Figure E￿16: Attenuator Configuration

These attenuators and the above x5 amp are selected automatically by setting the output voltage.

Offset 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 25 W (50 W 50 W) = ±2.5 V can be applied 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.
