ABSTRACT:
A device for measuring the received signal strength at an Earth station antenna has the capability to provide an accurate pointing indication when the frequency bands and other key characteristics of the satellite signals are not uniform over the coverage area. The device has an input port, a plurality of passive or active signal filters, a filter selector and an output port. The device may further contain a signal amplifier with automatic or manual gain control. A plurality of filters is provided which may be coupled singularly or in combination between the input port and the output port. Each filter or combination of filters is associated with a particular geographic area and capable of allowing the satellite signal assigned to that geographic area to pass while attenuating or blocking other signals, noise and interference. The filter selector is used to connect the appropriate filter or combination of filters between the input port and the output port. A signal amplifier with manual or automatic gain control may be included to provide an output signal at the desired signal level. The output port may be connected to a power measuring unit, antenna pointing meter or other similar device to provide an accurate antenna pointing indication in the particular geographic area corresponding to the filter or filter combination selected.
