NG500 (Rev. 0)
If the circuit, as is usually the case, is closed on the typical impedance which is the same as that
of the generator (i.e., 1000
Ω
), the voltage is decreased to half (2 µV).
On the basis of what has been briefly exposed, the noise generator NG500 may be represented
with the equivalent circuit as shown in figure 11 where the amplifier “A” has a bandwidth of
2000 MHz and an internal resistance of 75
Ω
.
