Vertical Test Group Self Test Failing on Agilent MSO8104A

Question asked by Admiral on Apr 28, 2017
Latest reply on May 2, 2017 by algoss

I'm getting "Vertical Test Group" Failed on my Agilent MSO8104A. Looking at the logs shows that all values/voltages are nominal but the test is still flagged as FAILED. Any thoughts on this?
