A detector circuit operating in parallel with a bandwidth limited measurement channel in a measurement instrument generates a warning signal when an input signal exceeds a predetermined repetition rate or has a pulse width less than a predetermined value. To provide a warning signal to the measurement instrument that the input signal contains high frequency components that are likely to be missed by the measurement channel, the detector circuit operates in parallel with the measurement channel. A pulse width in the input signal that is sufficiently narrow or a repetition rate that is too high causes the detector to generate the warning signal that is provided to the measurement instrument.
