ADJUSTMENT
Introduction
This adjustment procedure is to be used to restore the
oscilloscope to original performance specifications. Ad­
justment need
not be performed unless the instrument
fails to meet the requirements listed in the Specification
section of this manual, or the Performance Check cannot
be completed satisfactorily.
Completion of all adjustment steps in this procedure
ensures that the instrument will meet the performance
requirements listed in the Specification section. However,
to fully ensure satisfactory performance, it is recommend­
ed that the Performance Check be performed after any
adjustment is made.
Tektronix Field Service
Tektronix, Inc. provides complete instrument repair
and recalibration at local Field Service Centers and the
Factor Service Center. Contact your local Tektronix Field
Office or representative for further information.
Test Equipment Required
The following test equipment, or equivalent, is required
for complete adjustment of the oscilloscope. The test
equipment performance requirements listed are the
minimum necessary for accurate adjustment. Substitute
equipment must meet or exceed the stated requirements.
All test equipment is assumed to be operating within
tolerance.
