METHOD OF TESTING RADIO ENGINEERING ARTICLES Russian patent published in 2011 - IPC G01M99/00 

FIELD: physics.

SUBSTANCE: shielded chamber is formed, where part of the walls of the chamber. The floor and top, whose dimensions are greater than dimensions of the article to undergo testing, are heat insulating and heating and cooling systems, as well as a ventilator for moving air are placed in that part of the shielded chamber. The remaining part of the shielded chamber is finished taking into account requirements for clean facilities and is also fitted with air filters. The test article is placed in the heat insulating part of the shielded chamber and one or more heat insulating partitions shielding the test article, having a door and working holes for electrical connections of the test article and measurement apparatus are mounted, forming a climatic compartment. Thermal effect which is different for each test article is created, while, if needed, simultaneously transmitting to and receiving signals from the test article using the measurement apparatus. Cooling and air preparation equipment are placed outside of inside the shielded chamber.

EFFECT: possibility of performing climatic tests in conditions of protection from the effect of external electromagnetic radiation with high degree of cleanness of facilities and associated controlled media with different dimensions of large-sized radio engineering articles.
