Measurement
This function allows you to get precise real time YRGB measurements of any point or area within your incom-
ing signal. To toggle this feature on/off simply press the function key you have assigned to the Measurement
function to display a movable crosshair onscreen. With the Measurement function on you can use the H
POS (PHASE) and V POS (CHROMA) rotary knobs to position your crosshair over the point within your
source that you would like to measure. To reset the vertical or horizontal position of your crosshair back to
center simply press down on the corresponding rotary knob. You may also use the REF POS (BRIGHT) rota-
ry knob to select the size of the sampling area for the measurement data (from a single pixel to a much larger
area where the values will be an average of all pixels within your defined sample area). As you move the
crosshair your Measurement data will update in real time. The Measurement function is available in a 10 bit
mode or 8 bit mode and will provide you with the following data in real time:
Line and Sample (Identifies position of your crosshair)
Y (Luminance as an absolute value between 0-255 for 8 bit and 0-1023 for 10 bit)
Y% (Luminance level expressed as percentage)
R% (Red level expressed as percentage)
G% (Green level expressed as percentage)
B% (Blue level expressed as percentage)
R (Red level as an absolute value between 0-255 for 8 bit and 0-1023 for 10 bit)
G (Green level as an absolute value between 0-255 for 8 bit and 0-1023 for 10 bit)
B (Blue level as an absolute value between 0-255 for 8 bit and 0-1023 for 10 bit)
You can also press the REF POS rotary knob (F.D. / BRIGHT / Ref Pos.) to set a reference position on-
screen. Once your reference position is set it will be indicated on screen by a separate crosshair and you will
be able to move the active crosshair to obtain a real time readout of your current and reference positions as
well as a separate readout of the precise difference between current and reference locations. Please note
that your reference position is both a spatial and temporal reference meaning that the values indicated on
screen for the reference are for that point on screen at the moment you set the reference.
Pressing the F Stop (Contrast) rotary knob button allows you to set your current crosshair position as an F-
Stop Reference and view differences between this current position and your reference position as an F-Stop
value. The F-Stop reference feature is independent of the REF POS feature. The F-Stop reference value will
always be based on the levels of your current active crosshair position at the precise moment when the Con-
trast knob is pressed.
The crosshair color will follow the color selected for markers from the
Marker Menu
. To change the color of
the Measurement function’s crosshair change the Marker color.
