Solution approved by the USB-IF read the full press release.



  • Performs Compliance Tests for any USB Power Delivery or Type-C design
  • Tests USB Power Delivery 
Bi-Phase Mark Coded (BMC) 
Physical Layer (PHY), Protocol (PROT), and Power Provider/Consumer (POW) Compliance.
  • Supports USB Power Delivery Protocol, Compliance, Decode, and Debug along with Electrical Measurements.
  • Supports USB-PD Alt Modes 
such as DisplayPort, Thunderbolt 3, and MHL
  • Runs on Keysight, Rohde & Schwarz, Tektronix or Teledyne LeCroy Windows Based Oscilloscopes



GRL’s USB Power Delivery (GRL-USB-PD) Compliance Test Software is the world’s first oscilloscope-based software tool designed for testing to the USB Power Delivery (USB-PD) specification.

GRL-USB-PD software, when used ‘stand-alone’ on any Windows based oscilloscope, provides a simple and efficient way to perform USB-PD electrical parametric and protocol measurements. GRL-USB-PD provides waveform visibility and protocol analysis making it ideal for design and debug of USB Type-C Power Delivery silicon and end products.


When used with GRL’s USB Type-C Test Controller Hardware (GRL-USB-PD-C1), GRL-USB-PD provides a complete automated solution for Compliance Testing to the USB Power Delivery Compliance Plan.


GRL has been a contributor to the USB Power Delivery Specification and Compliance Working Groups since mid-2014. With GRL’s USB-PD Compliance Solution, you can perform the required USB-PD Compliance tests in your own lab before attending a workshop or sending your device to a lab for Compliance.

For most new designs using the USB Type-C Connector, the USB PD Specification provides the handshaking -contract needed, not only for power delivery, but also ‘Alt Mode’ entry/exit for other technologies such as DisplayPort and Thunderbolt 3.

GRL’s flexible controller hardware and software solution supports Alt Mode link negotiation and Power Delivery handshaking needed for other tests such as high speed PHY testing.

GRL-USB-PD provides an essential analysis and compliance tool for the design, debug, and compliance testing of USB Power Delivery and Type-C designs.
