The nonautonomous generation of chaotic microwave pulses in the wideband chaos oscillators is experimentally investigated. Nonlinearity of a spinwave transmission line is a cause of chaotic dynamics of the spinwave chaos oscillator and nonlinearity of a TWT amplifier is a cause of chaotic dynamics of the other chaos oscillator. It is shown, that in both cases, the generation of chaotic microwave pulses is observed when an external pulsemodulated microwave signal has a certain power level and its carrier is detuned from a central frequency of a chaotic signal.
