USB-FE02-V01-X - Teledyne LeCroy

Introduction

The Teledyne LeCroy USB Embedded Probe is a portable pod

and cable assembly that allows probing of low speed,

full-speed, and high-speed USB protocols in setups that do

not expose external USB connectors and cables. The probe

can capture either HS/FS/LS at normal USB voltages, or

ICUSB Low and Full speed signaling.

Supported protocols are:

• Low-speed and Full-speed USB 1.1 protocols

• Low-speed, Full-speed, and High-speed USB 2.0

protocols

• Low-speed and Full-speed Inter-chip USB protocols

The probe can be used with any Teledyne LeCroy analyzer

that supports USB 1.1 and USB 2.0 capture, including both

CATC- and Catalyst-based products.

USB Embedded Probe

Quick Start

Components

USB Embedded Probe components are:

• Teledyne LeCroy USB Embedded Probe

with non-removable USB “A” cables

• Probe Lead Assembly (2)

• Solder-in resistors (10) for probe tips, 45.3 ohms

• Solder-in header pins (10)

• Flying-lead micrograbber (6)

[hooks probe tips to header pins on DUT PCB]

• High-speed USB-B terminator

Probe and Lead Assembly

3Description

The USB Embedded Probe allows Teledyne LeCroy PSG

Protocol Analyzer systems to capture Low-, Full-, and

High-speed USB protocols. An LED indicates whether the

probe is powered.

USB: The interface uses standard USB type A plug

connectors (USB Mobile uses mini-A to Standard-A adapter).

Connect Power Supply “A” plug to USB “A” Port on the

computer or to USB power supply. Connect the other “A”

probe plug to the Teledyne LeCroy USB protocol analyzer “A”

receptacle.

Leads: For low- and full-speed use, the lead set may be

connected directly to the USB device using a header pin or

may be soldered directly to the device pins.

For high-speed use, 45.3-ohm resistors must be

used to isolate the lead set from the USB D+ and D- signals.

These resistors may be pressed into the end of the lead set

and soldered to the device.

The micrograbber probe tips may be used to connect

to ground, VDD IO, and low- or full-speed USB D+ and D-

signals. The micrograbber may not be used to connect to the

high speed USB D+ and D- signals.

For the Inter-Chip USB application, connect the lead

set to the Inter-Chip connector on the USB probe. Connect

the D+ lead to the D+ signal, the D- lead to the D- signal, the

GND lead to device ground, and the VDD lead to the device

IO voltage pin (1.0 V to 3.3 V).

For the USB 2.0 application, connect the lead set to

the USB 2.0 connector on the probe. Connect the D+ lead to

the D+ signal, the D- lead to the D- signal, and the GND lead

to device ground. Note: For high-speed mode, the D+ and D-

leads must be connected through the 45.3-ohm resistors.

Terminator: For high-speed mode only, connect USB-B

terminator to analyzer “B” port.

Capture: After the Probe is set up, the analyzer should be

able to capture USB traffic as if it were tapping a normal

cable connection between host and device.

USB Speed: For standard USB level signals, the five-pin

connector labeled “USB 2.0" is used. For Inter-Chip

Low-Speed and Full-Speed, the connector labeled Inter-Chip

is used.
