65 FS1 Installation and Operation Manual — 40.1 Freeze Output
40.1 Freeze Output
This parameter tells the FS1 to freeze the current video frame on all outputs. This may
be useful either for testing or in case of loss of the input source.
Note: The freeze feature can be controlled not only by the front-panel and web
browser interface, but also by a GPI input. When a GPI input is causing the freeze
condition, the AUX lamp will be lit on the front-panel.
41.2 Video SG
This parameter determines the video test signal output from the FS1’s internal test
signal generator. The parameter is used with parameter 41.1 to determine the type of
video test signal output by the FS1.
41.3 Audio SG
This parameter determines the audio signal output from the FS1’s internal test signal
generator.
