All component signals must use Input B:. To configure the B input:
1. Press the
Config
button.
2. Select INPUT and then press the
Enter
button.
3. Select INPUT B:.
4. Turn the knob or press the
Enter
button until the desired component signal is listed.
5. Press the
Clr Mnu
button to exit.
NOTE: In this manual S-video signals are not considered component signals. S-video
signals are treated like composite signals with regard to menu selections.
The graticule changes to accommodate the type of signal you selected. For example, 525 Beta signals
use an IRE graticule; however, MII and SMPTE signals use a voltage graticule.
When you select the B: input (by pressing the
Input
button) the
Display
button becomes active. At
first the Single LED is on and you see only the Y (or G) channel. Press the Display button once to
light Alternate and see all three components superimposed. Press the
Display
button a second time to
see the three components paraded side-by-side.
In Alternate or Parade mode, you can move the three parts separately. When you first enter either
alternate or parade mode, the
V Pos
knob moves all three components together. Pressing the
Position button cycles through each of the components and then back to all three. Adjusting the
vertical position of one of the components in Alternate mode has no effect on its position in Parade
mode.
Component signals can be seen in any of the three sweep rates, with the following restrictions:
•
In the 2F sweep rate, you can only view at the Y (or G) channel.
•
In parade mode, the sweep cannot be changed.
You can also see vectors of component signals but not GBR signals. The vector circle in component is
more simplified than the composite version because the phase angle does not have any real meaning.
When you view a vector and waveform together, you see only the Y channel of the waveform because
the B-Y and R-Y channels are represented in the vector.
