7313JR7313 FEATURES
The Tektronix 7313/RJ313 Oscilloscope is a solid-state instrument designed for general-purpose application where
display storage is desired along with high performanceconventional (non-store)operation. This instrumenthas three plug-in
compartments that accept Tektronix 7-Series plug-in units
to form a complete measurement sysrem. The two plug-in
compartments on the left are connected
to the vertical deflection system. The right plug-incompartment is connectedtothe
horizontal deflection system. Eleczronic switching between the vertical
plug-in compartments allow a multi-tracevertical
display. The flexibility of this plug-in feature
and the variety af plug-inunits available allow this system to be used for many
applications.
The cathode
ray tube is a direct view. bi-stablestorage tube having an 8 x 10 division display area divided into two
4 x 10 division storage screens, The storage screens are independently controlled for split screen applfcations. A non-storing
area to the leftof the storage screens permits
beam location without disturbing a stored display. Regulated dc power supplies
assure that performance
is not affected by variations in line voltage and frequency, or by changes in load due to varying
power requirements of the plug-inunits.
The 7313/R7313 operates from a 115 volt or a 230 volt nominal line voltage source.

AC POWER SOURCES. This instrument is intended to
be operated from a single-phase earth-reference power
source having one current-carrying conductor (the
Neutral Conductor) near earth potential.Operation from
power sources where both current-carrying conductors
are livewith respecttoearth (suchas phase-to-phaseona
three-wire system) is not recommended, since only the
Line Conductor has over-current (fuse) protection within
the instrument.

OPERATING VOLTAGE
The7313/R7313 can be operated from either a 110-volt
or a 220-volt nominal line-voltage source. In addition,
three operating ranges can be selected within each
nominal linevoltage source. Usethe following procedure
to obtain correct instrument operation from the line
voltage available:
1. Disconnect the instrument from the power source.

CAUTION
This instrument may be damaged if operated with
the Line Selector set to the incorrect positions for
the line voltage applied.
3. To convert from 110-volts to 220-volts nominal line
voltage,orvice versa, removethevoltage-selector jumper
and replace it with the spare jumper stored on the pins
adjacent to voltage selector area (see Fig. 1-1). The
jumpers are color coded to indicate the nominal voltage

operationand redfor 220-volt nominaloperation.Change

PLUG-IN UNITS
The 7313lR7313 is designed to accept up to three
Tektronix 7-series plug-in units. This plug-in feature
allows a variety of display combinations and also allows
selection of polarity,sensitivity,display mode, etc.tomeet
the measurement requirements. In addition, itallows the
oscilloscope system to be expaned to meet future
measurement requirements.Theoverallcapabilitiesofthe
resultant system are in large part determined by the
characteristics of the plug-in selected. Refer to the
Tektronix Products catalog for specifications of plug-in
units currently available.
To install a plug-in unit into one of the plug-in
compartments,align theslots inthetopand bottomofthe
plug-in with the associated guide rails in the plug-in
compartment. Pushthe plug-in unitfirmly intotheplug-in
compartment until it locksintoplace.Toremoveaplug-in,
pull the release latch on the plug-in unit to disengage it
and pullthe unit out of the plug-in compartment. Plug-in
units can be removed or installed without turning off the
instrument power.
All of the plug-in compartmentsdonothave to befilled
to operate the instrument; the only plug-ins needed are
those required for the measurement to be made. At
environmental extremes, excess interference may be
radiated into or out of the instrumentthroughthe plug-in
compartments. To reduce such interference, or to meet
EM1 specifications on factory equipped Option 3 or field
EM1 modified instruments, all unused plug-in com-
partments must be covered with an EM1 shielded blank
plug-in panel. Order or use only Tektronix Part No.016-
0155-00. One is required for each unused compartment.
When the 7313/R7313 is calibrated inaccordance with
the calibration proceduregiven intheservice manual,the
vertical and horizontal gains are normalized. This allows
calibrated plug-in units to be changed from one plug-in
compartment to another without recalibration. However,
the basic calibration of the individualplug-in unitsshould
bechecked when they are installed inthissystemtoverify
their measurement accuracy. See the operating instruc-
tions section of the plug-in unit instruction manual for
verification procedure.
The plug-in versatility of the 7313/R7313 allows a
variety of display modeswith manydifferentplug-in units.
Thefollowing information is providedtoaidinplug-in unit
selection.
To produce a single-trace display, install a single-
channel vertical unit (or dual-channel unit set for single-
channeloperation) in eitherof thevertical compartments;
for dual-trace displays, either install a dual-channel
vertical unit inoneofthevertical compartmentsor installa
single-channel vertical unit ineach vertical compartment.
A combination of a single-channel and dual-channel
vertical unit allows a three-trace display; likewise, a
combination of two dual-channel vertical units allows a
four-trace display.
Non-delayed single-trace displays can be obtained
with a single-trace time-base unit.
A dual-trace time-base
unit must be used for delayed-sweep displays.
X-Y displays can be obtained in two ways with the
7313/R7313 system. If a 7B-series time-base unit is
available that has an amplifier feature, the
X signal can
either be routed through one of the vertical units via the
internal-trigger pickoff circuitry to the horizontal system,
orconnected totheexternal horizontalinputconnector of
the time-base unit. Then, the vertical signal
(Y) is con-
nected to the remaining vertical unit. Also, a 7A-series
amplifier plug-in can be installed inone of the horizontal
compartments for X-Y operation.
Special purposeplug-ins mayhavespecific restrictions
regardingthe plug-in compartments inwhich they can be
installed.This information will begiven in the instruction
manuals for these plug-ins. Refer to the Tektronix
Products catalog for additional information on plug-in
unit selection.
NOTE
Later production of rackmount ocilloscopes are
providedwith support posts between the individual
plug-in compartments.
A post or posts must be
removedifa multi-widthplug-inisto
be installed. To
removea post, unfasten the screws that secureitat
the top andbottom of the plug-in housing.
