Chapter 1: Overview
The CATC USB Chief Bus & Protocol Analyzer is an invaluable development and
test tool for designers involved with the Universal Serial Bus (USB). When
connected to any USB branch, the USB Chief Analyzer can monitor the bus
activity and display information about the recorded packets. The easy-to-use USB
Chief program operates in the Windows 95® (OSR 2.1), Windows 98®, Windows
98SE®, and Windows 2000® environments.
The USB Chief Analyzer consists of the Bus & Protocol Analyzer unit and USB
Chief software. Not to be confused with the USB bus being monitored, the
Analyzer unit itself is configured and controlled by a personal computer through
a USB port. The Analyzer is connected to a USB branch with a non-intrusive, high
impedance tap. It listens and records relevant signals on the bus and is also capable
of transmission.
The USB Chief Analyzer supports the Universal Serial Bus, version 1.1. The USB
industry standard refers to a cable bus that supports data exchange between a host
computer and a wide range of simultaneously accessible peripherals. The attached
peripherals share USB bandwidth through a host-scheduled, token-based
protocol. The bus allows peripherals to be attached, configured, used, and
detached while the host and other peripherals are in operation.
Please refer to the Universal Serial Bus Specification, version 1.1 for details on
the protocol. The USB specification is available from the USB Implementers
Forum (USB-IF) at
