Important precautions and Maintenance 

 

Precautions 

The Conducted Comb Generator is an conducted signal source designed to produces signals 

over wide frequency range to verify conducted emissions test setup that utilize Line Impedance 

Stabilization Networks. It was designed for use in EMI test laboratory. 

 

 

 

Denotes: Read and understand user manual carefully before operating the 

equipment.  

 

Maintenance

 

There are no user serviceable parts inside the unit.  User modifications to the Comb Generator
