Introduction
The LA5034 is a sophisticated 500MHz, 34-channel logic analyzer used for
testing, analysis, and troubleshooting of digital circuits. The LA5034 is
equipped with features found only in more expensive bench type instruments
The use of advanced large-scale integrated circuits, integrated USB 2.0, CPLD,
FPGA, high-frequency digital circuitry, embedded systems, and other
advanced technology, make the LA5034 to be portable, and easy-to-use,
making the LA5034 your best choice in pc-based logic analyzers The
LA5034 is very suitable for electronic measurement engineers, college
students in scientific research and development and teaching assistants.
The User’s Manual describes in detail the operation of the LA5034 as well as
installation of the software.
The LA5034 has a sufficient number of input channels and is capable of
simultaneously observing a lot of information or data flow direction control
information, and in some way of capturing narrow pulse interference.
The LA5034 has the feature of delayed ability to capture the required
observation points around the waveform, in a variety of digital information
capture function.
The LA5034 has adequate memory capacity to be both display error
messages and to find faults in the source state.
The LA5034 has intuitive and flexible displays to facilitate dynamic analysis,
can
transform the information, and the user can use the binary, decimal,
hexadecimal or ASCII that information to facilitate the repair process and
debug.
The LA5034 can be triggered in a variety of ways, can display a very long data
stream, on the basis of the analysis of that part of the information to make
accurate positioning, and capture appropriate information for software analysis
by using its tracking function trigger operation procedures. For hardware,
trigger function can be detected in the system and that the interference and
Burr.
The LA5034 has reliable Burr detection ability. As competition in digital circuit,
the signal crosstalk, interference and power coupling factors, often mixed with
irregular signal in the burr, which will run from an incorrect circuit. The LA5034
can detect through special burr technology to capture and display.
