Calibrations are marked with numbers from 1 to 47 and, except the
(50M) and TCXO adjustments in the OSC (oscillators) group, should
be carried out exactly in the order as numbered on the panel. The
numbers that are associated with each adjustment are identified as
Setup Number at the title of each of the adjustments in the following
procedure.
Remote adjustments have the range of 1 through 256 with the center
alignment set to 128. Therefore, if you are not sure of the direction, set
the adjustment to 128 and add or subtract from this value. If you have
reached 1 or 256 and were not able to calibrate the range, there is
either a problem with the way you measure the parameter or possibly
there is a problem with the instrument. In either case, do not leave any
adjustment in its extreme setting but center the adjustment and
contact your nearest service center for clarifications and support.
Note in the following procedures that although configuration of the
5251 is done automatically, some of the configurations are shown for
reference only. There is no requirement to change configuration of the
5251 during the remote adjustment procedure except in places where
specifically noted.
