Safety Precautions

To ensure safe and correct operation of the fixture, you must take the safety precautions given below.
The fixture’s protective functions may not work if used in a manner not described in this manual. The
test fixture is a dedicated instrument for the DL9240/DL9240L. Yokogawa bears no responsibility for,
nor implies any warranty against damages occurring as a result of failure to take these precautions.
The following safety symbols and wording are used on the test fixture.

Warning: handle with care. Refer to the user’s manual or service manual. This symbol

appears on dangerous locations on the instrument which require special instructions for
proper handling or use. The same symbol appears in the corresponding place in the manual
to identify those instructions.

Hot surface

Make sure to comply with the following safety precautions in order to prevent accidents
such as an electric shock which impose serious health risks to the user and damage to the
instrument.

WARNING

• To prevent shock or fires, only use the AC adapter and power cable supplied by
Yokogawa specifically for the test fixture. Also, connect a power supply that meets the
specifications of the AC adapter.

Insert the power cable securely into the plug inlet on the AC adapter, and connect the

output cable securely to the test fixture’s power connector.

Power cable

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.

CAUTION

• 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.

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

CAUTION

• 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.

General Handling Precautions

• Do not place anything on top of the test fixture

Never place other instruments or objects containing water on top of the test fixture.
Doing so can lead to malfunction.

• Do not apply shock to the test fixture

Never apply physical shocks to the connectors, switches, or other components.

• 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

Install the fixture so that the following conditions are met.

• Flat horizontal location

• Well ventilated location

• Place the test fixture on a stable, horizontal surface. Also, always orient the fixture with the
component side up.

• Maintain a gap of 10 cm or more on all sides of the test fixture.

5. Test Blocks

WARNING

• If you set SW1 to SW4 to 500 mA when Vbus is supplying the LOAD TEST connectors
(CN7 to CN9), the load resistors will become extremely hot. Make sure you do not touch
the load resistors.

• Since the load resistors of the LOAD TEST blocks get hot during the Droop and Drop
tests, after finishing these tests, immediately remove the USB cables connected to
connectors CN7–CN10 and disconnect the Vbus power supply from the upstream port, or
turn OFF SW1–SW4.

LOAD TEST

Four blocks (1 to 4) are available for the LOAD test. You can switch the load current between 100

mA, OFF, and 500 mA using the switch for each of the blocks (SW1 to SW4).

Affix the attachment (model B8080JP or B8080JQ) that came with the probe as shown in the

diagram below.

• PBD2000 Active Probe (Model 701923, Sold Separately)
Affix the attachments (model B8080JP, 2 pcs.) that came with the probe as shown in the diagram

below.

connector, do not apply vibration or shock to the probe.

Waveform Measurement Connector

• As for the waveform measurement connectors (CN3, CN12, CN17, CN18, CN26, and CN32),
insert the accessory connectors into the connectors already installed on the test fixture in a two­layer configuration. The connectors come in two layers upon shipment.
