TDSUSBF USB 2.0 Compliance Test Fixture Instructions 1

TDSUSBF Test Fixture

The TDSUSBF compliance test fixture is a companion product for use with the

TDSUSB Universal Serial Bus (USB 2.0) Compliance Test Package. The

TDSUSBF enables high quality compliance level measurements of the USB 2.0

devices, hosts and hubs. The test fixture supports tests that measure high, full

and low speed signal quality. It also supports inrush, droop, receiver sensitivity,

packet parameter, suspend, resume, reset, and impedance measurements. All are

mandatory for USB 2.0 compliance.

The fixture is shipped as a single circuit board and is organized into three

sections:

HHigh Speed Signal Quality and TDR

HLow/Full Speed Signal Quality and Inrush Current

HAn active load for droop testing and eight switchable 100 mA/500 mA

passive loads and a dynamic 2 Hz switching 100 mA load.

The boundary between these sections is scored so that you can snap these

sections apart for convenience.

You can use the TDSUSBF with the Tektronix TDSUSB2 USB Compliance Test

fixture which can be ordered either as Option USB for the DPO7000,

TDS5000B, TDS6000B/C, or TDS7000B series, or as an upgrade to these

oscilloscopes. Refer to the TDSUSB2 data sheet on www.tektronix.com for

specific compatibility information.

Accessories

The following accessories are included with the fixture. Refer to the Replaceable

Parts List on page 11 for part numbers when ordering replacement parts.

HInstructions

HCable: USB, short ~12.7 cm (5 in) USB cable (A receptacle to a B plug) for

use with devices with a B receptacle

HAdapter: To adapt an A male receptacle to a mini B male plug
