The invention relates to a measurement technique and can be used to apply time stamps to a moving photon tape in light-beam oscilloscopes.

A known timer for a light-beam oscilloscope, containing a variable-amplitude sinusoidal shaper, made in the form of a generator of discontinuous sinusoidal signals, an output shunt with an on-time relay, whose control input is connected to the output of the specified shaper ij.

This time stamper gives two frequencies in the ratio of 1:10 superimposed on each other, with each tenth point having a larger amplitude. Such a timer is unreliable in operation due to its application and can only be used in the low frequency range.

The closest to the invention is a timer for a light-beam oscilloscope, which contains a switch, a series-connected stable frequency source, a square pulse shaper and frequency dividers, as well as a decoder with indication, an inverter, an n + 1 RC circuit and series-connected element OR, an amplifier and an oscillographic galvanometer, the decoder input with an induction being connected via a switch With the outputs of the frequency dividers, and the output of the driver through serially connected inverters Op KStsep and connected to an input of the OR gate whose other inputs through the remaining RC-circuit connected to the second output of frequency dividers, respectively.

In this timer, signals from a stable frequency source are converted by the shaper to square pulses.

Pulses with the same contrast, but different amplitudes for each single, tenth, thousand of them are applied to the moving photo tape 2.

However, this time stamper does not allow timestamps of multiple multiples and non-core frequencies to be applied at the same time to the phototape, which reduces its information content.

The purpose of the invention is to increase the information content by marking time marks at multiple and non-multiple frequencies of different polarities.

The goal is achieved in those that in the timer for a light beam oscilloscope containing series-connected sources

a stable frequency, a square pulse shaper and h dividers, n + 1 RC circuits connected to the second output of the frequency dividers, respectively, as well as a series-connected amplifier and oscillographic galvanometer, the amplifier is differential and amplitude limiters are input. the amplifier is connected to the Part of the outputs of the amplitude limiters, one of which is connected through the RC circuit to one of the outputs of the rectangular pulse former, the other amplitude limit The niches are connected to the outputs with a non-inverting input of a differential amplifier, and the inputs to the corresponding outputs of an RC circuit,

The drawing is a block diagram of a timer.

Timer contains after-; formatively connected source 1 of stable frequency, shaper 2 of rectangular pulses, dividers 3 frequencies, RC-depi 4 connected to the second outputs of frequency dividers, respectively, amplitude limiters 5, connected in series differential amplifier 6; and oscillographic galvanometer 7, while the inverting input of the differential amplifier b is connected to a part of the outputs of amplitude limiters 5, one of which is connected via RC-circuit 4 to one of the outputs of the forcing 2 square pulses b, inputs with corresponding outputs of RC circuits 4,

The marker works in the following way.

Signals from a stable frequency source 1 are converted by shaper 2 into square pulses, which are fed to the RC circuit 4. From the RC circuit 4 output, a sequence of positive and negative pulses is fed to the input of the amplitude limiter 5, which transmits positive pulses to the inverting input of the differential amplifier 6

The rectangular pulses from the imaging unit 2 also arrive at the inputs of series-connected frequency dividers 3. From the output of some of the signals through the RC-circuit 4 and amplitude limiters 5, the input of the differential amplifier b goes to inverting, and from the output of the remaining dividers 3 frequencies through RC-circuit 4 and the amplitude limiters 5 to the non-inverting input dif3-1061053 4.
