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).

DROOP TEST
Switches the load current between 0 mA and 100 mA at cycles of approximately 2 Hz.
Connector used: CN5 (receptacle B)
INRUSH TEST
SW5 switches between TEST ON, OFF, and DISCHARGE.
When measuring the inrush current, attach a current probe to the current measurement loop.
Cable and connector used: CN16 (cable A) and CN20 (receptacle A)
Note
Do not apply a current of 1 Arms or greater to Vbus.
TRIGGER
Cable and connector used: CN11 (cable A) and CN15 (receptacle A)
HOST SQ TEST
Cable used: CN2 (cable A)
DEVICE RECEIVER SENSITIVITY TEST
SW8 switches RL1(RL2) between INIT and TEST.
• When Set to INIT
The D+ and D− signals are routed between CN30 and CN25.
• When Set to TEST
The D+ signal is routed between CN29 and CN25, and the D− signal is routed between CN28
and CN25.
Vbus is always connected between CN25 and CN30 regardless of the SW8 setting.
Cable and connector used: CN25 (cable B, or mini B cable with the /MN1 option) and CN30
(receptacle B)
DEVICE SQ TEST
SW8 switches RL2 (RL1) between INIT and TEST.
• When Set to INIT
The D+ and D– signals are routed between CN34 and CN31.
• When Set to TEST
The D+ and D– signals are routed between CN31 and the 45 Ω terminator.
Vbus is always connected between CN31 and CN34 regardless of the SW8 setting.
Cable and connector used: CN31 (cable B, or mini B cable with the /MN1 option) and CN34
(receptacle B)
BACKDRIVE VOLTAGE TEST
Measure D+, D−, and Vbus voltage at CN18.
Connector used: CN13 (receptacle A)
AVERAGE CURRENT DRAW TEST
This test block is used for “Device Framework Testing.” Measure the Vbus current between TP3 and
TP4.
For testing methods, see “C. Device Framework Testing” in the Universal Serial Bus Implementers
Forum Full and Low Speed Electrical And Interoperability Compliance Test Procedure.
6. Preparing for Waveform Measurement
Affixing the Probe Attachment
• PBA2500 Active Probe (Model 701913, Sold Separately)
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.

CAUTION
When inserting a probe with the attachment affixed into the waveform measurement
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 two-
layer configuration. The connectors come in two layers upon shipment.

Accessory connectors stacked
in two layers
• Affix the dedicated attachments to the PBA2500 and PBD2000 probes, then insert into the
specified pins of the second layer of connectors. For the locations and numbers of pins, see the
procedure manuals for the individual tests.

7. Troubleshooting
Troubleshooting
If servicing is necessary, or if the fixture is not operating correctly after performing the corrective
actions below, contact your nearest YOKOGAWA dealer.
Description
Possible Problem
Corrective Action
LED1, 2, or 3 does not turn ON. Using an AC adapter of a
voltage outside the rated range.
Use the AC adapter that came
with the fixture.
Faulty connection between the
AC adapter and the CN100
connector of the test fixture.
Check the connection between
the AC adapter and connector
