Tektronix 502 series, Instruction Manual

Page: 3 / 114

PREFACE
We have tried to provide you with the best instrument we can.
In doing this we sometimes make changes in our products after the
instruction manuals have been printed. Many changes are made to
give you the benefit of the latest circuit improvements devloped in
our engineering department, and to accomodate improved com­
ponents as they become available. Our Test and Calibration En­
gineers sometimes hand tailor the circuits to provide optimun in­
dividual performance.
When a particular instrument is changed in any manner, its
manual is corrected accordingly. That is why the instrument serial
number is written on the title page of this manual. If you need
repair parts for an instrument, refer to the manual that belongs to
that particular instrument.
This manual begins with a list of Specifications, so that you will
know the characteristics of your instrument. The second section
provides information on cooling and connecting the power trans­
former for various input voltages. The third section gives you some
of the principle ways in which you can operate your instrument.
Next is the Circuit Description, where the circuitry of your instru­
ment is described in a detailed form. The Maintenance and Recali­
bration sections are last. Here you will find information on trouble­
shooting and repairing your instrument and on carrying out a re­
calibration of the instrument, if necessary, in the field.
We hope that you will find your instruction manual useful. Refer
to it often. We welcome comments.
