Figure E 16: Attenuator Configuration
These attenuators and the above x5 amp are selected automatically by setting the
output voltage.
This block gives an offset voltage to the output. This circuit is a power source
that can both push out and pull in. The offset voltage is calculated for output
terminated with exactly 50 W. Since this circuit has a capacity of 100 mA, an
offset of up to 100 mA
independent of the output voltage setting.
This makes it possible to simulate a waveform that has a large offset voltage
with an extremely small signal. Figure E-17 shows the offset circuit.
