Starting the Oscilloscope
Starting the Oscilloscope involves following steps:
1. Opening an APOSS program in an APOSS Window.
2. Connecting to the controller.
3. If the TESTSETP Oscilloscope is being used, then before starting the Oscilloscope, execute the
APOSS program which creates the TESTSETP array.
4. Starting the selected Oscilloscope.
Opening an APOSS program
Begin by opening the APOSS program (.m) corresponding to the program currently loaded or executing in
the controller. This will open a normal APOSS Window. Note that it is not strictly necessary to open the
corresponding program. Any program, or even a new program, can be opened. For example, the user may
not have the actual program readily available. However, opening the correct program can make the
diagnostics effort easier since the user can refer to the program while trying to understand the results of
the test.
Connecting to the controller
In the APOSS Window, connect to the appropriate controller. Use any of the available methods (e.g. the
[Esc] key to connect to the default controller, the Development → Select Controller menu command, the
Connect toolbar button, etc.).
Before using the TESTSETP Oscilloscope
The TESTSETP Oscilloscope expects a TESTSETP array to exist prior to the Oscilloscope being started. The
Oscilloscope will automatically read this array when it is started. Hence, the user must first execute an
APOSS program that records the desired data using the various TESTSET commands. This program can be
started in the normal way by using Development → Execute [F5].
Starting the Oscilloscope
Each of the different Oscilloscope versions can be
started from the Tools menu or by clicking on one of
the Oscilloscope toolbar buttons. The Oscilloscope
will also be started if a previously saved
"oscilloscope file" is re-opened. Oscilloscope files are
described below.
The Oscilloscope will automatically be connected to the controller that was connected in the APOSS Window.
Note that if a controller was not already connected in the APOSS Window, then starting the Oscilloscope will
cause the default controller to be connected.
An Oscilloscope window similar to the following will
be opened. The connected controller can be seen at
the far right side of the "Curve Selection List". The
green box in the "Status" column in this example
indicates that the controller is connected, is
executing a program, and is not in an error state.
An Oscilloscope can also be started by opening an Oscilloscope file that was previously saved from an
Oscilloscope. This is done simply by opening the Oscilloscope ".zbo" file using any of the normal methods
for opening files. A Free Run Oscilloscope window similar to the following will be opened.
