3 Short-Range Comms & IoT Mode
3.2 Modulation Analysis Measurement
Example
:CALC:EVM:MARK2:REF 4
:CALC:EVM:MARK2:REF?
Notes This command causes the marker specified with the subopcode to become selected
Range (for SCPI command): 1 to 12. If the range is exceeded the value is clipped
A marker cannot be relative to itself so that choice is not available, and if sent from SCPI generates
error -221: “Settings conflict; marker cannot be relative to itself”
When queried a single value is returned (the specified marker numbers relative marker)
Couplings The act of specifying the selected marker’s reference marker makes the selected marker a Delta marker
If the reference marker is off it is turned on in Fixed or Normal mode at the delta marker location
Preset The preset default “Relative To” marker (reference marker) is the next higher numbered marker (current
marker +1). For example, if marker 2 is selected, then its default reference marker is marker 3. The
exception is marker 12, which has a default reference of marker 1
Set to the defaults by using Restore Mode Defaults. This is not reset by Marker Off, All Markers Off, or a
Preset
State Saved Saved in instrument state. Not affected by Marker Off and hence not affected by Preset or power cycle

Marker Window
This control enables you to assign the specified marker to the designated trace.
Remote Command
:CALCulate:EVM:MARKer[1]|2|...|12:WINDow <int>
:CALCulate:EVM:MARKer[1]|2|...|12:WINDow?
Example
:CALC:EVM:MARK:WIND 2
sets the first marker’s trace to window 2
:CALC:EVM:MARK:WIND?
query the first marker’s trace
Notes Assigns the specified marker to the designated window
