30 by the synchronization input and additional output of the auxiliary generator. The drawing shows a structural electrical circuit of the device. The multifunction generator contains the main and auxiliary generators 1 and 2, each of which consists of switch 3 and 4 waveforms, function converter 5 and b, block 7 and 8, frequency control, electronic switch 9 and 10, integrator 11 and 12, relay elements 13 and 14 with resistors 15-17, output amplifiers 18 and 19, bus 20 of the source of the oscillator frequency control signal of the main generator, bus 21 of the source of the oscillator frequency control signal of the auxiliary generator, bus 22 of the source of the phase control signal oscillation shift, switches 23-25, reference voltage source 26, voltage converter 27 in multidirectional currents with current-generating resistors 2P and 29: and diode bridge switch 30 The device operates as follows. When the auxiliary generator operates in the modulation generator mode, the switches 23-25 are in the position shown in the drawing. In closed circuits, each of which is formed by a series connection of the electronic switch 9 (10), the integrator 11 (12) and the relay element 13 (14), stable self-oscillations are established, which at the outputs of the integrators have a triangular shape, and at the outputs of the relay to elements Rectangular Sine-wave signals are generated at the outputs of the functional transducers 5 and b. The frequency of self-oscillations in the main and auxiliary generators is set by the signals applied to the tires 20 and 21. The amplitude values of the triangular-shaped oscillations at the outputs of the integrator 11 and 12 are reached at the moments of switching of the relay elements 13 and 14 when the total currents at the outputs of the relay elements are equal to zero . Therefore, the amplitude of the triangular oscillations at the output of the relay element 14 is equal by the choice of resistors 16 and 17 with the same nominal resistances. In the auxiliary generator, the amplitudes of the triangular oscillations and the triangular signals are equal by supplying the converter 27 to the input via a switch 24 of a certain fixed level from the source 26 of the reference voltage. The signal of the required form of the auxiliary generator from the output of the second output amplifier 18 can be fed to the bus 20, as a result of which the output signal of the main generator is frequency-modulated. The setting of the oscillation generation mode with adjustable phase shift is made by switching the switches 23-25 to the left position. Due to the connection, through the switch 23 of the inputs of the blocks 7 and B, the control of the frequency of the mezkda, the main and auxiliary generators set the same currents to the inputs of the integrator 11 and 12 and proportional to the voltage on the bus 20. Through the connection of the output of the integrator 12 through the switch 25 with the output of the relay element 13, the auxiliary generator 2 is synchronized in frequency by the primary generator 1. By communicating via the switch 24 of the converter 27 with the bus 22, it is possible by changing and voltage level, regulation of the currents flowing through resistors 26 and 29. These adjustable currents alternate from the output of the diode bridge switch to the input of the relay element 13, thereby adjusting the value of the current transients at the input of the slotted element 13. In As a result, the phase shift between the like oscillations of the main and auxiliary oscillators is adjusted. Thus, in the generator, the phase shift is electronically controlled by a voltage, and it is in principle possible to obtain a linear control characteristic. The generator, in which it is possible to regulate the phase shift between oscillations by voltage, has an extended field of application, since, for example, it can be used as part of automated measuring systems. A multifunctional generator containing a main master oscillator, whose synchronized input is connected to a synchronous input of an auxiliary oscillator, the frequency control inputs of the main master oscillator and an auxiliary generator are connected to the signal source bus, an operating mode switch that distinguishes
