Why shall an half of the voltage setting on the FNS be measured on the scope?
NoiseKenThe EFT/B generator output impedance is 50Ω. When the AT-810 attenuator whose input impedance is 50 ohm terminates the generator output, the following formula applies:
Voltage setting on the FNS (open circuit voltage) × (50Ω/50Ω+50Ω)= voltage being measured on the scope.
