Overvoltage Protection
The overvoltage protection prevent overloading by an external signal applied to the RF output of the
R&S SMB Signal Generator.
The overload protection is tripped when the power of the external signal becomes too high. A relay
opens and interrupts the connection between the RF output and attenuator. This condition is indicated
in the display header by the 'OVERLOAD' status message.
! Reset the overload protection by pressing the
RF ON/OFF key. The RF input is activated when the
overload protection is reset.
