• Running a user defined test sequence. Each step
in a test sequence combines one format and
one test image. The operator can then go for-
ward and backwards through the steps using
a single knob. The 801G* can be programmed
so that it automatically enters a test sequence
mode on power-up. This mode of operation is
suitable for a test position in a manufacturing
environment where the same series of tests and
adjustments need to be repeated on many iden-
tical displays. There is less likelihood that an
operator on the line will select the wrong for-
mat or skip an important alignment procedure.
It is also possible to set the 801G* to continu-
ously cycle through the steps in a test sequence.
Information on creating and running test se-
quences is contained in the “Programming”
chapter.
• Programming mode. Formats, the format list,
custom images, the image list and test sequences
can be created and edited using the built-in
Graphics User Interface (GUI). In order to use
the GUI, a display that is compatible with any
stored format and has at least 640 active pix-
els and 480 active lines needs to be connected
to the 801G*. The contents of the format, cus-
tom test image or test sequence are shown on
the display. The 801G*’s knobs and buttons are
used to select and modify the displayed pa-
rameters. The current button functions are
labeled at the bottom of the GUI screen. No
other hardware, other than the display, needs
to be connected to the 801GX.
Information on using the GUI editors is in the
“Programming” chapter.
