Output Attenuation
This control can be used to make minor adjustments to the output power
level, but in normal operation should not be changed from factory settings.
(0 attenuation = full output power.)
Video Input
This control is used to select the composite video input standard. Options
are PAL, and NTSC both with and without 7.5 IRE pedestal.
Video Bitrate (status only)
The video bit rate is automatically maximized in each configuration when
Chaining Input is turned off. This control can be used to set the video
bitrate within the constraints of capacity available in the channel, but only
when Chaining Input is set to ON. Chaining CANNOT be enabled on
normal transmitters, and as such video bit rate control is automatic.
Horizontal resolution
The video coding resolution can be selected from 704, 528, 480 and 352
pixels. For optimum performance, choose a resolution one step better than
your camera’s resolution.
Audio Encoder
The Audio can be turned ON and OFF with this control. Audio is OFF by
default, but there are several audio modes that vary from very high quality
to speech grade that can be selected with this control. One or two channel
audio is supported. For optimum link performance, select the lowest audio
quality necessary to support the mission.
