Adjustment Procedures
This chapter contains adjustment information for your oscilloscope.
The voltage and timing references inside the oscilloscope are very stable
over time and should not need routine adjustment.
If the instrument fails performance tests (refer to Performance Tests on
page 4--17) then adjustment may be required.
If periodic calibration is one of your requirements, a general rule is to verify
performance and make adjustments (only if needed) every 2000 hours of
operation or once a year if the oscilloscope is used infrequently.
After removal and replacement of a module due to electrical failure, you must
either perform an adjustment or not, depending on the module replaced. Modules
listed as customer replaceable have adjustment listed if required. Modules not
listed as customer replaceable must be installed and adjusted by Tektronix. See
Table 6--7 on page 6--64.
If your instrument requires adjustment, adjustment must be performed by a
Tektronix Service Center. See Contacting Tektronix on page xvi for information
on contacting Tektronix Service Support.
