Configuring the Host Scope Viewer
You can customize your host scope viewer. This section assumes that
you have added a host scope to your target application, started the host
scope viewer, and added signals
Integrator1 and Signal Ge nera tor (see
“Creating Scopes” on page 3-17 a nd “Adding Signals to Scopes” on page 3-24).
These viewer settings are per scope.
In the xPC Target Host Scope Viewer, right-click anywhere in the axis area of
the viewer.
A context menu is displayed. This context menu contains options for the
following:

variable is
application_name_scn_data, and the default name for the time
variable is
application_name_scn_time where n is the scope number.
Select Export Scope Data to export scope data to the MATLAB interface.
Acquiring Signal Data into Multiple, Dynamically Named Files

You can acquire signal data into multiple, dynamically named files on the
target PC. For example, you can acquir edataintomultiplefilestoexamine
