Adjustment Procedures
This chapter contains the factory adjustment procedures for the TDS3000C series
oscilloscopes. Only qualified personnel should perform adjustment procedures.
Read the Service Safety Summary and the General Safety Summary before
performing any service procedures. Also refer to the chapter Operating
Information for information about using the oscilloscope.
NOTE. The voltage references inside the oscilloscope are very stable over time
and should not require routine adjustment. Before performing any procedure in
this chapter, do the Performance Verification procedures (found in the Specifica-
tions and Performance Verification technical reference, available on the Web at
www.tektronix.com/manuals) to check whether or not the oscilloscope meets
specifications.
Successful completion of this adjustment procedure automatically updates the
instrument Calibration Due date and time. Successful completion of the
Performance Verification procedure does not update the instrument Calibration
Due date and time.
