2.1 General
This unit is installed in the LV 5800 (MULTI MONITOR) or LV 7800 (MULTI RASTERIZER), and
it is used to display and measure the analog NTSC or PAL video signals. The LV 5800’s
newest functions related

This unit displays and measures analog NTSC/PAL composite video signals.
To display the signal, press the key corresponding to this unit from the front panel, press the A or
B channel key, and press the WFM, VICT, PIC, or STATUS mode selection key.

● Display
The unit automatically detects NTSC or PAL. The detected format is displayed at the upper

y
Setting the Input Channel and External Synchronization
If the vectorscope screen of the same unit is shown in the multi screen display, the input
channel and external synchronization (INT/EXT) settings apply to all scree
ns. Therefore, if
you change the input channel or external synchronization of a selected screen, the change
is also applied to the other screens, and the display changes accordingly.
Phase Display
If multiple vectorscope screens of the same unit are displayed in the multi screen display, the
phase is common to all screens. If you change the phase by turning the function dial (F•D) in
a selected area, the phase also changes in the other areas.
Note
You cannot display input channels A and B at the same time on the multi screen display.
Therefore, to display four different input signals at the same time, you have to install four LV
58SER03 units into the LV 5800/7800.
