amplifies the video signals to the proper level to
drive the video through a maximum of 1,000 feet of
cable for each output.
SDDS Front Panels and Controls
The sweep/passive function SDDS front panel is
shown in figure 4-10.
The front panel contains
three power meters to allow for monitoring of the
power supply outputs. The 20 user toggle switches
allow the operator or technician to locally select the
sensor and video that are routed to a particular
display console or group of consoles. When the
toggle switch is in the LOCAL position, the
associated console will receive sweep and video data
selected by the SENSOR and VIDEO rotary
switches.
When the toggle switch is in the
REMOTE position, sensor and video selection is
controlled by the switches on the display console.
The front panel for the video function SDDS is very
similar to the passive/sweep function front panel.
The front panel for the sweep/IFF function SDDS is
shown in figure 4-11.
All switches for the
sweep/IFF function drawer are controlled by the
video function drawer.
