Special TestsGenerating Pseudo Random Noise
When the generator is connected to a device that supports the Quantum Data pseudo random noise
standard, press Test > PR Noise to output the noise pattern as a static image. Depending on how the
device is designed, it may compare the pattern output by the generator with an identical pattern,
created internally, to detect errors in the cable and in the device itself.
About VGM
Video Generator Manager (VGM) is a Windows-based application for creating and editing formats and
test sequences. As many as 132 formats and one test sequence can be stored in the generator.
VGM was originally created for use with Quantum Data 80x video generators. The 700A-Series
generators support only some VGM features. For information about using VGM, see the VGM help file.
