Filters & Attenuators
Attenuators are used to extend the measuring ranges of our high-frequency measuring devices HFA-3, HFR-4 and Frequency Master IV. They are suitable for measuring higher levels.
The measuring range of our high-frequency measuring devices HFA-3, HFR-4 and Frequency Master IV can be adjusted upwards using external attenuators. Available attenuators are 10 dB and 20 dB. The 10 dB attenuator extends the measurement range upwards by a factor of 10 (10x higher radiation level) and the 20 dB attenuator extends the measurement range upwards by a factor of 100 (100x higher radiation level). The attenuators are simply screwed between the antenna and the measuring device.
In addition to our high-frequency filter MFF-1, there are also special filters that cover frequency ranges that the MFF-1 does not. Please ask us about your special requirements.

High Frequency
High- frequency loads come from the transmission systems of telephone companies (GSM, UMTS, LTE), cordless telephones (DECT telephones), wireless computer networks (WLAN, Bluetooth,...), and radar, radio, TV (DVB), etc. The blood is acidified by this influence and Cell membrane tensions change.
