Adjustment Procedures
This chapter contains adjustment information for your instrument.
Adjustment Interval
The voltage and timing references inside the instrument 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 instrument is used infrequently.
Adjustment After Repair
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--76.
Adjustment
If your instrument requires adjustment, adjustment must be performed by a
Tektronix Service Center. See Contacting Tektronix on the Copyright page of
this manual for information on contacting Tektronix Service Support.
