The invention relates to the field of radio engineering and communications and can be used in systems in which it is required to receive signals, including multi-frequency, with spatially distributed points, with predetermined phase relations, often common-mode signals.

Phasing of multi-frequency signals at spaced points is necessary when studying the phase-frequency characteristics of extended non-reciprocal two-terminal networks.

The purpose of the invention is to improve the accuracy of phasing.

The drawing shows a structural electrical circuit of the interphase device.

The mutual phasing device contains the first 1 and second 2 master oscillators of the main harmonic frequency, link 3, the first 4 and second 5 oscillators of the higher harmonic frequency, additional link 6, phase shifters 7.1-7.N phasers 8.1-8.N, generators of multi-frequency signal (MES) 9.1-9.N, selective phase meters lO.l-lO.N, tunable phase shifters 11.1-11.W, as well as directional converters 1 2.-1 2 .Ni,. synchronizing generators 13.1-13.N, phase meters 1D.1-14.N, controlled phase shifters 15.1 15. and frequency multipliers 16.1-16.N forming phase shifters.

The mutual phasing device operates as follows.

Phase shifters 7.1-7.N and additional phase shifters 8.1-8.N provide synphaseness at their outputs

Using a selective phase meter

101 compares the phases of the 1st harmonic of the signal of the MES generator 91 and the output signal of the additional phase shifter 81 m. A selective phase meter 91 generates a skew signal, which is used to control the tunable phase shifter 111. As a result, the common-mode of all EMERCOM generators 9.1-9.N at the frequency mj7 is established. Since the start of the MES generators is carried out by the in-phase signals of frequency S1, then if the phase spectra of the signals — the generators of the MES 9.1–9.N are identical, all the other harmonics are in phase.
