Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

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 allbuscycles,includingprefetches,are sent to the
logic analyzer as theyoccur. 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 skewis 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 accidentallydeleted.

Equipment
Supplied The HP E2444A Preprocessor Interface consists of the following
equipment:
•The preprocessor interface hardware, which includes the
preprocessor interface circuit card and cable assembly.
•The inverse assemblysoftware on a 3.5-inch disk.
•This user’s guide.
Note The preprocessor interface socket assemblypins are covered at the
time ofshipment with either a conductive foam wafer or a conductive
plastic pin protector. This is done to protect the delicate gold-plated
pins of the assemblyfrom damage due to impact. When you’re not
using the preprocessor interface, protect the socket assemblypins from
damage bycoveringthem with the foam or plastic pin protector.
Equipment
Required The minimum hardware required for analysis of an 80386DX/DXL
target system consists ofthe followingequipment:
•An 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 80386DX/DXL Preprocessor Interface and Inverse
Assembler (HP E2444A).

Installation
Overview The followingprocedure describesthe major stepsrequired to perform
measurements with the HP E2444A Preprocessor Interface. The page
numbers listed in the various steps refer you to sections in the manual
that offer more detailed information.
Caution To prevent equipment damage, remove the power from both the logic
analyzer and the target system whenever the preprocessor interface or
microprocessor is being connected or disconnected.
1. Ensure the State/Timing jumper isconfigured appropriatelyfor
state or timing analysis(see page 1-4).
2. Connect the 80386DX/DXL preprocessor interface to the target
system (see page 1-6).
3. Plugthe logic analyzer cables into the preprocessor interface
pods as listed in table 1-1 (see page 1-7).
4. Load the logic analyzer configuration and inverse assembler for
the specified logic analyzer (see page 1-11).
5. For timing analysis, select the configuration menu of the logic
analyzer and select Timing as the analyzer "Type"(see page 2-20).
HP E2444A Setting Up the HP E2444A
80386DX/DXL Preprocessor Interface 1-3

J2 Jumper and
J3 Connector There is one jumper and one additional connector on the HP E2444A,
J2 and J3 (see figure 1-1). J2 is the State/Timing jumper. J3contains
additional signals which can be monitored with the General Purpose
(GP) Probes supplied with your logic analyzer.
The State/Timing
Jumper (J2) The State/Timing jumper allows you to configure the HP E2444A
preprocessor interface for either state or timinganalysis. For state
analysis,this jumper must be open (jumper removed);for timing
analysis,the circuit must be closed (jumper installed).
When the J2 jumper is in place (closed), the buffers on the
preprocessor interface are flow-through buffers, adding onlyminimal
skewto signals. When the jumper is removed, the buffers behave as
latches,which capture and hold data based on the assertion ofADS
and READY.
A31-2and D31- 0are latched address and data when the jumper is
open. In State-Per-Clock mode, it is best to close the jumper J2 so that
the buffers are flowthrough, and all signals sampled are relative to
each other. Ifyou use State-Per-Clock mode with J2open, valid
addressand data appear two statesafter ADS and READY are
asserted, respectively.
J3 Connector The J3 connector contains the HOLD, INTR, and NMI signals (see
figure 1-1). To viewthese signals,use the GP probes supplied with
your logic analyzer, and connect these signals to an unused logic
analyzer pod. Note that a signal ground connection is not provided or
required, since the logic analyzer is alreadygrounded when the other
pods are connected.

Connecting to
the Target
System
The followingsteps explain howto connect the HP E2444A
Preprocessor Interface to your target system:
Caution To prevent equipment damage, be sure to remove power from both the
logic analyzer and the target system whenever the preprocessor
interface or microprocessor is being connected or disconnected.
1. Remove the 80386 microprocessor from its socket on the target
system and store it in a protected environment.
Caution Serious damage to the target system or preprocessor interface can
result from incorrect connection. Note the position ofpin A1 (figure
1-1) on the preprocessor interface connector and the target system
socket prior to inserting the connector in the socket. Also, take care to
align the preprocessor interface connector with the socket on the target
system so that all microprocessor pins are making contact.
2. Plug the preprocessor interface connector into the
microprocessor socket on the target system.
Note Ifthe preprocessor interface connector interferes with components of
the target system or ifa higher profile is required, additional plastic pin
protectors/extenderscan be added. Plastic pin protectors/extenders
can be ordered from Hewlett-Packard usingthe part number
1200-1605. However, any 132-pin PGA IC socket with an 80386
footprint and gold-plated pins can be used.
3. Plug the 80386 microprocessor into the socket on the
preprocessor interface board. The socket on the preprocessor
interface board isdesigned with low-insertion-force pinsto allow
you to install or remove the microprocessor with minimum force.
4. Applypower to the logic analyzer first,and then to your target
system. The logic analyzer must be powered up first, since it
supplies power to the preprocessor interface.

Connecting to
the HP E2444A Connect the logic analyzer cables to the preprocessor interface as
shown in table 1-1 (following pages). Designations such as P1 refer to
connectors on the preprocessor interface, while Pod 1 refers to a logic
analyzer pod.
Figure 1-2 (page 1-10) shows the relative locations for the logic
analyzer cards.
Power Up /
Down Sequence When poweringup, the logic analyzer must be powered up first, and
then the target system. The logic analyzer provides the power to the
active circuits on the preprocessor interface; unpowered circuits may
cause improper operation of the target system.
When poweringdown, the target system should be powered down first,
and then the logic analyzer.
