Standard diagnostic testplans are shipped with each system.
There are two different testplans to test the system, from
functionality to internal connections, to connections on the
Test System Interface.
The first testplan, called the DGN, is used to verify both the
core system instrument operation and internal test paths. No
hardware is required to run this testplan. It verifies about
50% of the system functionality.
The second testplan, the "Customer Engineer Diagnostics"
testplan or simply CEDGN, is used to complete the test
coverage. This test requires external hardware, which is
packaged as a CEDGN kit, because it verifies the internal
connections out to the Test System Interface.
The tests are executed in the Agilent TestExec SL software
and the TS- 8989 system programming environment using
both standard and specialized test actions. The testplans
only cover standard instruments in the system. If there is a
special case where non- standard equipment are incorporated
into the system, tests for these equipment would have to be
added.
Before running the DGN or CEDGN testplans, instruments in
the system have to be added to the system.ust file. Testplans
can access and control instruments only if they have been
added into the system.ust file.
Standard instruments in the TS- 8989 are included in the
DGN and CEDGN testplans. A
