Analog Discovery 2 Logic Analyzer

[vc26]

Hi,

Recently, I'm unable to look at more than 1 signal on the Analog Discovery 2 logic analyzer at a time. I'm trying to see 5 of them at the same time and if I have more than one channel connected, all of them become zero. Has anyone experienced this problem before? I've had all 5 signals before which is why this is an odd occurance-- is my Analog Discovery 2 broken?

 

Thanks!

Hello,

Make sure to have proper ground connection between the AD and the circuit under test.

What are the voltages levels of the signal you are looking at? You could use the scope inputs to verify this. (Connect the scope negative input to ground.)
