The setting 75 Ω should be selected if the 50 Ω input impedance is transformed to a
higher impedance using a 75 Ω adapter of the RAZ type (= 25 Ω in series to the input
impedance of the instrument). The correction value in this case is 1.76 dB = 10 log (75
Ω/50 Ω).
All levels specified in this Operating Manual refer to the default setting of the instru-
ment (50 Ω).
