3.9 Spectral Flatness Measurement
If the trace the marker is on a 2-dimensional domain, then the points are numbered
in the following way:
Starting at the minimum X and Z position, this point is numbered 0. Each time you
increment the point number, increment the X value to the next available value.
When X reaches the maximum X position, then reset X to the minimum and
increment the Z value. Then continue incrementing the X position in the same
manner as before.
Note that for symbol tables, which have no axes, incrementing the X position in
points moves the marker consecutively through all table entries.

Command
:CALCulate:FLATness:MARKer[1]|2|...|12[:X]:POSition <real>
:CALCulate:FLATness:MARKer[1]|2|...|12[:X]:POSition?
Example
:CALC:FLATness:MARK:POS 25
:CALC:FLATness:MARK:POS?
Notes When a marker mode is changed from off to any other mode, the X position is set to mid-screen.
Preset None until marker is turned on.
State Saved Yes

Coupling of Delta and Reference markers
The following coupling rules apply from the front panel and also if the equivalent
SCPI commands are sent.
Pressing Delta causes the selected marker to become a delta marker if it is not
already. Also, the selected marker's reference is affected as follows:
–
If the reference marker was off, it is turned on as a Normal marker.
–
The reference marker is moved to the trace of the selected marker and set to the
same position as the selected marker.
–
If the delta marker has a marker function turned on, the reference marker takes
on the same function (with the same band limits).
