Figure 3-32 Exciter Setup Screen
Refer to Figure 3-32, Exciter Setup Screen. The following ia a list of entries on the Exciter
setup screen.
• Power Limit. This adjustable S/W power limit will act as a clamp and will not allow
the user to set the power above this limit either locally on the exciter main screen or
remotely via the external I/O board raise/lower input. The range of this control is 0 to
250 mW.
• GPS Reference, refers to External or Internal GPS receiver use.
External is the normal mode. If used, it requires an external 1PPS input at the rear
panel connector.
Loss of the 1PPS will cause a Digital Status hardware switch fault (lights red) and the
Main Screen > Status > Digital Processing > FLO FPGA Registers will show fault.
