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 Analysis Probes, 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.
Analysis probes 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.
