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.

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.

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.

MASK:COPy:SO
Urce
This command specifies the mask that is to be copied to a user-defined custom
mask. The specified mask is not copied until after the
MASK:COPy:USER
command is ex
ecuted. Note that in addition to a standard mask,
LIMit, US ER
and NONe can also be specified.
NOTE. The only argument enumerations available for the MDO3000 series
models are
CUSTom | LIMit | NONe | USER
.
A series of examples showing how to use mask commands for typical tasks
is included in an appendix. (See page E-1, Mask/Limit Command Sequence
Examples.)
Conditions
This command requires a DPO4LMT application module for 4000 series models,
and an MDO3LMT application module for MDO3000 series models.
