Setup menu Force centre no
Mode menu Aspect ratio off
Mode menu Centre off
When the
ellipse centering is Off and aspect ratio MODE is Off the position and the H and V size of the
ellipse lines can be positioned independently.
Size The left shaft encoder is used to adjust the height of the ellipse , and the right shaft encoder is
used to adjust the width of the ellipse .
Position The left shaft encoder is used to adjust the vertical position of the ellipse , i.e. move the ellipse
up or down, and the right shaft encoder is used to adjust the horizontal position of the ellipse ,
i.e. move the ellipse left or right.
3.8.3.6. Controlling the Ellipse Size and Position (Ellipse not centred, Aspect Ratio On)
Setup menu Force centre
No
Mode menu Aspect ratio 1:1 4:3 14:9 16:9 1.67:1 1.85:1 2.35:1
Mode menu Centre off
When the
ellipse centering is Off and aspect ratio mode is On the position and overall size of the ellipse
can be adjusted proportionately about the centre of the ellipse based upon the aspect ratio selected.
Size Either of the shaft encoders can be used to adjust the size of the ellipse around its centre, while
maintaining the selected aspect ratio for the H and V axes.
Position The left shaft encoder is used to adjust the vertical position of the ellipse, i.e. move the ellipse
up or down and the right shaft encoder is used to adjust the horizontal position of the ellipse ,
i.e. move the ellipse left or right.
3.9. LOADING FACTORY PRESETS
The FACT PRESET button is used to recall the most recently used factory preset . Turn one of the shaft
encoder knobs to cycle through the available factory presets . The name of the selected preset will be
shown on the front panel display, and the selected collection of object settings will be loaded into to the
Graticule Generator. The
PRESET ACTIVE LED will illuminate when one of the Factory presets is loaded.
The factory presets available at the time of printing are shown in Chapter 7. In the front panel descriptions
of the factory presets CA refers to clean aperture and PA refers to production aperture.
3.10. WORKING WITH THE USER PRESETS
The Graticule Generator has ten memory locations to store user defined presets. Each preset contains a
collection of object parameters that define what objects are on, and the
OBJECT MODES AND CTRL SEL
settings for the objects. There are ten user preset locations for each video standard. Each of the user
preset locations can be write-protected, or can be left unlocked, so users can save their favourite settings.
When the Graticule Generator is reset to its factory default condition, the ten user preset locations are
filled with ten of the factory presets .
