The surveillance system can be configured from one port to over 48 ports. The system shown combines two rack mounted 4 channel 100 watt attenuator banks that connect to the 8 channel RF matrix switch. The 8-channel RF matrix switch is designed with a probe/test port where the signal analysis occurs. The 8-channel switch is bi-directional enabling testing in both directions. The system frequency can be customized to the end user’s specification.
