Adjustment Procedure
7. Continue with t
he adjustment process as follows:
NOTE. During some steps, the instrument may appear to be idle for several
minutes while it is processing information internally.
a. If you make an error, such as connecting the wrong input signa l, push the
Return to Previous Screen side bezel button and repeat the previous step.
Push the button multiple times if you need to go back multiple steps.
b. If the oscilloscope fails a step, refer to Troubleshooting at the end of this
section to fix the problem, and then repeat the previous step.
c. If a step fails twice, return to the first step in the adjustment procedure and
try the entire procedure again. If the procedure still fails, it could indicate
a problem with the oscilloscope. Contact Tektronix for technical support
(see the contact information at the beginning of this manual).
8. When the adjustment procedure is complete, the factory dialog box appears,
showing the updated time and date of the last successful adjustment. This
comple
tes the adjustments.
9. Use the Performance Verification procedure to verify that the adjustment
proce
dure correctly adjusted the oscilloscope to operate within specifications.
