OPTIONS
OPTION 1 : SSPA provided with Ethernet interface
RS485 or RS232 as base line in option.
OPTION 2 : Antenna / Dummy Load Switch
A switch at the system output can be used for maintenance purpose.
This allows operation of the system either into the antenna, or into the dummy load. This switch
is controlled and monitored in Local and Remote modes.
IMPORTANT : the dummy load is located outside the cabinet
OPTION 3 : RF Input Switch (On-Line/Standby modes)
This switch at the system RF input is used to set-up the system either in On-Line or
Standby mode. This switch is controlled and monitored in Local and Remote modes.
OPTION 4 : ALC (Automatic Level Control)
This option allows the operator to set-up the output power at a defined level. When ALC
mode is selected, the gain adjustment is automatically inactive.
This ALC is controlled and monitored in Local and Remote modes.
OPTION 5 : Power output through WR430 waveguide
OPTION 6: Redundant pre-amplifier
