Zusammenfassung:The present invention relates to system diagnostic circuitry for antenna systems with active antenna components. More specifically, the present invention discloses an apparatus comprising a connection between an antenna and a power supply conducting a first DC voltage, a source of a pulse width modulated signal, a lowpass filter for converting the pulse width modulated signal to a second DC voltage, and a comparator for comparing the first DC voltage and the second DC voltage and generating an output signal responsive to the difference between the first DC voltage and the second DC voltage.
