Image Knob in Normal Mode

The format knob is normally used to select a signal format. A format is a set of parameters that specify the video and sync signal requirements of a par- ticular display. Format parameters include timing, sync type, video type, display size, etc. By turning the knob, you can scroll through a list of formats stored in non-volatile memory. The list includes many factory default formats. You can edit the list as well as add formats that you create. A new format is loaded with each click of the knob. Loading a for- mat redraws the current test image and updates the LCD. If you select a format containing erroneous information, the outputs of the generator are auto- matically turned off and an error message is dis- played. The knob performs other functions when the editors are being used.

The format knob performs other functions when the 801G* is operated in the either the test sequence or GUI programming modes. Please see the “Program- ming” chapter for detailed information on operat- ing the 801G* in the other modes.

The image knob is normally used to select a test image. The exact behavior of the knob depends upon the status of the “Image” push-button. Turning the knob when the button is not lit scrolls through the main list of test images. The knob performs other functions when the editors are being used.

❖Not all images are supported by all signal for- mats. Some images in the main image list may be skipped while certain formats are present. For example, the ColorBar image will be skipped whenever a monochrome format is present. If the currently selected image cannot be drawn given a newly selected format, the Outline im- age is automatically drawn after the new format has finished loading.
