Scope of Type File
For a scope of type file, the scope acquires data and writes it to the file named
in the
FileName parameter in blocks of size WriteSize. The scope acquires the
first
N samples into the memory buffer. This memory buffer is of length
Number of Samples. The memory buffer writes data to the file in WriteSize
chunks. If the
AutoRestart check box is selected, the scope then starts over
again, overwriting the memory buffer. The additional data is appended to the
end of the existing file. If the
AutoRestart box is not selected, the scope collects
data only up to the number of samples, and then stops. The number of samples
N to log after triggering an event is equal to the value you entered in the
Number of Samples parameter. If you stop, then start the scope again, the
data in the file is overwritten with the new data.
Select the type of event in the Block Parameters: Scope (xPC Target) dialog box
by setting
Trigger Mode to Signal Triggering, Software Triggering, or
Scope Triggering.

host, use the drop-down list next to the Add Scope
button to select
