Сreating a precision circuits for discharge of charge integrator for use in spectrometric devices for observations in the far space

The method of circuit realization of an electronic key for discharge of the charge integrator in specific applications, due to the carrying out spectrometric measurements of solar radiation in space experiments is described. Data of laboratory tests of synthesized circuit and the evaluation of the introduced measurement error of the solar flux by means of CCD-matrices with the use of this circuit is presented. This problem is considered from the point of view of application in the INTERHELIOPROBE project in the solar photometer. The impossibility of the implementation of the electronic key for discharge of the charge integrator by using the classical approach is shown. A complicated scheme of implementation of the electronic key is presented and the data of laboratory tests of this scheme are discussed. It is shown that the scheme of an electronic key for discharge of the charge integrator can be successfully implemented from electronic components currently produced in Russia.
