Adjustments
Adjustments are usually required on a yearly basis. They are normally performed
only after a performance verification has indicated that some parameters are out
of specification. Performance verification must be completed after any repairs that
may have altered the characteristics of the E-Series E4412A and E4413A power
sensors. The E-Series E4412A and E4413A power sensors can be returned to
Keysight for adjustments. To arrange the return, contact the “Sales and Technical
Support” on page 10.
