DPA-400_prod_NEW

DisplayPort™ AUX Channel Monitor

DPA-400 AUX Channel Monitor now includes DSC, FEC, LTTPR registers decoding and supports DP 2.0.

DPA-400 with the AUX Channel Monitor GUI provide a compact, pocket sized tool for recording and analyzing DisplayPort AUX channel traffic. They enable the user to monitor, capture and document the DPCD reads and writes and the MST Sideband Channel Communication over a DP link. Compatible with all DP versions from DP 1.1 to 1.4a, 2.0 and HDCP 1.3 and 2.3 messaging. DPA-400 is also compatible with DisplayPort Alternate Mode in USB Type-C interface.

An Essential Tool for R&D Debugging

DPA-400 is a very valuable tool for monitoring the AUX Channel handshake between the source and the sink and revealing any root causes of possible failures.It can be placed between DP Source and upstream port of DUT or between downstream port of the DUT and DP Sink.

 

Raw and Parsed Message Data

DPA-400 GUI detects and parses all DPCD locations used in all DP versions from 1.1 to 2.0. It decodes as well the HDCP 1.3 and 2.2/2.3 messages and DP Sideband Channel Communication messages.  This makes it straightforward for the engineer to follow the Sink / Source communication, the CTS test execution and refer it to the requirement of the standard. AUX Channel Monitor GUI lists every AUX Channel events and DPCD content both as as time stamped raw data and in a parsed form. The details are explained with the same terminology used by the relevant VESA standard and Unigraf CTS Test report. The complete logs can also be stored for later use or shared with colleagues as universally portable HTML files.

AUX Channel Monitor GUI and FW with DP 2.0 support and HDCP 1.3 and HDCP 2.2/2.3 support

DPA-400 GUI detects and parses all DPCD locations used in all DP versions from 1.1 to 2.0. It decodes as well the HDCP 1.3 and 2.2/2.3 messages and DP Sideband Channel Communication messages. The activity of the Hot Plug Detect (HPD) signal and optional user defined input signals will also be tracked and time stamped.

USB-C DisplayPort Alt Mode

DPA-400 AUX Channel Monitor is compatible also with DisplayPort Alternate Mode in USB Type-C interface. With the Unigraf provided cable, you can connect the DPA-400 between any two USB-C devices and monitor the AUX Channel transactions related to the DP Alt mode.

Easy to Use

DPA-400 is a small sized, USB-powered device. It measures only 10.5×13×3.5 centimeters. The compact size and light weight makes it an ideal tool for a laboratory desktop. It is a snappy companion to a compatible laptop computer or tablet.

Unigraf AUX Channel Monitor affects the signal quality as little as possible. DPA-400 delivery includes a custom cable for bypassing the main stream lane signals. This ensures that the signal integrity of the high speed bus will not be compromised with monitoring.
