TDSUSBF USB 2.0 Compliance Test Fixture Instructions 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: H High Speed Signal Quality and TDR H Low/Full Speed Signal Quality and Inrush Current H An 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.

For receiver sensitivity testing, use attenuators to increase the channel amplitude resolution. TDSUSBF USB 2.0 Compliance Test Fixture Instructions TDSUSBF Test Fixture Installation To use the test fixture, refer to Figure 1 on page 6, and do the following: CAUTION. To prevent damage to the test fixture, always work at a static-approved workstation when handling the fixture. 1. Set the fixture on a nonconductive work surface. CAUTION. To prevent damage to TDR heads, the board must be powered on in the following sequence. 2. To operate various relays, the TDSUSBF high-speed signal quality section requires a 5-volt power supply. Depending on the jumper selection on the test fixture, you can select one of the following power options: H USB host-supplied Vbus power. H User-supplied 5-volt power supply. The external power supply must be capable of providing 500 mA. Recommended or equivalent: ITE Power Supply, Ault Inc., part number PW10DEA0503F01. To select user-supplied 5-volt power, place the jumper between the center pin and the pin marked JACK of J91. Connect the power supply cable to the DC Power In jack, J35 located at the bottom of the board. To select USB Vbus power, place the jumper between the center pin and the pin marked USB of J91. Connect a USB cable from the Host supplying Vbus power to J92. 3. Check that either the TEST or INIT LED is on. If it is not, remove the power supply cable from the DC Power In jack or from the USB connector, and check for shorts. 4. Place the switch S6 in the INIT position. The INIT status LED illuminates. 5. Connect the board for specific tests as described in Table 2 on page 7. TDSUSBF USB 2.0 Compliance Test Fixture Instructions 3 TDSUSBF Test Fixture 6. Set the DUT (Device Under Test) to the proper test state. For example, in a TDR upstream test, the DUT must be configured to SE0_NAK test mode. Otherwise, DUT transmissions can damage test equipment connected to the fixture. For all TDR tests, you should verify with a DMM that the DC bias level is less than 10 mV from D+ to ground and from D-- to ground. 7. Place the switch S6 in the TEST position. Verify that the TEST status LED is on. 8. Perform the test steps as required for your specific test. 9. After finished testing, place the switch S6 in the INIT position and disconnect the power supply cable from the DC Power In jack or disconnect the USB cable providing power to the test fixture. 4 TDSUSBF USB 2.0 Compliance Test Fixture Instructions TDSUSBF Test Fixture Connections and Switch Settings Use Figure 1 on page 6 and Table 2 on page 7 to prepare the fixture for specific tests. NOTE. Other Tektronix probes may also be suitable. Refer to the Test Equipment section of this document to verify compatibility of alternative probes. For more tests, the following oscilloscope configuration is recommended: CH 1--P6248 Differential probe connected to D+ and D-- (High speed) or P6245 single-ended probe connected to D+ (Low Speed (LS)/Full Speed (FS)) CH 2--P6245 single-ended probe connected to D-- (LS/FS) CH 3--On the adjacent channel trigger source (LS/FS), P6245 single-ended probe connected to D+ for full speed testing, D-- for low speed testing CH 4--Current probe for Inrush measurements Switch S6 (Init/Test) The Initialize and Test switch (S6) is a two-position switch used to place the test fixture into initialize status or to test configurations for the following tests: H Device high speed TDR H Device high speed receiver sensitivity H Device high speed signal quality For upstream high speed signal quality testing: There are two sets of stake pins in the high-speed signal quality segment. The set of stake pins (J310) adjacent to the relay pads are intended for use in Signal Quality testing. The set of stake pins (J34) closest to the A receptacle is intended for use in Packet Parameter, Suspend, Resume and Reset tests. In the initialize position, the signal is routed through the fixture, from the input to the output connectors to permit placing the DUT into test packet or other test modes. In this mode, the signal is not present on the signal quality pins (J310) next to the relay pads until the INIT/Test switch is placed into the test position. To verify whether the signal is present in INIT mode, place your probe on the set of stake pins (J34) next to the A receptacle. Return the probe to the signal quality pins to conduct the signal quality test. In the test position, the signal is passed from the DUT and is terminated into precision 45 ohm resistors on the fixture. To probe the signal, connect the middle two header pins located near the relay pads.

Eight separate passive loads, #1 to #8, are switchable between 100 mA and 500 mA. WARNING. To avoid personal injury, do not touch the load resistors when using the 500 mA load positions. The load resistors can become very hot. The droop test load is an active load that switches between an open circuit condition and 100 mA, at approximately a 2 Hz rate. All loads connect through B-type receptacles that are mounted on the back of the test fixture. NOTE. Switch numbers do not follow load numbers. For example, Switch 4 controls Load #2. See Table 4 for the correct switch/load combinations. Use Table 4 and Figure 1 on page 6 to configure loads for specific tests.
