Методика nposjepKH стробоскопичес .ких осштлографов, МИ 14-74, М,, Изд стандартов, 1974, с. 22 (прототип).CHARACTERISTICS OF BROADBAND RADIO-MEASURING INSTRUMENTS 1, determined by the directional aperiodic probe 4 of the 3 liHJW transmission, will be the sum of the falling and reflected voltage waves, real. Sechengsh, c. the probe 4 is installed, as well as in all sections of line 3, distance from the section of probe 4 at a distance equal to lxl / 2, where ll is the length of the segment 3 lines of nonredach, η - 1, 2, 3 In the TBKITM manner, the direction developed by probe 4 will be proportional to the sum of the incident and reflected waves of the voltages acting in the section of the radio input of the measuring device 5, the invention allows to ensure that the input of the radio measuring device 5 is constant: the sum of the falling and reflected voltage waves what is the condition of measuring the frequency response without methodological error and increasing the measurement precision LCHH. Apparatus of the Invention A device for measuring the amplitude of the frequency characteristics of wideband radio meters, contains a signal generator and an input signal indicator, characterized in that, in order to improve measurement accuracy, a transmission line segment and a probe are input, with the output of the signal generator connected to the transmission line segment input from the output of which the signal is fed to a radio measuring device, the probe input being located in a segment of the transmission line at a distance from its input, a multiple of half the wavelength, and a probe connected to the input stroke input indicator.
