TRACEABLE BUILT-IN PROGRAMMABLE FREQUENCY GENERATOR FOR COMPARING ALTERNATE TEST SITE WITH OPEN AREA TEST SITE

Title:

TRACEABLE BUILT-IN PROGRAMMABLE FREQUENCY GENERATOR FOR COMPARING ALTERNATE TEST SITE WITH OPEN AREA TEST SITE

Document Type and Number:

Japanese Patent JP2000088906

Kind Code:

A

Abstract:

To provide an excellent EMI measuring signal source which could not have been obtained by a conventional technology.

A site reference signal source operates as a programmable frequency generation source, and contains a symmetrical radiation unit. The unit contains a cylindrical structure 13, a signal generator 26, a power source 23, and an antenna 14. The generator 26 is contained in the structure 13. The power source is also contained in the structure 13. The power source 23 supplies power to the generator 26. The antenna 14 is provided an exterior of the structure 13. The antenna 14 is electrically connected to the generator 26 contained in the structure 13. To radiate a signal, the generator 26 generates the signal and transmits the signal to the antenna via the structure 13.
