DPA-400 - DisplayPort 1.2 AUX Monitor


The DPA-400 1.2 is a pocket-sized device that provides a full DisplayPort version 1.2 AUX channel traffic analysis. DPA-400 1.2 and its GUI monitor, capture and document all messages sent by source, sink or branch devices. The user can evaluate each message either as time-stamped raw data or in parsed form, expressed with the same terminology used by Unigraf CTS Test software and the DisplayPort standard specification.

The DPA-400 1.2 is able to detect and parse all DPCD locations, decode the sideband CH communication messages, and monitor the activity of the Hot Plug Detect (HPD) signal and additional auxiliary input signals. DPA-400 1.2 is USB-powered and measures only 10.5 x 13 x 3.5 centimeters, making it an ideal tool for a laboratory desktop and a snappy companion for a laptop computer.
