6.2 Input Z Correction
Input Impedance include 50 Ohm and 75 Ohm, default 50 Ohm. A adaptor of 75 Ohm to 50 Ohm is
required, when the input impedance select 75 Ohm.
The selection of input impedance will influence calculation result only. That influence include
voltage and electric current (dBmV, dBuV, dBuA, V, A), but power.
