About this edition
This is the second edition of the
HP 54520 and 54540 Series
Oscilloscopes Service Guide.
Edition dates are as follows:
First edition, April, 1994
Publication number 54542-97015
Printed in USA.
New editions are complete
revisions of the manual. Update
packages, which are issued
between editions, contain
additional and replacement pages
to be merged into the manual by
you. The dates on the title page
change only when a new edition is
published.
A software or firmware code may
be printed before the date. This
code indicates the version level of
the software or firmware of this
product at the time the manual or
update was issued. Many product
updates and fixes do not require
manual changes; and, conversely,
manual corrections may be done
without accompanying product
changes. Therefore, do not expect
@ one-to-one correspondence
between product updates and
manual updates.
The following list of pages gives
the date of the current edition and
of any changed pages to that
edition. Within the manual, any
page changed since the last edition
is indicated by printing the date
the changes were made on the
bottom of the page. If an update is
incorporated when a new edition
of the manual is printed, the
change dates are removed from
the bottom of the pages and the
new edition date is listed on the
title page.
