Key Label Description

SWEEP Press to cycle the waveform between 1H (one horizontal line of video), 2H

(two successive lines of video), 1V (one vertical field of video), or 2V (two

successive fields of video).

1H, 2H, 1V, 2V LED lights to indicate which SWEEP is currently in operation.

H. MAG Press to select, for the waveform display, either a normal horizontal sweep or

a sweep that has been horizontally magnified by a factor of 5.

x5 LED lights when the horizontal waveform sweep has been magnified by a

factor of 5.

V. GAIN Press to select, for the waveform display, either a vertical gain of 1 or a

vertical gain of 2.5.

x2.5 LED lights when the vertical waveform gain has been increased by a factor of

2.5.

FORMAT Press to select the format in which the waveform is displayed. Component

video at the C or D video inputs can be displayed as either RGB components

(which may be paraded or overlaid) Y, C

, C

components (which may be

paraded or overlaid), or as an equivalent COMPOSITE waveform which has

been synthesized internal to the VTM-200. The waveforms of NTSC/PAL

signals at the A or B video inputs can only be displayed in COMPOSITE

format. The vectors display for component video inputs displays Cb vs. Cr.

The vector display for composite video inputs displays B-Y vs. R-Y.

RGB, YC

COMPOSITE

LED lights to indicate which display FORMAT has been selected.

AUDIO (ZOOM) This button has a dual purpose:

 Press to select, for the audio levels display, either the SETUP pre-

selected scales calibrated in dB or scales that have been zoomed in the

region of 0 dB to display more detail.

 When the SETUP menu is displayed, this button functions to select only

those items concerned with audio, and forces the menu to appear in the

screen quadrant normally occupied by the vector display. This button is

active only when the OPT-1 option is installed.

ON (AUDIO ZOOM) LED lights when the audio scales have been zoomed to present a more

detailed display.

VECTOR (ZOOM) Press to cycle through the vector display through different views. These

include normal display, center zoomed display, and one vector quadrant

zoomed display, as follows:

ON (VECTOR ZOOM) LED lights when a vector display other than the normal display is shown.
