Microprocessor and Bus-Specific Interfaces
There are a number of microprocessor- and bus-specific interfaces
available as optional accessories. Microprocessors are supported by
Universal Interfaces or Preprocessor Interfaces, or in some cases, both.
Universal Interfaces are manufactured by other vendors. Universal
Interfaces are aimed at initial hardware turn-on, and provide fast,
reliable, and convenient connections to the microprocessor system.
Many use passive probing and do not support inverse assembly.
Preprocessor interfaces are aimed at hardware turn-on and
hardware/software integration, and 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 HP-IB, RS-232-C, RS-449, SCSI, VME, and VXI.
General-Purpose Probing
General-purpose probing connects the logic analyzer probes directly
to your target system without using any interface. General-purpose
probing does not limit you to specific hookup schemes.
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 section.
