State Primary Standard of a Unit of Electric Voltage of Alternating Current in the Frequency Range from 30 to 1000 MHz
Reproduction and maintenance of the unit of high frequency voltage. Transferring of the size of the unit of high frequency voltage to the secondary standard by means of the method of comparison with the help of comparator and to the working standards of the 1st class and to the working instruments by means of the method of direct measurements and comparison with the help of comparator
in accordance with DSTU 4363:2004 “Metrology. National verification scheme for measuring instruments of voltage of alternative current in the frequency range from 30 to 1000 MHz”.
