Variable frequency filter (trap) VF4
For a “what-if” analysis prior to shielding measures.
Variable frequency filter (suppression 40 dB = factor 10,000) for a simplified differentiation of the HF radiation sources between 700 and 3000 MHz.
To be connected between the antenna cable and the antenna input socket of the measuring device (by the operator). No battery needed. In combination with the HF59B or the HFE35C the variable frequency filter should only be used together with the log.-per. antenna and the HP800, if possible.
