4.2.2 Systems configuration

The GV-998 TV pattern generator enables configuring a large variety of
parameters. So that the most common configurations may be selected without having
to individually modify parameters, the instrument will store up to 32 configurations (00
to 31) in its memory.
The different parameters which may be modified have been grouped into four
configuration menus:
ANALOG
MPEG2
TXT-VPS
SYNC-LOGO-SCART
To view the parameters relative to each menu in the display and thus verify the
configuration in use and/or modify it, simply press the selection key of the
corresponding menu [3], [4] or [5]. Whenever the key [3] is pressed, it changes
alternatively from ANALOG to MPEG. It is indicated with the corresponding LED.
Once the configuration menu you seek to consult or whose parameter you
intend to change appears in the display, you can progressively select the different
parameters by turning the rotary selector [6]. The selected parameter will appear
shadowed.
To activate a parameter and thereby change its configuration, once selected
(when it is shadowed), press the rotary selector, and the parameter will be underlined
(activated), on turning the rotary selector [6] the various possible options for that
parameter will appear. Pressing on the selector again re-establishes the selection
mode. The changes produced in the display directly affect the information present at
the generator output, though they do not alter the previously stored configurations,
therefore the modified modifications will be lost on switching off the generator.
