USB Power Delivery Test Equipment

Packet-Master USB-PDT

The USB-PDT is a Power Delivery Compliance tester. It is pictured here fitted with the PDT-BT2-CON1 plug-in for testing on C-Type connector equipped Units Under Test

In this form it is capable of performing the complete suite of USB-IF Power Delivery Compliance Tests for both Cable E-Marker and PD Devices.

The USB-PDT is intended for use by compliance test houses and USB-IF workshops, and will also be found to be of great value to developers of Power Delivery Devices and E-markers, as it can save its cost many times over in potential failure of compliance testing done for the purpose of certification.

Tester Functionality

The USB-PDT Tester is equipped with the following resources:

  • Test Suite runs automatically with minimal intervention
  • A device with no issues can typically be tested in around 10 minutes
  • BMC Transmitter and Receiver employing 250Ms/s digital signal processing
  • Capability of Displaying BMC signal Eye Diagram with approximately 15 bit resolution
  • Capability of generating signal distortions for running the specified Interference Rejection tests required.
  • 100W PD VBUS Generator, automatically controlled by the tester
  • 100W PD VBUS Load, automatically controlled by the tester
  • VBUS Voltage and Current Measurement. Voltages are effectively made at the UUT end of the calibrated test cable supplied
  • A comprehensive Power Delivery Engine to allow the tester to behave as any knind of appropriate Port Partner during testing, and also to apply unusual test conditions to the Unit Under Test
  • Automatic Analyser Capture During Testing
  • External Power Supply Provided
  • An Exerciser capablity is currently in development

Eye Diagram

The digital signal processing nature of the USB-PDT receiver allows it to display an eye diagram plotted using the exact algorithm specified in the USB PD Compliance Plan. Around 15-bit resolution ensures an accurate and clean eye diagram; very important during compliance.

Analyser Capture

During testing, the entire sequence of PD messages is captured and displayed. Each event is analysed in the Details pane. Every bit field is analysed, described and any potential non-compliances are highlighted.SOP', SOP'', SOP'_debug and SOP''_debug messages are also displayed. The locations of the packets and the scope captures, together with voltage and current, are shown in the zoomable timeline.

VBUS scope captures are made at appropriate points in the testing, and these can be displayed, along with the related message positions. Each scope capture has a mask added to illustrate the adherence or otherwise of the waveforms to the specification.

Plug-ins for Packet-Master USB-PDT

Currently a plug-in module (PDT-BT2-CON1) is available specifically for the PD Specification rev 2 compliance test.

Coming shortly are:

  • A plug-in for the PD Specification Rev 3 compliance test and Type-C Functional Testing

The C-Type connector is mounted on a mini-board to make it user-replaceable. This is a huge advantage if the connector becomes worn or damaged.
