域掃引信号発生器。[Claims for Utility Model Registration] The output of a voltage controlled oscillator and the output of a carrier wave oscillator are frequency-mixed and the difference between the two is output, and in one sweep period T, the sweep frequency is from approximately zero to the maximum sweep. In a sweep signal generator that sweeps linearly with time up to a frequency f max , after starting the sweep, the frequency of the voltage controlled oscillator is lower than 2f max by f max +△f (but △
linearly decreases to f〈f max ), and time T 1 =
T×f max △ff max f max +△
a sweep voltage generating means for supplying a sweep voltage to the voltage controlled oscillator so that the 1- time frequency is maintained at f max +Δf after reaching f; control voltage generating means for supplying a control voltage to the carrier wave oscillator so that the frequency of the carrier wave oscillator is maintained at 2f max for a time T1 , and thereafter the frequency of the carrier wave oscillator is controlled to linearly increase by Δf during ΔT; A wideband sweep signal generator comprising:
