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
