Description
Technical field
The utility model relates to electronic surveyings and signal analysis technology field more particularly to a kind of disturbance power test macro
In use testboard.
Background technique
Disturbance power, that is, Electro Magnetic Compatibility refers to that equipment or system meet the requirements operation not to it in its electromagnetic environment
Any equipment in environment generates the ability of intolerable electromagnetic interference.Therefore, disturbance power includes the requirement of two aspects:
On the one hand refer to equipment in normal course of operation to place environment generate electromagnetic interference no more than certain limit value；It is another
Aspect refers to that utensil has a degree of immunity to interference, i.e. electromagnetic susceptibility to electromagnetic interference present in the environment of place.
It is small in size for equipment such as household electrical appliance, power supply wire length, in 30MHz or more, radiation caused by household electrical appliance
Harassing and wrecking energy is mainly to pass through the power supply line close to utensil to external radiation, and disturbance power test electronic electric equipment passes through power supply
The electromagnetic disturbance power that line, interconnection line and signal wire radiate.For only connecting a power supply line (or other types lead)
Small-sized tested material, such as household appliances and electric tool, standard think: the radiation-emitting as caused by common mode current on lead,
It is far longer than the outside radiation in tested material surface.It generallys use absorbing clamp measurement method (ACMM), ACMM carries out radiation emission measurement
The advantages of be to shorten the testing time and to save space expense (can carry out in screened room).
It is existing in the market to be realized for testboard used in disturbance power test macro by low Electromagnetic Launching motor
Disturbance power absorbing clamp electronic round-trip function on crawler belt, and low Electromagnetic Launching motor will impact test environment, shadow
The accuracy for having rung disturbance power test, haves the defects that certain.
For this purpose, we have proposed use testboard in a kind of disturbance power test macro.
