Close

Measurements of theBit OPUS 2 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The theBit OPUS 2 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
