Foreword
Explaining the LSA1000
There are two manuals that explain the LSA1000.
This, the Ope rat o r’ s Man ual, takes you through
the initial steps and gets you started using the
instrument. It explains basics such as how to
connect to a PC and use the software tools
supplied. Once f amiliar wit h the LSA1000’s basic
operation, use the accompanying Remote Control
Manual. It contains detailed descriptions of all
the remote commands used to operate the
LSA1000 from the computer.
Chapter 1 describes warranty, maintenance agreements,
service and return procedure.
Chapter 2 covers the instrument’s architecture, as well as
the fundamental technical concepts behind the LSA1000, to
show how these concepts have been integrated to deliver
superior performance.
Chapter 3 gives operating environment and safety
information.
Chapter 4 covers the connection requirements for LSA1000
and host PC, using the Ethernet.
Chapter 5 offers a step-by-step process to get you started
using the LSA1000 and its software tools.
Appendix A gives the product’s detailed technical
performance specifications of the product, and recommends
optimum operating conditions.
Appendix B is the source code for the Net-Con program.
Appendix C offers a general explanation of how the
instrument’s standard parameters are computed.
Appendix D provides several real-life program examples
you can use with LSA1000.
Appendix E provides suggestions forms that welcome your
input for improving both the product and the manuals.

Foreword
LSA1000: Legacy of the Oscilloscope
In this publication and its companion, the
LSA1000 Remote Control Manual, references are
to be found to functions not directly applicable to
the LSA1000. Some examples are references to
"time/div", "cursors", and "display".
Their presence in dedicated LSA1000 manuals is owing to the
legacy of LeCroy DSOs (Digital Storage Oscilloscopes) in the
development of the LSA1000. Although the current practicability
of these functions may not immediately be apparent, the basic
concepts to which they adhere remain valid for the LSA1000,
and the functions are supported by remote control commands.
Moreover, in order to maintain compatibility, the LSA1000’s
remote commands have been made a subset of the commands
for the LeCroy digital oscilloscopes.
Terminology borrowed from the oscilloscope should thus be
understood to refer to the LSA1000 conceptually, as if it
possessed an oscilloscope display. It should be noted, for
example, that all commands that refer to "divisions" on a DSO
are applicable to the LSA1000: there are eight divisions full scale
in the vertical (voltage) direction, and 10 divisions in the
horizontal (time) axis.
