<Impedance>
This command selects the nominal input impedance.
75
Ω
should be selected if the 50
Ω
input impedance is transformed to a higher impe-
dance 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
).
