Applications

• Compliance testing of USB battery chargers with permanent cable
• Compliance testing of USB battery chargers with detachable cable
• External power supply (EPS) design and Compliance testing to IEC62684 specification
• System integration and validation of data enabled mobile telephones that use USB 2.0 interface for battery charging
• Manufacturing test
• The Tektronix MSO/DPO5000, DPO7000C, and DPO/DSA/MSO70000C series oscilloscopes enabled with option USBPWR provide automated setup for design validation and compliance testing of USB battery chargers and external power supplies. The Tektronix USBPWR solution serves the needs of engineers designing USB based battery chargers and external power supplies, as well as those validating the electrical compliance of the devices to the new IEC62684 Specification and USB 2.0 Battery Charger specification v1.1.

Automated Testing – Save Time and Resources

There is no longer a need to be an expert on IEC62684 testing procedures. Remembering the exact steps to take each measurement is time consuming and often requires going back to the IEC62684 specification and the USB battery charging specification. USBPWR Automated Solution takes the guesswork out of conducting compliance testing.

For compliance testing, it is difficult to remember the test procedures or to set up the correct parameters, such as applying the correct record length and sampling rates. USBPWR Automation Solution provides standard specific details and predefined scope settings for each measurement, so the user does not need to be an expert. USBPWR Automated Solution minimizes the setup initialization problems, reduces the complexity of executing USBPWR tests and enables you to test designs faster.

USBPWR automates the complete set of measurements to be performed using a real-time oscilloscope for devices with permanent cable as well as designs with detachable cable. Measurements include:

• Ripple Voltage for the combination of the following settings:
• AC frequency: 47 Hz, 50 Hz, 60 Hz, and 63 Hz
• AC voltage: 90 V, 120 V, 207 V, and 253 V
• Load: 0%, 25%, 50%, 75%, and 100% of the rated output current
• Temperature: 0 °C, 25 °C, and 45 °C
• AC Voltage Frequency Component
• Maximum Slew
• Common Mode Voltage at the following frequency bands:
• 100 kHz-400 kHz
• 1 kHz-100 kHz
• 1 MHz-100 MHz
• 400 kHz-1 MHz

USBPWR Results section helps design engineers look at the test results quickly and clearly for pass or fail summary. It provides visual representation of pass/fail status and test execution status in color codes.

The USBPWR automation generates thorough .MHT/.XLS/HTML reports that capture the details of each test including Limits, Measured Value, Pass/Fail Results, Margin, common mode voltage plots, frequency component plot, etc. It also captures test execution time, and hyper-links to saved test waveforms for each test. Report generation also provides features such as report appending, auto incrementing report naming, inserting user comments, etc. Reports appending feature enables adding results from different test conditions and test scenarios, and create a single-printable-report for sharing the results.
