7.3.2 Monitoring the DisplayPort Aux Channel Transactions in Real Time with the ACA Utilities
Use the following procedures to monitor the DisplayPort Aux Chan transactions with a DisplayPort device in real
time. The procedures assume that the DP device under test is powered up and connected to one of the 980 DP
Video Generator / Analyzer ports. The operation of the ACA is the same when testing a source or a sink.
The operation of the two ACA real time utilities—Aux Channel Analyzer on the embedded 980 GUI and the ACA
Remote Control on the external 980 GUI Manager-- is similar. The screen examples used in this subsection are
from the ACA Remote Control utility on the external 980 GUI Manager exceptions related to the operation of the
ACA on the embedded 980 GUI Manager are noted.
Important Note: You can filter and search through the ACA traces. Procedures for searching and sorting are
provided in a separate subsection further below.
To monitor the DisplayPort transactions:
1. For the embedded ACA utility, touch select the Aux Channel Analyzer on the page 1 (Card Control) of the
Apps panel:
