Summary of VCCI V-3 Compliance Testing

VCCI evaluates interference from information technology equipment (ITE). The ITE standard regards disturbance limit, measuring method, and measuring facilities that are necessary for compliance of ITE equipment.

Multiple different types of equipment may be used within the VCCI V-3 ITE standard test method. Equipment includes:

  • Multi-Function Equipment: This is ITE in which two or more functions are subjected to this VCCI standard or other standards provided. This includes a personal computer provided with a telecommunication function and/or broadcast reception function. Multi-Function equipment may also be considered a personal computer provided with a measuring function, etc.
  • Peripheral Equipment: This type of equipment is equipment making up a typical configuration of EUT together with host equipment. They are arranged for the proper operation of EUT.
  • Auxiliary Equipment: Auxiliary equipment is equipment connected to host equipment via a telecommunication network, local area network, and similar equipment.

Scope of VCCI Information Technology Equipment Testing

The equipment under test must meet specific limits of a disturbance at main ports. This includes the average limits and quasi-peak limits when using an average detector receiver. Additionally, it includes a quasi-peak detector receiver that is measured per other VCCI methods.

Limits for conducted disturbance telecommunication ports must meet the average limit and the quasi-peak limit as well. This is only when measured using an average detector receiver and quasi-peak detector receiver.

Limits for radiated disturbances are also carried out in VCCI V-3. The quasi-peak level of the field strength of radiated disturbance from the EUT must meet limits within the V-3 standard. This is when measured following the method specified by the technical requirements.

Lastly, confirmation of compliance within the mentioned limits above is crucial during VCCI V-3 testing. The test must be made to one sample arbitrarily selected among the mass of produced products. Sometimes compliance equipment cannot be confirmed with one sample test, If this is true, the assessment is made by statistical methods.
