Signal conditioning device with attenuated fail-safe bypass

A signal conditioning device operating in a first state, and a second state having an RF level that is different from the RF level of the first state, said signal conditioning device comprising:

• a circuit comprising a first end for receiving an input from a premise, and a second end coupled to a CATV system;
• a first signal path coupled to the circuit, the first signal path for applying a variable adjustment to the input, the variable adjustment having a first value and a second value causing a loss across the first end and the second end that is different from the loss caused by the first value;
• and
• a second signal path coupled to the first signal path, the second signal path for applying a non-volatile adjustment to the input, the non-volatile adjustment assigned one of the first value and the second value in response to a change from the first state to the second state,
• wherein the non-volatile adjustment is selected so as to maintain the loss as between the first state and the second state.

A method of maintaining a loss of an input across a first end and a second end of a circuit, the circuit operating in a first state, and a second state having a RF level that is different from the RF level of the first state, said method comprising:

• applying a variable adjustment to the input, the variable adjustment having a plurality of values causing the loss across the first end and the second end;
• assigning to a non-volatile adjustment one of the values of the variable adjustment;
• and
• applying the non-volatile adjustment to the input in response to a change from the first state to the second state,
• wherein the non-volatile adjustment is selected so as to maintain the loss as between the first state and the second state.
