Witam Kolegów. Ostatnio w pracy na warsztacie znalazłem oscyloskop Tektronix 7603. Pomijając skrzywioną gałkę podstawy czasu i uwzględniając działającą lampę postanowiłem zaopiekować się nim, co po krótkich negocjacjach udało się zrobić. Po naprawieniu mechanizmu gałki podstawy czasu i przywróceniu napięcia +18V z zasilacza (zabrakło go gdy wyschnął elektrolit) na ekranie pojawiły się przebiegi. Reszta napięć jest w porządku więc poza tym zasilacza nie ruszałem. Do sedna: - napisy określające wartości wzmocnienia i podstawy czasu reagują na kształt sygnału i wzmocnienie - gdy sygnału nie ma są we właściwych miejscach, po podaniu np. sinusa zaczynają "falować" z amplitudą odpowiadającą wzmocnieniu - amplituda sygnału mierzonego "faluje" z bliżej nieznaną częstotliwością Co może być przyczyną takiego zachowania ? Z góry dziękuję za udzielone odpowiedzi. Dla jasności załączam krótki film przedstawiający problem: https://filmy.elektroda.pl/33_1492958457.mp4 oraz instrukcję serwisową: 830526

Later production of rackmount oscilloscopes are provided with support posts between the individual plugin compartments. A post or posts must be removed if
a multiwidth plug-in is to be installed. To remove a
post, unfasten the screws that secure it at the top and
bottom of the plug-in housing.

NOTE
Two types of crt graticules have been used in some
Tektronix orcillorcopes. One graticule has 0% and
100o1'risetime reference points that are separated by
6 vertical graticule divisions. The other graticule has
the 0% and 100% risetime reference points separated
by 5 vertical divisions. ln your manual, illustrations
of the crt face or risetime measurement instructions
may not correspond with the graticule markings on
your oscilloscope.

Raster
Display
A raster-type
displaycan be usedto effectivelyincrease
the apparentsweep length. For this type of display,the
trace is deflected both vertically and horizontally by
sawtooth signals.This is accomplished the 7603 by

Normally,the time-base
unit in the
verticalcompartmentshouldbe set to a slowersweeprate

unit in the horizontal

the
numberof horizontaltracesin the raster

This type of raster display could be used to provide a

To provide a stable rasterdisplay.both time-base

provided for the time-baseunits when they are in the

external triggeringmust be used.
Also, blanking is not provided from the time-base

A further feature of the Zeros Logic and Memory is the
ldentify function. lf 10 units of column current are
encoded by the plug-in unit along with row 3 during
time-slot 1, the Zeros Logic and Memory produces a
negative-goingoutput pulse at pin 1 which switches the
Column Data Switch and Row Data Switch to the ninth
channel. Then, time-slot pulses 2 through 9 encode an

ObtainingReplacement
Parts
NOTE
When selecting replacement parts, it is important to
remember that the physical size and shape of a
component may affect its performance in the instrument, particularly at high frequencies. All replacement parts should be direct replacements unlessit is
known that a different component will not adversely
affect i nstru m en t perform ance.

Even though unwired boards are available without
components, use of the completely wired replacement board is recommended due to the large number
of components mounted on most of the boards.
Most of the circuit boards in this instrument are
mounted on the chassis; pin connectors are used for
interconnection with other circuits. Use the following
procedure to remove the chassis-mountedcircuit boards

the R7603 in an installation where it is not correctly
supported at the rear, as the instrument may be damaged.
Slide-Out Tracks
WA N'Y'flG
During rackmount installation, interchanging the left
and right slide-out track assemblies defeats the extension stop (safety latch) feature of the tracks. Equipment could, when extended, come out of the slides
and fail from the rack, possibly causing personal injury
and equipment damage.
When mounting the supplied slide-out tracks; inspect
both assemblies to find the LH (left hand) and RH
(right hand) designations to determine correct placement. lnstall the LH assembly to your left side as you
face the front of the rack and install the RH assembly
to your right side. Refer to the rackmounting instructions in this manual for complete information.

NOTE
lf the rails of the rack are tapped, drill out these three
holes with a 0.196-inch drill.
lf this instrument is mounted in a shailow rack where
the rear mounting brackets must extend behind the
instrument, a maximum of 26 inches clearance
behind the front rails is required.
