Command groups
Display control command group
Display commands can be found in this section as well as the sections of related
components. These commands control general oscilloscope settings, such a s the
intensity of the graticule, stacked or overlay display mode, and the fastacq color
palette. Display commands also control how and where w aveforms are shown,
their posit
ion on screen, and zoom settings applied to the view. For example,
display commands c an turn on or off the display of channels or set the selected
source.
Some actions can create a new view which can have its own settings. For example,
adding a histogram w ill create a new view where the Histogram plot is displayed.
Each view acts as a separate window within the oscilloscope application and can
be rearranged or annotated as desired.
A WaveView is the primary view used for viewing inputs and time-domain
signals. Buses, non-FFT maths, refs, analog and digital channels, and time-trends
are displayed in the WaveView.
A PlotView is used for viewing m easurement results and other plotted data.
Histograms, eye diagrams, XY/XYZ plots, FFTs, and other plots are shown in
individual PlotViews.
Each of these views can h ave separate settings, zoom, cursors, and annotations.
Display commands which are view specifichaveaviewparameterin
the programmable interface, such as DISPLAY:WAVEView<x>: ... or
DISPLAY:PLOTView<x>: ... Selected source can also be specified on a per-view
basis. The overall selected source is determined by the selected vie w and the
selected source w ithin that view.
PlotViews and WaveViews have some differences in command syntax due to
differences in view functionality. For example, WaveViews and PlotViews have
a different zoom model. The commands for specifying the zoom reflects these
differences, and different command syntax is available depending on the view.
