<m> Marker
Parameters:
<Trace> Trace number the marker is assigned to.
Example: CALC:DELT2:TRAC 2
Positions delta marker 2 on trace 2.
CALCulate<n>:DELTamarker<m>:X <Position>
This command moves a delta marker to a particular coordinate on the x-axis.
If necessary, the command activates the delta marker and positions a reference
marker to the peak power.
Suffix:
<n>
.
Window
<m> Marker
Parameters:
<Position> The position is relative to the reference marker.
The unit is Hz (offset frequency).
A query returns the absolute position of the delta marker.
Range:
The value range depends on the current measure-
ment range.
Example: CALC:DELT:X?
Outputs the absolute frequency/time of delta marker 1.
CALCulate<n>:DELTamarker<m>:Y?
This command queries the relative position of a delta marker on the y-axis.
If necessary, the command activates the delta marker first.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.
