Arguments
OFF or 0 turns the manual markers off.
ON or 1 turns the manual markers on.
Examples
MARKER:MANual 1 turns on the manual markers.
MARKER:MANual? might return 0, indicating that the manual markers are turned
off.
MARKER:M<x>:AMPLitude:ABSolute? (Query Only)
This query returns the actual amplitude (vertical) value of either of the two
manual markers that are available for frequency domain traces, in user-set units.
M<x> can be either M1, which specifies manual marker a,orM2,whichspecifies
manual marker b.(UseRF:UNIts to specify the units.)
Conditions

MARKER:M<x>:
AMPLitude:DELTa? (Query Only)
This query returns the delta amplitude (vertical) value of either of the two
manual markers that are available for frequency domain traces, in relationtothe
Reference Ma
rker. M<x> can be either M1, which specifies manual marker a,or
M2, which specifies manual marker b.
NOTE. Querying the delta of M1 will always return 0, because M1 is always the
Reference Marker when manual markers are turned on.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Examples
MARKER:M2:AMPLitude:DELTa? might return –5.0E+00, indicating that marker
b is –5 dBc below marker a, which is also the Reference Marker.
MARKER:M<x>:FREQuency:ABSolute
This command specifies the actual frequency (horizontal) value of either ofthe
two manual markers that are available for frequency domain traces. M<x> can
be either M1, which specifies manual marker a, or M2, which specifies manual
marker b.
NOTE. Markers cannot be placed outside the frequency range defined by
RF:STARt and RF:STOP.

Arguments
<NR3> isafloa
ting point value that indicates the actual frequency of either of the
two manual markers.
Examples
MARKER:M1:FREQuency:ABSolute 1.50E+9 sets the absolute frequency
value of manual marker a to 1.5 GHz.
MARKER:M2:FREQuency:ABSolute? might return 1.50E+9, indicating that the
absolute frequency value of manual marker b has been set to 1.5 GHz.
MARKER:M<x>:FREQuency:DELTa? (Query Only)
This query returns the delta frequency (horizontal) value of either of the two
manual markers that are available for frequency domain traces, in relationtothe
Reference Marker. M<x> can be either M1, which specifies manual marker a,or
M2, which specifies manual marker b.
The manual marker readouts use the units specified with the command RF:UNIts.
NOTE. Querying the delta of M1 will always return 0, because M1 is always the
Reference Marker when manual markers are turned on.
