Never use an AC adapter or power cable other than the dedicated ones
supplied by Yokogawa. Using the wrong adapter or cable can result in
damage or injury.
Also, never use the AC adapter that came with the test fixture for any
other device.
● Do not allow any electrically conductive objects to come into contact with
the bottom surface of the test fixture.
● Beware of exposed circuits
Due to the structure of the test fixture, certain components may be
exposed. To prevent injury, remove all jewelry such as rings and
wristwatches. Also, make sure not to touch any exposed connectors or
components.
● Never insert your fingers between the metal plates in the center of the
test fixture and the solder-side of the PCB.
● Do not inadvertently twist or pull the USB cable.
The wires inside the cable can break, causing malfunction.
● When shipping or handling, support the test fixture by the center metal
plates and avoid vibration and shock.
Take extra care not to drop the test
fixture. Also, never carry the test fixture
by the USB cable.
● Due to the structure of the test fixture,
certain components may be exposed.
Take precautions against static electricity
when handling.
1. Checking the Product

2. Product Overview
The test fixture is used together with the USB compliance test software to perform tests
conforming to the USB 2.0 compliance test procedures. The fixture consists of separate
test blocks for the following nine tests: DEVICE SQ TEST, HOST SQ TEST, DEVICE
RECEIVER SENSITIVITY TEST, TRIGGER, INRUSH TEST, LOAD TEST, DROOP
TEST, BACKDRIVE VOLTAGE TEST, AVERAGE CURRENT DRAW TEST. The test
block used differs depending on the test.
Waveforms can be observed by probing the measurement pins and waveform
measurement connectors on the test fixture.
3. Names of Parts
● Take care when handling USB cables and the current measurement loop
attached to the test fixture. Pulling strongly on cables can cause them to
become detached from the test fixture.
● Do not forcefully press the measurement pins and waveform
measurement connectors on the test fixture.

4. Usage Precautions
Safety Precautions
• Do not remove the case
Do not remove the cover from the top of the test fixture or the case on the bottom.
Load resistors inside the cover and adjacent components become dangerously hot.
• In case of abnormalities
If there are any symptoms of trouble such as strange smells or smoke coming from
the test fixture or AC adapter, remove the power cord from the outlet immediately.
If abnormalities occur, please contact your nearest Yokogawa dealer or
representative.
• AC adapter and power cord
Nothing should be placed on top of the AC adapter or power cord. The AC adapter
and power cord should also be kept away from heat sources. When removing the
power cord plug from the outlet, always pull by the plug, never pull by the cord. When
removing the AC adapter output cable from the test fixture, hold by the plug and pull
straight out. Do not pull by the cord. If the cord is damaged, contact your dealer for
replacement.

• Take proper care when carrying
Do not hold by the USB cable. Also, hold the test fixture firmly by the center metal
plates, and do not drop the fixture.
• Extended periods of non-use
Remove the power cord from the outlet.
• Cleaning
When cleaning, remove the power cord from the outlet, then wipe gently with a soft,
dry cloth. Also, never immerse the test fixture in liquid, nor use any detergents or
abrasives. Do not use any volatile solvents such as benzine.
Installation Conditions
