Scale Type
Log Lin
Scales the vertical graticule divisions in logarithmic units when
Log
is
underlined. Logarithmic units may range from 0.1 to 20 dB per
division. When
Lin
is underlined, the vertical divisions are linearly
scaled and the default amplitude units are volts. The top of the display
is set to the reference-level value and the bottom graticule becomes zero
volts. (Each division of the graticule is one-tenth of the reference level
in volts.) Pressing
Scale Type
always sets the units specified for the
current amplitude scale. When
Power On
is set to
Preset
and
Preset Type
is set to
Factory
, pressing
Preset
or powering on the analyzer sets the
default units. The fastest sweep time available when
Lin
is selected and
the detector is set to average (
Det/Demod
,
Detector
,
Average
) is 8
milliseconds.

Presel Center
Agilent E4404B, E4405B, E4407B and E4408B only. Adjusts the
frequency of the preselector filter (above 2.85 GHz) to optimize the
amplitude accuracy at the active marker frequency. With
Input Mixer
(Ext)
selected and the Mixer Type set to Presel (preselected),
Presel
Center
adjusts the frequency of the external preselector filter to
maximize the amplitude at the active marker frequency. If activated in
a non-preselected band,
Presel Center
does nothing.
Preselector center should be used to improve amplitude accuracy for
signals which fall into any one of the harmonic mixing bands. The
harmonic mixing bands Frequency Ranges are:

Presel Adjust
Agilent E4404B, E4405B, E4407B and E4408B only. Allows manual
adjustment of the preselector frequency to optimize its response on the
signal of interest.
By changing the
Presel Adjust
, the center of the preselector filter can be
moved in frequency. The signal of interest will appear to change in
amplitude with the frequency response of the preselector filter.
