Marker Frequency | Time
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency | Time" on page 309 on the Settings tab.
Band Function
Band Functions are Marker Functions that allow you to define a band of frequencies
around the marker. The band defines the region of data used for the numerical
calculations. These marker functions also allow you to perform mathematical
calculations on trace and marker data and report the results of these calculations in
place of the normal marker result.
NOTE
Unlike regular markers, Band Function markers are not placed directly on the
trace. They are placed at a location which is relative to the result of the function
calculation.
If any of the band adjust SCPI commands (including the BAND:SPAN command and
the legacy compatibility commands documented under "Band Function Backwards
Compatibility" on page 346) are sent while the marker function is off, they are
accepted and the value stored. If sent while the marker is Off, they are accepted and
ignored.
