Introduction

The USB Analysis Probe module provides a complete interface between any point on the USB and an Agilent Logic Analyzer. The Analysis Probe interface receives the USB serial bit stream and converts it to an understandable parallel bus that is then acquired by the logic analyzer.

The USB Analysis Probe is a passive bus monitor which does not assert any signals on the USB . The USB signals are received with a USB compliant transceiver. The power for the Analysis Probe logic and transceiver is taken from the logic analyzer. Thus the Analysis Probe does not draw power from the USB wire.

The USB Analysis Probe software configures all the logic analyzer menus for compatibility with the USB Analysis Probe. When the configuration file is loaded and the analyzer is set to STATE mode, an inverse assembler is also loaded which decodes USB packets into easy to read mnemonics.

The USB Analysis Probe also provides access to the actual USB wire for both digital and analog measurements. D+, D-, GND, USB Power and the transceiver outputs of VP, VM, and RCV are also provided on the test points.

How to Use This Manual

This manual is organized to help you quickly find the information you need.

• Analyzing the Universal Serial Bus chapter introduces you to the USB Analysis Probe and lists the minimum equipment required and accessories supplied for USB analysis. Characteristics common to state and timing analysis are also detailed.

• The State Analysis chapter explains how to configure the USB Analysis Probe to perform state analysis on your USB .

• The Timing Analysis chapter explains how to configure the USB Analysis Probe to perform timing analysis on your USB .

• The General Information chapter provides some general information including the operating characteristics for the USB Analysis Probe module and the cable header pinout.

Analyzing the Universal Serial Bus

This chapter introduces you to the USB Analysis Probe and lists the minimum equipment required and accessories supplied for Universal Serial Bus analysis. This chapter also contains information that is common to both state and timing analysis.

Before you use the USB Analysis Probe software,

Duplicating the Master Diskette

make a duplicate copy of the master diskette. Then store the master diskette 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 diskette wears out, is damaged, or a file is accidentally deleted.

To make a duplicate copy, use the Duplicate diskette

Accessories Supplied

operation in the disk menu of your logic analyzer. For more information, refer to the reference manual for your logic analyzer.

The USB Analysis Probe product consists of the following accessories:

• The USB Analysis Probe interface hardware

• The inverse assembly and configuration software

on a 3.5 inch diskette.

• This operating manual

Minimum Equipment Required

The minimum equipment required for analysis of a Universal Serial Bus consists of the following equipment:

• A 166x, 167x , 1680/90, 1671x , 1674X, 1655x or 1675x logic analyzer

Signal Naming Conventions

The USB Analysis Probe Switches and Diodes

The Slow Speed Only Switch and LED

• The USB Analysis Probe Product

• A USB target wire

This manual applies to Hardware revisions ACE or later and software revision 3.0 or later.

This operating manual uses the same signal notation as the UNIVERSAL SERIAL BUS SPECIFICATION REVISION 1.0.

The USB Analysis Probe contains one switch and four LEDs

The slow speed switch should be in the ON position (LED ON) when the USB Analysis Probe is on a slow speed only wire or slow speed only segment of the USB. When attached to a high speed segment or mixed segment (slow speed and high speed traffic) the switch should be in the OFF position (LED OFF).

USB Busy LED

Ready LED

VCC LED

The USB Busy LED is lit when the USB Analysis Probe is actively receiving packets from the USB wire. The LED may appear dim if the traffic load is light.

The Ready LED indicates that the on board serial ROM has successfully loaded the FPGA and that the USB Analysis Probe is ready for USB analysis.

The VCC LED on the USB Analysis Probe indicates that power is applied from the logic analyzer to the USB Analysis Probe logic. For correct operation of the USB Analysis Probe the VCC LED must be lit.

Connecting to the USB Analysis Probe

The following explains how to connect the logic analyzer to the USB Analysis Probe for either state or timing analysis:

1. Remove the probe tip assemblies from the

logic analyzer cables.

2. Plug the logic analyzer cables into the USB

Analysis Probe cable headers as shown in the appropriate following tables.

analysis

The USB Analysis Probe can be installed in any segment of the Universal Serial Bus. However, to view all packets from the Host the USB Analysis Probe must be placed between the Host and the USB Hub or USB device. The following steps explain how to install the USB Analysis Probe onto the Universal Serial Bus.

1. Install the logic analyzer cables as described in

the previous section.

2. Plug the USB Analysis Probe IN cable to the

upstream Host or Hub. The USB Analysis Probe OUT connector can be connected down stream to either a Hub or device or it can be left unconnected.

3. Turn on the logic analyzer on so that the VCC

and READY LEDs on the USB Analysis Probe are lit.

NOTE: Connect the USB Analysis Probe to

the USB wire as described in step 2 prior to powering up the logic analyzer.

Setting up the Analyzers installed in the 16500 mainframe.

The logic analyzer can be configured for USB analysis by loading the USB configuration file. Loading this file will load the Universal Serial Bus inverse assembler and configure your logic analyzer for USB analysis.

1. Install the 16500 USB Analysis Probe Software

for the FS4100 flexible diskette in the disk drive of the logic analyzer.

2. Configure the menu to “Load” the analyzer with

the appropriate configuration file (see table below).

Logic Analyzer File name

16555, 16710/1/2 USB555 166x USB660 16550 USB550

3. Execute the load operation to load the file into

the target logic analyzer. NOTE: Do not select ALL

or SYSTEM as the target of the load operation, select the logic analyzer that is connected to the USB Analysis Probe.

Setting up the 167xx Analyzer

The 16600/16700 requires a special install procedure to install the FS4100 software. To accomplish this, insert the diskette labeled 16700/702 Installation disk for the FS4100 into the 16700/702 diskette drive. From the SYSTEM ADMINISTRATION TOOLS select INSTALL under SOFTWARE. From the SOFTWARE INSTALL screen select the FLEXIBLE DISK and APPLY. The package FS4100 will now appear. Select it and then select INSTALL. This

procedure does not need to be repeated. It only needs to be done the first time the USB Analysis Probe is used.

When this has completed restart the logic analysis session and either invoke the Setup Assistant from the logic analyzer screen or load the appropriate configuration file from the Configs/FuturePlus/FS4100 directory. The Setup Assistant will guide you in configuring the logic analyzer. Select FuturePlus from the list on the left of the Setup Assistant screen and then USB from the list that then appears.
