Circuit Testing

[Lizwi]

Hi.

I have been using oscilloscope to test my CPLD but the circuits programmed used to need fewer channels and my oscilloscope has 4 channels.


Now I am having a circuit that needs 12 channels.
What can I use instead of oscilloscope??

The tool is named logic analyzer.
Easy to find online in various flavors (and for various wallet sizes, too )
