Microprocessor and Bus Specific Interfaces
There are a number of microprocessor and bus specific interfaces
available as optional accessories that are listed in the Accessories for
Agilent Logic Analyzers. Microprocessors are supported by
Universal Interfaces or Preprocessor Interfaces, or in some cases, both.
Universal Interfaces are aimed at initial hardware turn-on, and will
provide fast, reliable, and convenient connections to the
microprocessor system.
Preprocessor interfaces are aimed at hardware turn-on and
hardware/software integration, and will provide the following:
•
All clocking and demultiplexing circuits needed to capture the
system's operation.
•
Additional status lines to further decode the operation of the CPU.
•
Inverse assembly software to translate logic levels captured by the
logic analyzer into microprocessor mnemonics.
Bus interfaces will support bus analysis for the following:
•
Bus support for GPIB, RS-232C, RS-449, SCSI, VME, and VXI.
General-Purpose Probing
General-purpose probing involves connecting the logic analyzer
probes directly to your target system without using any interface.
General-purpose probing does not limit you to specific hookup
schemes, for an example, as the probe interface does.
General-purpose probing uses grabbers that connect to both through
hole and surface mount components. General-purpose probing comes
as the standard probing option. You will find a full description of its
components and use later in this chapter.
The Termination Adapter
The optional termination adapter allows you to connect the logic
analyzer probe cables directly to test ports on your target system
without the probes.
