1 Overview
GRL-USB-PD-A1 can be used to analyze behavior between any USB Type-C based device
like Apple Mac’s, Chromebooks and Android phones, Thunderbolt 3 docks, DisplayPort
adapters, Qualcomm Quick Charge AC adapters, USB PD power banks, Cable E-Markers, etc.
Using passive adapters, the GRL-USB-PD-A1 can also check for power and USB Power
Delivery protocol communication over Apple Lightning connectors, and analyze charging
behavior over USB micro-B and Type-A connectors.
GRL-USB-PD-A1 Analyzer connected between two USB Type-C ™ devices captures the
voltage / current information of the VBUS / CC / VCONN signals exchanged between the USB
Type-C ™ devices. The captured data is transmitted to the control PC connected to the USB
Micro-B port. The GRL-USB-PD-A1 software decodes the captured data and gives a graphical
representation of the voltage and current signals captured.
USB Type-C ™ and USB-C ™ are trademarks of USB Implementers Forum.
1.1 Features
1.1.1 Voltage and Current of VBUS / CC1 / CC2 Signal Analysis
The VBUS / CC1 / CC2 signal can be measured to the precision of 1 millisecond accuracy.
The software performs a detailed analysis of Power Delivery message, VBUS voltage and
Current change.

1.1.2 Power Delivery Message Decode
The contents of the captured PD messages are displayed in detail in accordance with the USB
PD Specification.
