Operating the generator

This section describes basic operating procedures. There are four operational interfaces

for controlling the generator.

• Physical controls. Most of the generator’s features and functions are supported using

the front panel using the knobs and keys. Functions which are not supported using the

front panel include upgrading the firmware, creating and editing formats, creating and

editing images and reconfiguring the format and image knob lists.

• Command line. An ASCII command line interface, available through the RS-232 port,

allows you to send commands either interactively or as command files. All functions are

supported by the command line interface except upgrading firmware.

• Video Generator Manager (VGM). VGM is a Windows-based application that supports

most generator functions using a graphical user interface. When upgrading the

generator firmware, VGM must be used.

• GPIB Programmatic interface (optional). An IEEE-488 GPIB interface supports the

use of the 802 as a programmable video signal source in an automated test

evironment. All generator commands are supported through this interface.

Physical controls

The physical controls on the generator consists of the Format knob, Image knob, and eight

keys, arranged into four function groups: Image, Video Gate, Sync Gate, and Outputs. All

of the keys have built-in indicator lights. When illuminated, a key’s function is considered

on, or enabled.

Power switch

This rocker switch turns the power on and off. The power supply is auto switching and can

handle 110 or 220v.

Format knob

The Format knob is used to select a video signal format from a list of stored formats. A

format is a set of parameters that specifies the video and sync signal requirements of a

particular timing. Format parameters include timing, sync type, video type, display size,

and others. By turning the knob, you can scroll through a list of formats stored in

non-volatile memory. The list includes the factory default formats. The knob list can be

edited to add custom formats. If a format containing erroneous information is selected, the

generator turns off the outputs, and displays an error message.
