We purchased our absorber material many years ago now, so things maybe different than it was then.
We were told that the absorber material most labs were using for 61000-4-3 testing above 1Ghz was “Too Tall” to be used for S-VSWR verification. So we worked with TDK who recommended a shorter absorbing material which should meet both requirements. Though we purchased and use this material and get good unified field data for 61000-4-3, we have never tested this material in the S-VSWR verification setup. Someday when we expand our radiated emissions testing above 1Ghz we will find out. So bottom line, I recommend working with an absorber manufacture to help you find a material that will meet your specific needs. Hope this information was helpful.

I was told different type/model of the absorbers must be used. Is this true? Thank you very much.
