FIELD: radio measurement technology. SUBSTANCE: proposed method that may be used in designing miscellaneous broadband measuring systems to ensure super-broadband self-synchronization during measurements involves time-scaling conversion of source sync signal; generation of differential signal from converted and reference signals; variation of time-scaling conversion process to maintain it at preset point; generation of standard sync signal related to preset point of source sync signal. Device implementing proposed method has mixer whose first input functions as device input, second input is connected to output of sample pulse shaper, output is connected to input of stretcher whose first output is connected to third input of mixer and second output, to first input of subtraction unit; second input of the latter is connected to output of comparison signal shaper and output, to input of master oscillator; first output of the latter is connected to input of sample pulse shaper and second input, to input of standard sync pulse shaper whose output functions as device output. EFFECT: extended frequency band; enhanced sensitivity of self-synchronization process. 4 cl, 1 dwg
