Autoscale
Autoscale enables the vertical scale and range to be set automatically, which can make it easier
to keep the live signal(s) visible in the plot. Sometimes, when a measurement doesn't appear as
expected, setting Autoscale to Auto can solve the problem. When autoscale is off, the vertical
scale of the plot can be manually adjusted by a two-finger pinch gesture within the axis label
region of the plot. The range can be adjusted by a single-finger slide gesture within the axis
label region.
Show Secondary Level
In addition to the main spectral bars, the octave analyzer can also display the max or peak
value at each frequency above each associated spectral bar. Use this switch to turn the
secondary level display on or off.
Secondary Level Type
Use the segmented control to select whether to display the max or peak values at
each frequency above each associated spectral bar.
Draw Div Lines
When this switch is on, horizontal grid lines will be drawn in the display,
which divide the display into 20 equal divisions.
Frequency Units
This segmented control lets you choose whether to display frequencies in Hz or cpm (cycles per
minute).
Reference Curves
This segmented control lets you choose whether to display NC, RNC, or NR curves over the spectrum bar graph.
Cursor Options
Peak Track
The cursor may be configured to automatically move to the frequency of the peak value
within the current spectrum. This option allows the peak track function to be disabled,
or to track the maximum or minimum peak within the spectrum.
Peak Track Channel
When working with multiple channels in the Octave analyzer, this option lets you choose which
channel the peak track function will apply to (the channel whose spectral peak will be tracked
by the cursor).
Horizontal Bar
When working with multiple channels in the Octave analyzer, this option lets you show or hide
the horizontal bar. It also lets you choose which
channel the horizontal cursor bar will be associated with.
