block. To properly interpret the returned value, you must also know how the
instrument’s Y-Axis Unit is set, as described below.
A marker can have up to two results, only one of which is displayed or returned in a
query, as follows:
–
Absolute Result: every marker has an Absolute Result. For POSition 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 as 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 in a query. This is the ratio of the
Absolute Result of a delta marker to the Absolute Result of its reference marker.
The ratio is expressed in dB

Command
:CALCulate:WAVeform:MARKer[1]|2|…|12:Y?
Example
:CALC:WAV:MARK11:Y?
Notes When the marker is on, IQ waveform returns I and Q values
Case #1 - Trace RF, I or Q: returns a single double value
>:CALC:WAV:MARK1:Y?
-2.402406506109E+001
Case #2 - Trace IQ: returns a double array of two values, the first is I, and the second is Q
>:CALC:WAV:MARK1:Y?
-3.006944493834E-003,+9.9870666467354E-004
The IQ selection is for backwards compatibility purposes. For new designs, use the I and/or Q selection
instead
You must be in a Mode that includes the Waveform measurement to use this command. Use :INSTru-

Preset Result depends on the marker setup and signal source

Marker Mode
Sets the marker control mode to POSition, DELTa, or OFF. All interactions and
dependencies detailed under the control description are enforced when the remote
command is sent. If the selected marker is OFF, pressing Marker sets it to POSition
(Normal) and places it at the center of the screen on the trace determined by the
