Host High Speed Electrical Test Procedure Revision 1.4

3 Recommended Equipment

The commercial test equipment listed here are base on positive experience by the USB-IF members

in executing the USB high-speed electrical tests. This test procedure is written with a set of specific

models we use to develop this procedure. In time, there will be other equivalent or better test

equipment suitable for use. Some minor adaptation of the procedure will be required in those cases.

Tektronix Digital Oscilloscope:

• This procedure supports Tektronix TDS7404/B or CSA7404/B or TDS7704B, TDS7254/B,

DPO7054, DPO7104, DPO7254, DPO7354, DPO/DSA70404, DPO/DSA70604 and

DPO/DSA70804 series of Digital Phosphor Oscilloscopes.

• Tektronix Probes and accessories (Refer to

www.tektronix.com for complete scope-to-probe

compatibility requirements)

o A DPO7254, DPO7354, TDS7254/B, TDS7404/B, CSA7404/B or TDS7704B or greater

bandwidth oscilloscope is required to test the high-speed USB hosts, devices, or hubs

o A DPO7054 or TDS5034B or greater bandwidth oscilloscope is required to test low-speed

and full-speed USB devices and hubs

o A P6330 or P6248 1.7 GHz differential probe or greater bandwidth probe. For example,

P63301, P7330, P7360, P7380, qty = 2

o Tektronix TCA to BNC adapters, qty = 3

o TDS7000 Deskew Fixture, part number: 067-0405-xx, shipped as a standard accessory to

the oscilloscope.

• 3 ½ Digital Multimeter – Fluke Model 77 or equivalent

Mini-clip DMM lead – one each of black and red

• High-speed USB Electrical Test Fixtures

• Tektronix TDSUSBF signal quality test fixture, qty = 1

o Disconnect test fixture, qty = 1 (source: USB-IF)

o Female Serial B to female Serial A adapter, qty = 1

• Known good HS device – any HS capable device that is on the USBIF integrators list.

• Miscellaneous Cables

o 1M USB cable, qty = 1

o 1.5M USB cable, qty = 1

o Modular AC power cord, qty = 2

• High-speed Signal Quality Analysis Computer

This is the computer that hosts a USB 2.0 compliance host controller for high-speed hub or

device electrical test, or serves as a test bed host for a USB 2.0 host controller under test. The OS
