conditions, and a user-defined set of search conditions. The unit can also be triggered by an
externally supplied signal. On-board memory provides a path for externally supplied data or
timing information to be recorded along with bus traffic.
Real-time USB event detection information is available via an external DB37 connector, making
many control, timing, and recovered signals available externally. These signals can be probed
and used by other circuitry.
The Inspector USB analyzer is designed to turn any 386/486 or Pentium class PC (including
laptop and notebook as well as desktop PCs) into a USB test station. The PC itself does not need
to have a USB interface. The Inspector package includes the stand-alone Inspector box, an
External Interface Breakout Board with a 37-pin ribbon cable, USB and parallel port cables, an
AC to DC power converter, a sophisticated software program running under Microsoft Windows
(3.1, 95, and NT versions), and comprehensive product documentation (including on-line help).
The Inspector analyzer has a built-in high impedance USB probe and several status LEDs. The
analyzer
monitors the two USB wires (D+ and D-) and translates the raw differential data into a
single NRZI bit stream. It samples the data with the recovered synchronized clock, and stores the
resulting bit stream on disk. The analyzer
also detects and reports the static bus conditions
Suspend, Resume, Reset, and Idle.
The Inspector software scans the collected data and displays it in several meaningful formats.
The user can view the data as a continuous stream, or as complete transactions. In continuous
mode, the analyzer fills the entire display line with data; in transaction mode, each line is
dedicated to one bus transaction, such as token, data, or handshake.
The Inspector software provides a powerful search function that enables investigation of
particular bus events, with the software identifying and highlighting specific events such as Bad
PID, Undefined PID, Bad CRC, Bad Stuffing Bits, Missing Frames, etc.
In addition to immediate analysis, the user can print any part of the data and save all or selected
portions of the data on disk for later viewing. The program also provides a variety of timing
information.
The Inspector USB analyzer comes with a one year warranty and hot-line customer support.
