PicoScope 3425 Not Reading

[delkin]

I have been working with a PicoScope 3425 recently, making 30+ recordings with no issues. Suddenly, I am no longer getting any readings from the scope, just a 30Hz signal bounding between -0.6V and 0V, even when all the probes are detached. No recorded spikes occurred, just paused the recording and resumed to the 30Hz signal. Attached is an image of the signal. I've tried connecting to each of the 4 probes with no luck. Any insight on this issue would be greatly appreciated.

Hi delkin,

This could be a fault in the Scope. I would suggest that you send your enquiry into our helpdesk at support@picotech.com where our tech support team will be able to help you further.
