Complete USB PD Compliance Tester and development tool for USB Power Delivery
Made by Europe’s foremost USB experts MQP Electronics, the MQP Packet-Master USB-PDT is the world's first all-in-one comprehensive Power Delivery Compliance Tester, for testing protocol, measuring transmitter signal quality, receiver quality and interference rejection, and power load testing. The USB-PDT has been designed in conjunction with the USB-IF Power Delivery Compliance Plan. It is a complete Compliance Tester and development tool for USB Power Delivery, incorporating Analyzer, Exerciser, Compliance Tester, PD VBUS Generator, PD VBUS Load, VBUS Voltage and Current Monitor functions. The unit performs comprehensive PHY, Protocol and Power Compliance Tests on PD devices, and PHY and Protocol Tests on PD Cable Marker chips.
The base unit of the MQP Packet-Master USB-PDT has been conceived to be as flexible as possible by incorporating a plug-in module design. It comes complete with GraphicUSB, an easy-use graphical Windows application for driving and reporting on the Compliance Tests and capturing and displaying every detail of power delivery interactions. ‘Power Delivery’ is a specification allowing USB ports to provide power in a more flexible and adaptable way. The industry standard BMC version uses two-way signaling on the CC wire of a USB C-cable. The Packet-Master USB-PDT behaves as one end of a power delivery link. It can emulate the behavior of an initial Downstream Facing Port (DFP) or Upstream Facing Port (UFP) in controlled ways, and can confirm the responses of the connected Unit Under Test (UUT). It is also designed to perform all the required protocol and PHY Compliance Tests on Electronic Cable Markers.
In Exerciser mode, the USB-PDT behaves as a Provider, Provider/Consumer, Consumer or Consumer/Provider, and the operation can be manually controlled to perform all usual PD operations, including Requests, Swaps, Hard Resets and BIST Mode Requests. Simultaneously, an Analyzer Capture may be performed to see how the UUT responds. The Analyzer functionality is always available, but an additional plug-in module is required to allow analysis of power delivery between two external PD devices.
Virtually any non-compliance with the protocol, timings, signal quality, or power control will be revealed, and a detailed description of the problem displayed. The Tester is built around a 250MSa/s ADC and DAC, combined with a number of other critical resources. Because of its unique design approach, the USB-PDT can be easily updated to meet new PD specification requirements, by using different plug-in modules.
The Packet-Master USB-PDT’s plug-in module design concept has the following advantages for connecting test devices:
- USB-PD connectors can be damaged by handling. If a connector becomes damaged, simply replace the plug-in module.
- The Type-C receptacle on the plug-in is itself a user-replaceable item.
- Different connector styles are available for USB-PD use. Swapping plug-in modules provides the flexibility required.
One important capability of the Tester is to run an Eye Diagram test as specified in the Compliance Plan. The Tester will establish PD communication with the UUT, transmit a BIST Mode 2 request, and during the 30-60ms continuous transmission resulting, will capture samples of the waveform from the UUT. The UUT may be a PD device or an electrically marked Type-C cable. The samples are plotted against the defined mask, with an indication of any places where the mask is intersected. The other specification parameters (rise-time, fall-time, bitrate, and bitrate drift) are also calculated and displayed – and highlighted if out of specification.
