6-10 Chapter 6: Programming
Model 801GC, 801GF & 801GX¥Rev. A
meric parameter is selected, an underscore cursor is
placed below a digit in the number. The “Cursor”
buttons move the digit cursor and the bottom knob
changes the selected digit.
In many cases, entering a new value of one param-
eter will affect the values of other parameters as
well. The editor automaticall updates all related
parameters when you enter a new value.
The upper left corner shows the name and memory
location number of the selected format. When you
first use the editor, this information will be for for-
mat that is being used to drive the display. You
select the format you wish to edit by first selecting
location number parameter. Rotating the bottom knob
will take you through all of the formats stored in
teh 801G*. You create new formats by editing an
existing format and saving your work using a new
name and location.
❖ The location number is only used by the format
editor. The format knob directory and test se-
quences all use just the format name when se-
lecting formats from memory.
The unit of measure used for timing entries is also
shown in the upper left corner. You have two choices
for the units of measure. You can enter in units of
real “Time” (µSec and mSec) or in “Machine” units
(pixels and lines). You should use machine units for
precise control of your formats. The 801G* inter-
nally rounds off real time entries to match the near-
est machine unit of time. A single pixel period is
the basic unit of measure for all horizontal timing
parameters. All horizontal real time entries will be
rounded to an integer multiple of the pixel clock
period. A single horizontal period is the basic unit
of measure for all vertical timing parameters. All
vertical real time entries will be rounded to an in-
teger multiple of the horizontal period. You can
update your real time entries to their actual rounded
values by having the calculate function on and se-
lecting machine units of measure.
