Models 9590 & HD9590 Graticule Generator Manual
•
The standards 1080I/60 and 1080P/30SF are the same as far as the Graticule Generator is
concerned. When the video input is in either of these standards the Graticule generator will display
the standard as 1080I/60
•
The standards 1080I/50 and 1080P/25SF are the same as far as the Graticule Generator is
concerned. When the video input is in either of these standards the Graticule generator will display the
standard as 1080I/50
•
On certain earlier revisions of the High Definition Graticule Generator hardware it is necessary to
select whether the video clock rate is 1/1 or 1/1.001. (See section 3.2.12) On these units the Video
Freq menu item must be correctly selected in order for Auto Video Standard Detection to work
correctly. For example on these early units the HD9590 can automatically switch between 1080i/59.94
and 1080p/23.98sF because the video frequency divider is set to 1/1.001 in both cases. However, it
can not switch between 1080i/59.94 and 1080i/50 because the video frequency divider is different for
these two standards.
•
Auto Video Standard Detection cannot distinguish between 1035I/60 and 1080I/60. The light will not
blink if the Graticule Generator is in 1035I/60 or 1080I/60 mode and the other standard is coming in
the input. If 1035I/60 video is on the input the Graticule Generator will detect it as 1080i/60 and output
a 1080i/60 formatted video signal. The only way to force 1035I/60 mode is to select it manually from
the Video Std. Menu. Since there is no LED to indicate 1035i/60 mode, no LED will blink if the HD9590
is in 1035i/60 and another video standard is placed on the input.
3.2.12. Selecting the Video Field Rate (HD9590)
Vid Freq =
1/1.001
On certain earlier revisions of the High Definition Graticule Generator hardware it is necessary to select
the video frame rate manually using this menu item. On later versions of the hardware that autodetect the
frame rate this menu item will not be present.
Select 1/1.001 when using high definition video with a frame rate of 23.976, 29.97 or 59.94 frames per
second.
Select 1/1 when using high definition video with a frame rate of 24, 30 or 60 frames per second.
3.3. CONTROLLING THE INDIVIDUAL OBJECTS
The Graticule Generator has separate controls for each of its seven objects (grid, mask, box1, box2,
cursor1, cursor2, and circle). To turn on the object press the corresponding button. To select the second
object of a particular type (box2 or cursor2) press the corresponding button a second time. The selected
object will blink momentarily (if the OBJ BLINK item on the SETUP menu is enabled), and will be
automatically turned on. The LED above the button will come on indicating that the object is selected. To
turn off the object, press the ON/OFF button when the LED is illuminated. All objects will be automatically
de-selected after two minutes of inactivity on the front panel. Individual objects will also be deselected
when another object is selected.
