In case of stereo
sound.
5.5.1 Video
The modulation depth can be adjusted in this submenu.
•
In case the VAGC is off
Change the modulation depth by pressing the
UP
/
DOWN
arrows. The little black rectangle on the scale
indicates a modulation depth of 90%. The modulation depth is constantly measured while the result
is displayed on the right part of the screen. The vertical line on the scale is an indication for this
measured value. While pressing the arrows, the black rectangle disappears and the scale is now an
indication for the total available control range.
The white limiter is active if the letter ‘W’ is in front of the modulation depth value.
•
In case the VAGC is on
Change the modulation depth by pressing the
UP
/
DOWN
arrows. The video AGC will control the gain
to the desired modulation depth. The first line of the display shows the desired modulation depth
while the measured value is shown on the right part of the display and also indicated by the vertical
line on the scale. After AGC autoranging, the vertical line shoud be on top of the black rectangle.
5.5.2 Audio
The frequency deviation is indicated on this display. The deviation can be changed with the
UP
and
DOWN
arrow. The black rectangle is an indication of the reference value of 50 kHz. The vertical line on
the scale is an indication of the measured value, which is also shown on the display. While pushing the
arrows, the black rectangle disappears, the horizontal line is now an indication of the total control range.
