Table 4-2 (page 4-6) lists the calibration that should be performed fol-
lowing the replacement of 690XXB/691XXB subassemblies or RF com-
ponents.

LABEL NOTATION The calibration procedures include many references to equipment in-
terconnections and control settings. For all 690XXB/691XXB refer-
ences, specific labels are used to denote the appropriate menu key,
data entry key, data entry control, or connector (such as
CW/SWEEP
SELECT or RF OUTPUT ). Most references to supporting test equip-
ment use general labels for commonly used controls and connections
(such as Span or RF Input). In some cases, a specific label is used that
is a particular feature of the test equipment listed in Table 4-1.
