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.
Note:
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.
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
outlet using the provided power cord.
Note:
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.
Step 2
Use the power switch located on the rear panel to turn the Analyzer unit on and
off.
Note:
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.
