Marker Y Axis Value (Remote Command Only)
Returns the marker Y Axis value in the current marker Y Axis unit.
The “result” of a marker is the value which is displayed on the second line of the Marker
Result block. To properly interpret the returned value the remote programmer must also
know what the analyzer's Y-Axis Unit is set to as described below.
A marker can have up to two results, only one of which is displayed or returned on a query,
as follows:
• Absolute result: every marker has an absolute result and it is simply:
— For Normal and Delta markers, the Y-axis value of the trace point the marker is
currently on.
The absolute result is displayed in the result block or returned on a query unless the
marker control mode is Delta.
• Relative result: if a marker's control mode is Delta, the relative result is displayed in
the result block or returned on a query. This is the difference between the Absolute
Result of a delta marker (expressed in dBm) to the Absolute Result of its reference
marker (expressed in dBm). The difference is expressed in dB.
Preset/Default Center of screen - Number of sweep points per default is 401(X
position scale goes from 0 to 400), so the default center position
is 200
State Saved No
Min 0
Max This Max value will clip to the value set for the number of
sweep points. Per default, this number is 401. The max value
that can be entered for the number of sweep points is 1001, so
the Max value that could be reached for this Marker X Axis
position is 1000.
