Brief Procedures First, the CAL menu is displayed. Second, the adjustment sections are verified. Third, a signal path compensation is run and is verified. Figure 1-2: Verifying Adjustments and Signal-Path Compensation When doing steps f and g, do not turn off the oscilloscope until signal- path compensation completes. If you interrupt (or lose) power to the instrument while signal-path compensation is running, a message is logged in the oscilloscope error log. If such a case occurs, rerun signal
