Using ADV7619 (or other HDMI Rx) as an HDMI 'tester'

Hi there,

 

I'm wondering whether using some of the advanced diagnostics of the ADV7619 along with variations in EQ settings would allow for a rudimentary HDMI tester.  For instance, is there any method of running a small algorithm that moves through the EQ strengths so that one could assess how strong/weak the HDMI TMDS signals are?  This may allow an end customer the ability to produce a series of logs that could tell some information about the cabling/system connections.  I see this app note:

And I wonder whether there is any means of doing any further testing than this.

 

Thanks for your insight,

-Paul
