Description

(54) SAMPLE ATTENDUATOR

one

The invention relates to a measurement technique and can be used in radio engineering installations for various purposes.

A gated attenuator is known that contains a limit attenuator in series, a pulse shaper, a correction unit, a reversible counter, a digital indicator connected to a reversible counter and a correction unit, a comparison unit and a correction signal input unit (1 |.

However, the known exemplary attenuator has a high attenuation error.

The purpose of the invention is to reduce the error error of the attenuation.

To achieve this goal, an exemplary attenuator containing a limit attenuator connected in series, a pulse shaper, a correction unit, a reversible counter, a digital indicator connected to a reversible counter and a correction unit, a comparison unit and a correction signal input unit, a memory block and an analysis unit, and outputs

the memory unit is connected to the inputs of the correction unit, the comparator unit and the analysis unit, the first input is connected to the output of the correction signal input unit, and the second one is connected to the output of the analysis unit, the second input

 the analysis unit is connected to the output of the reversible counter.

The drawing shows a trrpyKTypHaH electrical circuit of an exemplary attenuator ..

10 An exemplary attenuator contains a limiting attenuator 1, a shaper 2 pulses, a correction block 3, a reversible counter 4, a comparison block 5, a memory block 6, a correction signal input block 7, an analysis block 8. and a digital indicator 9.

The proposed exemplary attenuator works as follows.

The limiting waveguide, which is a component of limiting attenuator I, is split 20 along the axis and the sections. Each section corresponds to its own correction of attenuation stored in memory block 6.

Through the block 7 input of the correction signal to the first input of the block 6 of the memory is made
