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. 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. 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
