HP E3491A Pentium Probe

HP E3491A Pentium Probe—At a Glance

The HP E3491A Pentium Probeprovides

a low-cost way to debug embedded

softwareforIntel Pentium

microprocessors. It can also be used

with theHP E2457A Preprocessor

Interface for microprocessor code

disassembly.

Thetargetconnection

The HP E3491APentium Probe connects

to your target microprocessor via a

special connector onthetargetsystem,

or through the HP E2457A Preprocessor

Interface.

The HP 16505A connection

The HP E3491APentium Probe connects

to theHP 16505A Prototype Analyzer via

an Ethernet LAN forremote operation,

or directly forpoint-to-point operation.

The logic analyzer connects to the

HP 16505A through a SCSI connector.

The configuration switches

Usethe switches to configure

communication to the HP 16505A. There

is a guide to these switches on the

bottom of the HP E3491A Pentium Probe.

The status LEDs

LEDs show the statusof the power

supply, the target system, and the

connection to the HP 16505A.

Additonal equipmentrequired

The HP E3491A Pentium Proberequires

Compatibility with other products

The HP E3491APentium Probe and

HP 16505A Prototype Analyzercan also

be used withthe HP E2457A

PreprocessorInterface.
