FIELD: measuring equipment.
SUBSTANCE: method for testing a test device is characterized by that a first module of source/meter is connected to a first set of at least three triaxial cables and a ground terminal. Each triaxial cable comprises a central signal conductor, an outer screen and an average conductor, the outer screens of the first set of triaxial cables are electrically connected together with the ground terminal. Then the second end of each cable is connected from the first set of triaxial cables to the set of test device units. The second meter is connected to the second set of at least three triaxial cables and having a central signal conductor, an outer screen, a middle conductor and a ground terminal. Each of the three test points is connected to the first end of the central signal conductor of each cable from the second set of three triaxial cables, respectively. And the outer screens of the second set of triaxial cables are electrically connected with the ground terminal. The second end of each cable is connected from the second set of triaxial cables to said set of the test device units. External screens of cables of both first and second sets of triaxial cables are connected together and grounded.
EFFECT: increased measurement stability.
