VCO Centre Frequency
Normally, the output is locked to the video reference - if present - and of the same standard as the video,
or to the input video itself. If there is no signal or reference connected then the output will free run at the
nominal centre frequency of the on board clock generator. This centre frequency can be adjusted under
the
CALIB
:
CntrFreq
menu, but this should not normally be necessary in the field.
It is possible to force the unit into its free-run mode using the
ENG’ING
:
Free-run
menu. This is an
unusual requirement and so is a setting that appears on the top level banner when set.

Memory Size
The amount of SDRAM fitted on the baseboard can be checked in the read only menu
STATUS
:
Mem Size
. Some module functions, such as the Field/Frame Delay option, are memory size
dependent. Currently, modules are available with two different memory configurations:

Supported Features
24MBytes
Basic – with limited Field/Frame Delay functionality
96MBytes
Required for full Field/Frame Delay support

Display Sleep
Since, for the vast majority of its life, a module will operate behind the front panel of a rack frame, the
display on the local front panel will not be visible so it will go to sleep after a certain time. This timeout
delay can be changed on the
ENG’ING
:
Sleep
menu to be anything between 0 and 30 minutes; 0
minutes means that it will stay on indefinitely. The sleep timeout always counts from the last front panel
button push. The default time is 5 minutes.
The panel can also be forced into its sleep mode by moving up a level from the Top Level menu, which
displays the module type.
To get the display to come on again simply press one of the buttons and the menus will start again at the
Top Level.
3.2.19
Display Brightness
The brightness of the front panel display can be adjusted on the
ENG’ING
:
LEDLevel
menu.
