DESCRIPTION

The RF Commutator is designed for switching sine-wave and pulse signals.

May be used in automatic measurement, information and process control systems.

PRINCIPLE OF OPERATION

The RF Commutator principle of operation is based on control of electromagnetic contacts providing the channel switching.

Using the Commutator front panel controls or over the IEC 625 interface bus control signals are applied to relay units switching RF signals from input to output.

The Commutator provides switching of one of 50 input channels to any of 5 output channels.
