Setting Up the HP E2444A
Introduction
The HP E2444A Preprocessor Interface provides a complete interface
between an 80386DX/DXL target system and the following HP logic
analyzers: HP 1650A, HP 1650B, HP 1652B, HP 1660A/61A,
HP 16510A, HP 16510B, HP 16511B, HP 16540A,D with two
HP 16541A,D Expansion Cards, HP 16542A (Master Card and four
expansion cards), or HP 16550A. The preprocessor interface connects
the signals from the 80386DX/DXL target microprocessor to the logic
analyzer inputs, and generates all status and clock signals required by
the software for inverse assembly of the 80386DX/DXL instruction set.
The 80386DX/DXL Preprocessor Interface operates in the bus mode.
In the bus mode all bus cycles, including prefetches, are sent to the
logic analyzer as they occur. All coprocessor cycles on the local bus
are also captured.
The 80386DX/DXL configuration software on the flexible disk sets up
the format specification of the logic analyzer for compatibility with the
80386DX/DXL microprocessor. It also loads the inverse assembler
routine for obtaining displays of 80386DX/DXL data in assembly
language mnemonics.
The preprocessor interface can be used for timing analysis as well as
state analysis. The State/Timing jumper on the preprocessor interface
board determines which type analysis is obtained. In the Timing
position, a minimal amount of skew is added between the signals.
Duplicating the
Master Disk
Before you use the HP E2444A software, use the Duplicate Disk
operation in the disk menu of your logic analyzer to make a duplicate
copy of the HP E2444A master disk. Store the master disk and use the
back-up copy to configure your logic analyzer. This will help prevent
the possibility of losing or destroying the original files in the event the
disk wears out, is damaged, or a file is accidentally deleted.
