RSW2 Return path ingress control switch

Auxiliary module for NMT-xxx transponders. The main function of the RSW2-A version is the 4 state (0 dB, -6 dB, -50 dB resp. HPF) switch in the return path, this is completed with an ingress measurement function. For the allowed ingress level a minor and a major limit can be set for sending minor and major alarms, while a third limit is set for controlling the switch - if the ingress level exceeds this limit, the switch goes into a predefined state. By switching off this function, the device can be used by the same way as the average ingress switches. The new RSW2-H20-A type can contain an additional attenuator stage if needed, so the device provides two functions in a single module.
