Product Overview

Formats

A format is a set of specifications that describe the video signal required by a particular type of display.

The 801G series are low-cost portable video signal generators designed for basic testing and alignment of various types of raster-scanned displays. This manual covers the 801GC, 801GF and 801GX mod- els. Information that mentions the “801G*” applies to all three models.

The generator is shipped with over 100 signal for- mats in place for driving a variety of industry-stan- dard displays. Formats for other displays can be added using the built-in graphics user interface editor or a personal computer or terminal via the built-in RS-232 and IEEE-448 interfaces.

Formats are stored in a non-volatile memory. This memory has room for up to 300 formats. Permanent copies of industry-standard formats are stored (along with the generator's operating code) in EPROM and can be copied into format memory and modified as required.

Images

The 801G* features over 50 test images that allow a

 

wide variety of display criteria to be checked. The

 

generator has an image loop feature that can be used

 

for monitor burn-in or at trade shows to display a

 

series of images over and over. User defined cus-

 

tom test images can also be created and saved in

 

non-volatile memory.

Controls

The number of controls on the 801G* has been mini-

 

mized to insure simple operation. Two knobs and 8

 

lighted push-buttons provide complete control of the

 

generator. One knob selects the video signal format.

 

A second selects the test image. Three push-buttons

 

gate the individual video components on and off.

 

Another three push-buttons select any of three avail-

 

able synchronizing signals. A seventh button allows

 

all of the outputs of the generator to be turned on

 

or off with a single key stoke. Finally, an image

 

stepping button is provided that calls up alternate

 

versions of some images.
