Instrument Serial Numbers

Each instrument manufactured by Tektronix has a serial number on a panel insert or tag, or stamped on the
chassis. The first letter in the serial number designates the country of manufacture. The last five digits of the
serial number are assigned sequentially and are unique to each instrument. Those manufactured in the
United States have six unique digits. The country of manufacture is identified as follows:

B010000 Tektronix, Inc., Beaverton, Oregon, USA
E200000 Tektronix United Kingdom, Ltd., London
J300000 Sony/Tektronix, Japan
H700000 Tektronix Holland, NV, Heerenveen, The Netherlands

Instruments manufactured for Tektronix by external vendors outside the United States are assigned a two digit
alpha code to identify the country of manufacture (e.g., JP for Japan, HK for Hong Kong, IL for Israel, etc.).

Safety

Specific Precautions

Observe all of these precautions to ensure your personal safety and to
prevent damage to either the digitizing oscilloscope or other connected
equipment.

Power Source

The digitizing oscilloscope operates from a power source that will not apply
more than 250 V
supply conductor and ground. A protective ground connection, through the
grounding conductor in the power cord, is essential for safe system operaĆ
tion.

between the supply conductors or between either

RMS

Grounding the Digitizing Oscilloscope

The digitizing oscilloscope is grounded through the power cord. To avoid
electric shock, plug the power cord into a properly wired receptacle where
earth ground has been verified by a qualified service person. Do this before
making connections to the input or output terminals of the digitizing oscilloĆ
scope.

Without the protective ground connection, all parts of the digitizing oscilloĆ
scope are potential shock hazards. This includes knobs and controls that
may appear to be insulators.

Use the Proper Power Cord

Use only the power cord and connector specified for your product. Use only
a power cord that is in good condition.

Use the Proper Fuse

To avoid fire hazard, use only the fuse specified in the parts list for your
product, matched by type, voltage rating, and current rating.

Do Not Remove Covers or Panels

To avoid personal injury, do not operate the equipment without the panels or
covers.

Electric Overload

Never apply to a connector a voltage that is outside the range specified for
that connector.

Do Not Operate in Explosive Atmospheres

This equipment provides no explosion protection from static discharges or
arcing components. Do not operate the digitizing oscilloscope in an atmoĆ
sphere of explosive gases.

Safety

Do Not Service Alone

Do not perform internal service or adjustment of this product unless another
person capable of rendering first aid and resuscitation is present.

Use Care When Servicing With Power On

Dangerous voltages exist at several points in this product. To avoid personal
injury, do not touch exposed connections or components while power is on.

Disconnect power before removing protective panels, soldering, or replacing
components.

Product Description

Before You Begin

The TDS Family Option 13 adds Centronics and RSĆ232 hardcopy (talk only)
capability to the TDS Family of digitizing oscilloscopes. The option consists
of a single circuit board, its attached connectors, and rear panel labels.

The RSĆ232/Centronics Hardcopy Interface allows you to make hard copies
of waveforms (and other onĆscreen information) to a variety of graphic
printers and plotters from the scope front panel.

To make this option work, you must have both the RSĆ232/Centronics HardĆ
copy Interface hardware and Version 2.0 firmware (or future versions)
installed on the oscilloscope.

To ensure the hardcopy feature is working properly, execute the internal
diagnostic routine by doing the following steps:

1. Power on the digitizing oscilloscope.

The oscilloscope automatically executes a short internal diagnostic
routine that checks oscilloscope functions. When finished, the oscilloĆ
scope displays an onĆscreen report of any failed modules or features.

Discharge (ESD)

CAUTION

Electrostatic discharge can damage any semiconductor component
on this oscilloscope option circuit board.

Precautions

When performing any service that requires internal access to the oscilloĆ
scope, follow the following precautions to avoid damaging internal modules
and their components due to ESD.

1. Minimize handling of staticĆsensitive modules.

2. Transport and store staticĆsensitive modules in their static protected
containers or on a metal rail. Label any package that contains staticĆsenĆ
sitive modules.

3. Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap while handling these modules. Perform service on
staticĆsensitive modules only at a staticĆfree work station.

4. Remove anything capable of generating or holding a static charge on
the work station surface.

5. When possible, handle circuit boards by the edges.

6. Do not slide the modules over any surface.
