Scale Type
Log Lin
Agilent ESA-E Series only (E4401B, E4402B, E4404B, E4405B and
E4407B). Scales the horizontal (x-axis or frequency) graticule divisions
logarithmically when
Scale Type (Log) is selected. When Scale Type (Lin)
is selected, the horizontal divisions are linearly scaled.
In
Scale Type (Log), the number of sweep points is limited to a multiple
of the number of sweep segments. For example, if you select 308 points
when 3 segments are required to create a logarithmic display, the
points will be set at 306 points. The span determines the minimum
number of sweep points. Pressing
Preset (when Preset Type is set to
Factory) sets Scale Type to Lin.
NOTE Sweep time is auto-coupled when Scale Type (Log) is selected.
NOTE Marker Span Pair, Frequency Offset, Input Mixer (Ext), Segmented (On),
Signal Track (On), and Demod View (On), are not available when Scale
Type (Log) is selected.
NOTE FREQUENCY, Scale Type (Log) is not available when Frequency Offset,
Segmented (On), Input Mixer (Ext), Zero Span, Signal Track (On) is selected.
