number that app
ears on the display next to the red R inside a triangle when markers
areon. If all markers are off, the value returned will be the last value displayed.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

RF
Syntax
MARKER:REFERence:FREQuency?
Examples
MARKER:REFERence:FREQuency? might return 1.6830E+9.
MARKER:TYPe
This command specifies the marker type (either DELTa or ABSolute). An absolute
marker shows the frequency and amplitude at the location of the marker. A delta
marker shows the frequency and amplitude of the marker relative to the Reference
Marker. The Reference Marker shows the absolute frequency and amplitude,
regardless of this command. The marker amplitude measurements are in dBm for
absolute, or in dBc (dB below carrier amplitude) for delta.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

MARKER:TYPe {DELTa|ABSolute}
MARKER:TYPe?
Related Commands
MARKER:PEAK:STATE, MARKER:PEAK:MAXimum, RF:UNIts
Arguments
DELTa specifies to display the frequency and amplitude of the markers relative
to the Reference Marker. The relative amplitude is in dBc (dB below carrier
amplitude); the relative frequency is in Hz.
ABSolute specifies to display the actual frequency and amplitude of each marker.
The absolute amplitude is in user-set units; the absolute frequency is in Hz.
Examples
MARKER:TYPe DELta changes the marker type to delta.
MARKER:TYPe? might return ABSOLUTE.
