Infiniium USB Test Option E2645A, N2854A, N2855A, E2683A

Introduction

- Recognized by the USB-IF for official compliance testing

- Fast electrical compliance testing

- USB-IF MATLAB script execution inside the Infiniium oscilloscope

- Award-winning Infiniium ease‑of‑use

- Test fixtures for low, full, and hi‑speed compliance

The Infiniium USB Test Option provides a fast and reliable way to verify USB electrical specification compliance for USB 2.0 devices, hosts, and hubs. The Infiniium USB test option executes the official USB-IF MATLAB scripts with MATLAB’s runtime engine embedded in the oscilloscope. Test procedures for Keysight Technologies, Inc. equipment can be found on the USB-IF website: www.usb.org/developers/docs.

Features

With the Infiniium USB Test Option, you can take the Infiniium oscilloscope you use for everyday debugging and use it to verify USB electrical parameters with the same testing scripts the USB-IF created for official compliance testing at designated workshops. The Infiniium USB Test Option allows you to test all facets of electrical compliance of your device, host, or hub quickly and easily. Low, full, and hi-speed tests require compliance with signal quality, inrush current, droop, drop, and backdrive voltage tests. Hi-speed USB requires compliance with an ad­ditional suite of tests. Tests can be executed directly from the scope interface under the Analyze menu. The single menu structure of the Infiniium USB Test Option provides a level of simplicity not found with other vendors’ multi-tiered menu structures for executing tests and documenting results.

One SQiDD (signal quality, inrush, droop/drop) test fixture is included with the software in the test option package. A set of six hi-speed test fixtures for signal quality, receiver sensitivity, TDR, and host disconnect can be

ordered separately as part number E2649A.

Benefits

In the past, pre-compliance testing in a lab environment involved capturing the data with an oscilloscope, transferring it to a PC, and post-processing it with a soft­ware program of choice. The Infiniium USB Test Option has simplified the process by installing a run-time version of MATLAB in the scope and integrating the USB Test Option into the Infiniium oscilloscope’s menu structure. Test results are just one mouse-click away.

Once the test is executed, the test results appear on the Infiniium display in an .html window. Each test also automatically saves the .png, .html, and .tsv files required by the USB-IF.

The higher data rates associated with hi-speed USB 2.0 demand a measurement sys­tem that will not interfere with your device/host/hub operation by loading the system. The award-winning InfiniiMax probing system, which is compatible with Infiniium oscilloscopes, provides unmatched signal fidelity—ensuring your measurement system does not load the signals under test, thus not compromising the specifi­cation margins for passing the electrical signal quality tests. The InfiniiMax probing system has been approved by the USB-IF for compliance testing.

The set of six hi-speed test fixtures are highly manageable in a test environment due to their smaller size. The six fixtures allow you the flexibility to run different tests concurrently when you have more than one host, hub, or device to verify for compliance.
