4.2 USB Test Ports

The USB Bus uses keyed connectors so that the type A connector joins a cable directed
to downstream devices or to a hub and the type B connector joins a cable directed to an
upstream host controller or to a hub. A USB hub is used to join multiple devices to an
upstream host controller and therefore has both type A and type B connectors.
These ports have both type A and type B connectors so the Analyzer can conveniently
tap a USB branch. To connect your USB branch for analysis, use the SHORT
(3-foot/1-meter) USB cables to insert the Analyzer in place of the existing cables.
Connect one cable to the type A connector and join it downstream to your device or hub.
Connect the other cable to the type B connector and join it upstream to your host or hub.

4.3 AC Power Source

To turn on the system:
Step 1 Connect the Analyzer box to a 100-volt to 240-volt, 50 Hz to 60 Hz, 120 W power

Step 2 Use the power switch located on the rear panel to turn the Analyzer unit on and
Note:
LeCroy Corporation
The Advisor Bus & Protocol Analyzer is not a hub device; it connects to a
USB branch by inserting a non-intrusive, high impedance tap. Because of
the poor signal quality in the middle of a USB cable, LeCroy recommends
using the shortest possible cables so that the total length of both cables
together is less than 6 feet. The USB cables provided with your Analyzer
meet this requirement. When longer cables are used, the Analyzer may
record incorrect data.
outlet using the provided power cord.
The Analyzer is capable of supporting supply voltages between 100-volt and
240-volt, 50 Hz or 60 Hz, thus supporting all known supply voltages around
the world.
off.
At power-on, the Analyzer initializes itself in approximately 25 seconds and
performs an exhaustive self-diagnostic that lasts about 45 seconds. The
Status LED illuminates during the power-on testing and turns off when
testing is finished. If the diagnostics fail, the Status LED blinks, indicating a
hardware failure. If this occurs, call LeCroy Customer Support for assistance.
