3 VMA Mode

3.1 Digital Demod Measurement

Notes The selected marker is remembered even when not in the Marker menu and is used if a search is done

or a Band Function is turned on, or for Continuous Peak

Preset Marker 1

State Saved The number of the selected marker is saved in instrument state

3.1.8.2 Settings

The controls on this tab include the Marker active function and a radio button

selection of the marker control mode (Normal, Delta, Fixed or Off) for the selected

marker, as well as additional functions that help you use markers.

Marker X

Enables you to set or read back the X Axis value of the selected marker in the current

X Axis Scale unit. If the marker mode is off, the SCPI command has no affect other

than to cause the marker to become selected. Note that the X value can change if

the marker is moved to a trace with a different domain.

The Marker X position is absolute if the marker mode is Normal or Fixed. If the mode

is Delta, then the X position is relative to the reference marker. The valid X positions

are the actual data points in the trace; the marker cannot be located between

points. If a SCPI command attempts to place the marker between two points, the X

value snaps to the closest point.

Remote

Command

:CALCulate:DDEMod:MARKer[1]|2|…|12:X <real>

:CALCulate:DDEMod:MARKer[1]|2|…|12:X?

Example

:CALC:DDEMod:MARK:X 0.325

:CALC:DDEMod:MARK:X?

Notes Does not exceed the bounds of the data unless it is Fixed. If you attempt to set it to a value outside the

bounds, it is clipped at the closest limit and Error -222 Data Out of Range is generated

If suffix is sent, it must match the X units for the trace the marker is on. Otherwise, error -138, "Suffix

not allowed" is generated

If you try to read or set the position of a Delta marker, remember that the position is in relative units

Couplings Coupling of Delta and Reference Markers

Preset None until marker is turned on

State Saved Yes
