    “power density” (W/m²), a certain distance has to be kept from the HF source. For measurements in the lower frequency limits of the HFW59D, the minimum distance between the antenna tip and the object of measurement should be half a meter.

  • Page 9: Step-By-Step-Instruction To Hf-Measurement

    In order to avoid measurement values to be falsified by the often dominant radiation sources from frequencies below, such as DECT or GSM, the HFW59D is equipped with an internal high pass filter at 2.4 GHz, causing these lower frequencies to be sup- pressed.
