4.2.4 Vectorscope Mode
• This mode provides the vectorscope displays of input pictures.
• You can magnify the black and white levels (×1, ×2, or ×4).
• You can select from the 100% and 75% color bars for the markers. (Use the menu mode to
select from the markers.)
• In addition to the regular XY axes, IQ axes are displayed for the scale.
• The line select function (LINE SEL switch) is available.
When this function is used, the screen presents a 1H-sweep display (or 2H-sweep display, if
this display mode has been selected).
• When an HDTV signal is being input, turning off the line select function results in the
sampling of lines through a decimation process.
• When an SDTV signal is being input, turning off the line select function results in the
sampling of all lines.
• You can use the settings of selected lines also in other modes since the settings are retained.
• The picture overlay function (OVERLAY switch) is available.
When the line select function is in use, the position of a selected line is shown on the overlay
picture.

F4  Switches between the fields.
F5  Selects from the options of black- and white-level magnification.
 F1:
(LINE INC)
Increments the number of lines to be selected.
You can specify the number and show waveforms on a 1H-sweep basis. If
you select a 2H-sweep display, the monitor presents a 2H-sweep display of
waveforms. This option is not shown in the menu when LINE SEL is set to
OFF.
 F2:
(LINE DEC)
Decrements the number of lines to be selected.
You can specify the number and show waveforms on a 1H-sweep basis. If
you select a 2H-sweep display, the monitor presents a 2H-sweep display of
waveforms. This option is not shown in the menu when LINE SEL is set to
OFF.
 F3:
(LINE SEL OFF/ON)
Turns on/off the line select function. This option appears when the LINE
SELECT menu is enabled (LINE SEL switch is pressed).
 F4:
(FIELD)
Switches between the fields.
This option is effective only when the input signal is in the interlace format
or segment frame format. This option is not shown in the menu in the case
of the progressive format.
 F5:
(GAIN ×1/×2/×4)
Selects from the options of a channel’s black- and white-level magnification.
You can select from the ×1, ×2 and ×4 options of GAIN.
