HP E2434B Intel 80C186EB and 80C188EB Preprocessor Interface

Product Summary

The HP E2434B preprocessor interface provides an easy way to connect an HP logic analyzer to a target system using the Intel 80C186EB and 80C188EB.

Product Features

• All necessary clocks are generated by the preprocessor ensuring that the data is captured at the correct time.

• Software is shipped with the product that automatically configures the logic analyzer by generating labels for address, data and status signals. Included with the software is a disassembler that displays execution traces in 80C186 microprocessor mnemonics.

• Instructions that are prefetched, but not executed, are marked in the trace display.

• Each preprocessor provides unbuffered timing analysis for all signals.

• When using QFP versions of the chip, the preprocessor provides probing points to take parametric measurements.

Pods Required
Five pods allow timing measurement of all processor signals

Note: Each preprocessor has three connectors available for state 
analysis with additional connectors for timing analysis for all 
signals.  For disassembly, three pods must be used.  All signals used 
in disassembly can be double probed for state and timing analysis.

Adapters
The three state analysis connectors are terminated on the preprocessor.
For timing analysis, one termination adapter is required per pod.
PLCC adapters are included with the product.  Also available are: 
PLCC/PGA IC chip carrier socket and PGA/PLCC adapter.
As an alternative, general purpose probes may be used.

Signal Line Loading
100 kW plus 12 pF on all lines except AS
50 kW plus 22 pF on AS
