Adjustment procedure
Alignments during
warm-up
Alignments are
not run during the 20 minute warm-up period (except for RF
oscillator alignments); the instrument uses default alignment values (if Auto mode
is selected).
NOTE. Instrument performance is not warranted during the specified 20 minute
warm-up period.
Alignments during normal
operation
Once the instrument reaches operating temperature, a full alignment is run every
two hours (for up to two minutes). Alignments can run more frequently if the
operating temperature changes. If an alignment becomes necessary during a
measurement cycle (if Auto mode is selected), the measurement is aborted and
an alignm
ent procedure is run. Once an alignment procedure is completed, the
measurement cycle restarts.
Alignments are not
calibr
ations
Alignme
nts are adjustment procedures run by the instrument using internal
reference signals and measurements. Calibrations can only be performed at a
Tektronix service center and require the use of traceable test equipment (signal
sources and measuring equipment) to verify the performance of the instrument.
