connect automatically and bypass the dialog. Otherwise, PGApp will bring the dialog up
normally for module selection.
In addition, the Connection dialog is also used to switch to a different instrument
configuration. Use the menu option “File->Choose PG…” to bring up the dialog. The
application will ask you if you wish to discard the current setup and data. Clicking “Yes”
allows PGApp to proceed and immediately connect to the new module. If you click
“No”, a Save System dialog will be brought up first to allow you to save your setup and
data. If you click “Cancel”, nothing is saved and no new connections are made.
4.5.2 System Window
Once connection has been made to an instrument’s modules, the main window with its
top-level System window is displayed. The System window (Figure 3) shows a graphic
representation of the pattern generator. A single module instrument shows the module
serial number, a text entry field to name/rename the instrument, and buttons to bring up
the two main configuration windows of PGApp: the Program Window and the Setup
Window (also a vestigial button to turn on and off the instrument that is no longer
functional). A multiple module instrument adds slave module outlines to the main
graphic, each labeled with a slave module serial number.
Figure 3 – System Window
In the legacy Tektronix PG application, the System Window had more functionality,
potentially showing multiple instruments and allowing the user to switch among them. In
PGApp, the System Window is static, and is mostly used to navigate to the Program and
Setup windows.
4.5.3 Setup Window
Clicking on the Setup button in the System window brings up the Setup window. The
Setup window is a tabbed window with four pages: Module Setup, Channel Setup, Probe
Setup, and Signals Setup. While most setup configuration can be done at any time,
channel configuration should be performed first before setting up the pattern generator
