"Monochrome"
The waveform is displayed in monochrome colors, which depend on
the color of the selected source channel. Black corresponds to the
low-level values while the channel color indicates for high ones.
Remote command:
SPECtrum:DIAGram:COLor:SCHeme:SPECtrogram
SPECtrum:DIAGram:COLor:SCHeme:FDOMain
Magnitude Mode
Enables the magnitude-dependent coloring of the waveform. The higher the level, the
higher the color in the color scale.
When the "Magnitude Mode" is disabled, then the color depends on the frequency of
occurrence of a value.
Remote command:
SPECtrum:DIAGram:COLor:MAGNitude:MODE
Find Threshold
Sets the level automatically to
0.5 * (MaxPeak – MinPeak)
. The
MinPeak
is set in the
noise floor and the
MaxPeak
is the highest point of the waveform.
Maximum
Sets the level that is used as a maximum for the color scale selected with
All level values higher than the maximum are displayed with the maximum color.
Remote command:
SPECtrum:DIAGram:COLor:MAXimum[:LEVel]
Minimum
Sets the level that is used as a minimum of the color scale selected with
All level values lower than the minimum are displayed with the minimum color.
Remote command:
SPECtrum:DIAGram:COLor:MINimum[:LEVel]

XY-Diagram
XY-diagrams combine the voltage levels of two waveforms in one diagram. They use
the amplitude of a second waveform as the x-axis, rather than a timebase. Thus, you
can measure phase shift, for example. With harmonically related signals, the resulting
XY-diagrams are Lissajous patterns. XY-diagrams can also be used to display the IQ
representation of a signal.
Together with the XY-diagram, the time diagrams of the source signals are displayed in
separate grids. It is also possible to define two source signals in y-direction for compar-
ison.
