The field strength measurement in swept SA mode is not the general
measurement items of 'field strength meter'. The field strength meter is
only a normal level measurement meter among measurement devices. The
real field strngth measurement refers to level measurement meter and the
antenna. The unit is always dBuV/m. To choose the field strength
measurement type, see the interface of figure 3-104
Supported units:
2
dBm/ m , dBV/m, dBmV/m, dBμV/m, Volt/m, Watt/ m
Calculation formula:
(E) dBμv/M = (Vo) dBμv + (AF) dB/M
Electric field intensity E(V/m)
Power density S(W/ m
Value range with different unit:
dBμV
dBμV/m
