ELF extremely low frequency, RF radiofrequency, MF magnetic field, EF electric field; ^aThe limit of quantification is the same as the lower limit of the measurement range; ^bIt is possible to perform measurements with different spans or bandwidths; ^cThe start frequency for each span corresponds to 1.2 % of the span. The frequency bands are: 5–100 Hz; 5–200 Hz; 6–500 Hz; 12 Hz-1 kHz; 25 Hz-2 kHz; 120 Hz-10 kHz; 1.2-100 kHz. When in remote mode (disconnected from the control unit), 500 Hz is the minimum span that can be measured; ^dFrequency bands: 87.5 - 108 MHz; 470–790 MHz; 791 – 821 MHz; 832 – 862 MHz; 880 – 915 MHz; 925 – 960 MHz; 1710 – 1785 MHz; 1805 – 1880 MHz; 1880 – 1900 MHz; 1920 – 1980 MHz; 2110 – 2170 MHz; 2400–2485 MHz; 2500 – 2570 MHz; 2620 – 2690 MHz; 3400 – 3600 MHz; 5150 – 5875 MHz; ^eDepending on the frequency band
