FIG.

The invention relates to the field of single-time systems, in particular, to devices for synchronizing time scales of items located at a large distance using the exchange of radio signals of time, and is an improvement of the device according to the main author. No. 548833.

The aim of the invention is to expand the functionality by providing measurement of the shift of the shifted time scales at any value of the shift value regardless of the propagation time of the signals between the operating and reference hours and the delay times of the signals of the transmitter start pulse generator.

FIG. 1 is a functional electrical block diagram of a device for measuring the shear of offset timescales in FIG. 2 and 3 are timing diagrams for the operation of the device.

The device for measuring the shift of an offset time switch contains working hours 1, a reversible counter 2, a controlled divider 3, a 4 clock pulse generator, a trigger generator 5 of the transmitter, a transmitter 6, a receiver 7, a signal splitter 8, a recorder 9, and a temporary signal discriminator 10.

A device for measuring the offset of the shifted time scales works as follows.

The pulses of the time signals (Fig. 2a, Over) of the working hours 1 are fed to the first controllable input of the divider 3, as well as to the input. Start of the reversible counter 2. The controlled divider 3 switches to the mode of direct transmission of the frequency of the generator pulses 4 clock pulses to the input counter 2, which starts direct counting of pulses. After allowing the radiation through time P, the signal of the start pulse generator 5 is fed to the input of the transmitter 6 and is radiated and is also fed to the second input of the controlled divider 3 and switches it to the frequency division mode of the generator 4 by two. At the point of the model clock, the time signals of the model clock (Figs. 2d, 3d) are emitted, which are received at the point of the working hours. The transported signal (Fig. 2cj) of the test clock and

The retransmitted signal (Fig. 2b, 3b) of the generator of the trigger pulse 5 of the transmitter is amplified in the receiver 7 and fed to the switch / connector of the signals 8, and then fed to the corresponding time difference inputs of the signals tel 10. Further operation of the device is determined by shift V and thereby the order of arrival of signals (Fig. 2 (b).

When V "P + Q (Fig. 2), the broadcast signal is received first (Fig. 2 () exemplary hours, from which

In this case, the time discriminator of signals 10 generates a control signal at the first output supplied to the first input of the controlled one; divider 3 and translating it into
