  • 3458A boots up with "move JM132 and cycle power".

    Moving JM132  causes no change so instrument is stuck in this loop. Has anyone seen this and a fix?

  • peak-to-peak is described as cumulative for 34465A but is it really?

    The peak to peak description in the "Compatibility and Differences: 34465A and 34410A..." says it is cumulative in the 34465A model but it does not seem to behave that way. It suggests (and the operating guide uses it...
