86 Chapter 6 Working with Test Sequences
Overview
When testing video displays, you typically select a format using the Format knob, and then
select an image using the Image knob. In a production environment, where there might be
a need to test several combinations of formats and images, you can create a test
sequence to automate the process of selecting formats and images. Test sequences
provide a way to progress through a pre-defined sequence of format and images, either
manually or automatically.
You can create test sequences using the command line interface, the internal sequence
editor or the Video Generator Manager (VGM) application. This section describes how to
create and run test sequences using the command line interface and internal sequence
editor. Please refer to the VGM online help for instructions on defining and running a test
sequence from VGM.
The following functions are provided:
• Create your own custom test sequences consisting of multiple steps. Each step
specifies the format and image to display as well as the duration of the step. You can
create multiple sequence files, which are stored in non-volatile memory.
• Program the 802R/BT generator to run in test-sequence mode on power-up. This mode
of operation is useful in a manufacturing test environment where the same test
procedure must be repeated on many identical displays. Multiple test sequences can
be stored in the generator and selected by the operator.
