Linsn card with flickering problem
« on: December 16, 2019, 05:32:00 pm »
Hi
I'm busy with reverse engineering of a LISN card, RV905H.
I use the card in standalone mode without any connection to a "server", when I push the button the LEDWALL steps to predefined patterns, this works!
But sometimes there is a white flickering noise... I measured already the power rails this rails looks good and stable.
When measuring the CLK (this CLK is generated by the FPGA and go through all the LED panels.)
I found some strangs signals... See picture below.

Have any of you suggestions how to future investigate this problem?

A silly question would be have you got the scope probe on X10. :)
CML+  That took much longer than I thought it would.
