become active.
Factory preselector data always takes precedence over user-activated
preselected data, unless the user data is explicitly recalled using
RECALL PRSEL PK. For more information on storing and recalling
preselector data, refer to the SAVE PRSEL PK and RECALL PRSEL
PK softkeys.
PRESEL MAN ADJ

For internal mixing the marker must be positioned
above band 0. Set the trace to clear-write mode, place a
marker on the desired point, then press PRESEL
AUTO PEAK. The peaking routine zooms to zero span,
peaks the preselector tracking, then returns to the
original span. To read the new preselector peaking
number, press PRESEL MAN ADJ. Preselector peaking
is available only with resolution bandwidths greater
than 100 Hz.
The automatic preselector peaking routine is not
designed to work when an Agilent 85644A or Agilent
85645A tracking source is used with the spectrum
analyzer.

PRESET
Allows you to adjust the preselector tracking to
maximize amplitude response with either internal or
external mixers. Preselector peaking is only available
with resolution bandwidths greater than 100 Hz.
When the PRESEL MAN ADJ softkey appears under
the menus
AMPLITUDE
start frequency is set equal to or above 2.9 GHz, then
the preselector tracking can be adjusted for internal
mixing.
