MULTI CHANNEL LOGIC ANALYZER
A logic analyzer is an electronic instrument that displays signals in a digital
circuit that are too fast to be observed and presents it to a user so that the user can
more easily check correct operation of the digital system. They are typically used for
capturing data in systems that have too many channels to be examined with an
oscilloscope. Isolation will be provided between the controller & the input signal in So
that the controller will not be damaged due to any high voltage spike. The logic
signals at different channels will be sent serially to the PC using MAX232. VB side
software on the PC will then display the logic levels on the screen. This data can be
stored in the PC & can be seen any time.
