Marker Function
Marker Function
The Marker Function key opens up a menu of softkeys that allow you to control the Marker
Functions of the instrument. Marker Functions perform post-processing operations on marker
data. 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.
Unlike regular markers, marker 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.

Remote Command
:CALCulate:MARKer[1]|2|...12:FUNCtion NOISe | BPOWer | BDENsity | OFF
:CALCulate:MARKer[1]|2|...12:FUNCtion?
Notes
Sending this command selects the sub-opcoded marker
The marker function result is queried in the same way as the Marker Result, as outlined in the
Marker section, with the CALC:MARK:Y? command.
Dependencies
Fixed markers: It is not possible to change the Band Function for a Fixed marker; so all of the
Band Function keys are grayed out for a Fixed marker.
If a marker function was already on when the marker became Fixed, then the selected Band
Function is shown but cannot be changed. Therefore, you cannot directly set the X or Y value of
a Fixed marker that has a marker function turned on. To turn off the function, turn off the
marker.
Preset
OFF
State Saved
The band function for each marker is saved in instrument state
Backwards Compatibility
Notes
The introduction of adjustable-width Band Functions in the X-Series fundamentally changes the
way Band Power markers are controlled. See the section entitled
below for a complete discussion of programming Band Functions in a
backwards compatible fashion.
