DisplayPort™ 1.4 Sink Calibration and Test Software (DP-SINK-BSX/DP-SINK)

Developed for Tektronix by Granite River Labs (GRL), DisplayPort 1.4 PHY Sink Calibration and Test software for the Tektronix BERTScope BSX (DP-SINK-BSX) and BERTScope BSA (DP-SINK) provides an automated, simple, and efficient way to test DisplayPort Sink (Receiver) devices per the Jitter Tolerance requirements of the DisplayPort physical layer compliance test specification (CTS) version 1.4 and DisplayPort over USB Type-C 1.0a CTS.

DP-SINK-BSX software automates stressed signal calibration and jitter tolerance testing at all DisplayPort data rates (RBR, HBR, HBR2, and HBR3) with a single setup and runs on any Windows 7 PC or oscilloscope.

DP-SINK-BSX supports all sink devices; USB Type-C display or multi-port adapters, docks, and monitors with either USB Type-C or standard DisplayPort connectors. TP2 and TP3 test point calibration is achieved by simply adjusting the ISI using the Artek CLE-1000-A2.

Link training, compliance, and margin testing through DPCD registers is automated using the Unigraf DPT-200 (reference source with AUX control) for standard connector designs and GRL-USB-PD-C2 for USB Type-C designs. Margin testing stresses the receiver to failure at user-defined jitter amplitude and frequency steps, revealing the true capabilities of your receiver design.

DP-SINK-BSX can be further customized by the user or GRL Engineering using GRL’s full KayaQ automation framework. Contact GRL at [email protected] or through your Tektronix Account Manager for further details.
