INTRODUCTION
This manual is divided into four sections as follows:
Section 1 is the main reference section which contains a detailed
description of the operation of each function.
Section 2 is a tutorial for new users (or for existing users needing
examples of how functions operate).
The Appendices provide additional detail on some of the more
complex functions and on some of the theoretical aspects of digital
storage.
The Specifications give detailed technical specifications for the
instrument, plus service and warranty details.
N.B. The DSA524 can use either an oscilloscope or a personal
computer (IBM compatible) as the display device. This manual only
covers use with an oscilloscope. To use a PC as the display device
the "DS-PC Link" software package must be purchased, an additional
manual is supplied with this software.
FIRMWARE LEVEL
From time to time small revisions may be made to the
firmware of the DSA524 (the firmware is the ROM based
program code for the unit).
The firmware level is displayed briefly whenever the unit is
first switched on (and when SET 'SCOPE is used) as DSA524
X.XX, where X.XX is the firmware level.
This issue of the operating manual applies to units with a
firmware level of 2.71 and above.
IT IS VERY STRONGLY RECOMMENDED THAT NEW
USERS START BY FOLLOWING THE TUTORIAL.
