EMI/EMC Chamber-Ready USB-PD Dual Role Power & Data Stimulus Tester: GRL CR-DPWR

GRL Platform Solutions Team — Fri, 27 Mar 2026 05:01:22 GMT

EMI/EMC validation for USB-C and USB Power Delivery (USB-PD) devices presents a unique set of engineering challenges. Devices must be evaluated under high power transfer, dynamic protocol negotiation, and high-speed data activity—conditions that often introduce noise and heat that lead to unstable loading or uncontrolled cabling effects that compromise the accuracy of traditional test equipment.

HDMI® 2.2 Engineering Challenges, Sideband Validation, and the Nova-S03 Solution

While HDMI® 2.2 specification resolves many of the integration constraints inherent to HDMI® 2.1 Specification copper interconnects, it introduces a new set of engineering challenges. The jump to uncompressed 8K, variable refresh rates (VRR), and multi-stream transport (MST) is pushing modern video systems to their physical and protocol limits.

Extending the Reach of Display Connectivity with DisplayPort™ 2.1b Specification

GRL Platform Solutions Team — Fri, 27 Mar 2026 05:01:16 GMT

Showcased at CES 2025, DisplayPort™ 2.1b introduced the DP80LL low-loss cable that featured three times more length than the previous passive DisplayPort 2.1 cables while sustaining 80Gbps bandwidth over the UHBR20 transmission mode. The new, active cable was designed to reduce signal attenuation. Enabling ultra-high bit rates across longer distances improved the versatility of the cable, opening up new possibilities for flexible workstation setups and VR/AR applications.
