Semiconductor devices, computers, etc. need to have appropriate noise resistance. In general, the noise immunity (disturbance rejection ability) of semiconductors and computers is said to be resistant to predetermined environmental conditions when they operate normally under a magnetic field/electric field strength environment at a predetermined temperature and humidity.

Noise is classified into conducted noise and radiated noise. Radiation noise is generated from a high voltage source and a large current source, and generally the former generates a high impedance wave with a large electric field component, and the latter generates a low impedance wave with a large magnetic field component. This wave becomes a plane wave in the range of distance>>wavelength/2π.

This range is called the far field. On the other hand, the range where the distance is less than the wavelength divided by 2π is called the near field.

In such noise immunity tests, a test chamber surrounded by a shield wall is constructed, and the magnetic field/electric field source and the test object are placed inside the chamber, and the test conditions are controlled from the outside so that the test chamber is isolated from the outside. It is practical to conduct this while forming a magnetic field/strong electric field space (hereinafter referred to as an electromagnetic field space), but at the same time as forming this electromagnetic field space, There is a problem here when trying to accurately control the inside of a test room. In other words, if you try to control the temperature and humidity of the test room by installing ordinary electric/electronic temperature/humidity sensors in the test room, these temperature and humidity sensors will
There is a danger that the humidity sensor may be exposed to strong magnetic and electric fields and operate unnecessarily.

For this reason, tests have traditionally been conducted by supplying air at a predetermined temperature and humidity into the room without using a temperature/humidity sensor for indoor temperature/humidity control, and leaving the actual indoor temperature/humidity as it is. This makes it impossible to perform a heat stress environment compatibility test as part of the noise resistance test. There is also a method that detects the temperature and humidity of the return air from the ventilation system and uses this to represent the temperature and humidity in the room, but this method cannot measure the actual environment where the test object is installed, and it is necessary to more closely approximate it. This causes inconvenience as the number of ventilations must be increased. There is also a method in which a worker enters the test chamber to measure the temperature and humidity, but this is not desirable because the measurer is placed in an environment of a strong magnetic field and one strong electric field, which may endanger human life or human body functions.
