Logic Sniffer hack improves signal integrity


Tarloth designed this cool hack to improve signal integrity of the Open Bench Logic Sniffer. Instead of using the standard 1×18 pinheader, he used a dual row 2×18 header. One row is connected to the board, while the other is connected to GND.

Unused signal pins are jumpered to GND using the extra header row. This improves signal integrity on the used channels. If this hack is used with a standard IDC cable, every channel wire has a GND wire on either side of it inside the cable, further improving signal integrity.
