy of
the System Disk directory are located
in the Software Section.
Section VI -Site Spares
System spares provide additional
support at the system site. The Site
Spares Section provides Log Out Sheets
and inventory forms. Users may desire
to use their own forms or methods to
meet their needs.
