Theory of Operation 8
16901A Logic Analysis System Service Guide 99
Because the service should always be running regardless of
whether any user is logged onto the system, the logic
analyzer should always be responsive to remote connection
requests from other machines. The Touch Off button should
also always function.
When the GUI application is launched by a logged on user,
the application (by default) will attempt to connect to local
hardware and go "online". If the service is not started, the
application should either wait for the service to start (newer
software revisions) or generate a message box indicating the
service needs to be started (older software revisions). If the
drivers are not loaded, the GUI application will start in
offline mode.
Once the GUI application is running, the user can go online
with local hardware or the hardware in any other Agilent
168x/169x/168xx/1690x logic analyzer running the same
version of the logic analyzer software. The remote machine
must be available on the network.
Product install
The product install (SetupLAxxxx.exe) performs the
following:
• Install the logic analyzer- specific files to the local hard
drive.
• Register the application with the operating system
(various registry settings are applied including COM
registration).
• Create start menu/desktop shortcuts.
• Install device drivers.
• Install and start the service.
• Check frame boot- EEPROMs (non- volatile ROMs) and
verify they are up- to- date. Reloads the boot- EEPROMs if
necessary.
