The output protection diodes act as a varactor (voltage controlled capacitor) as
shown in Figure 5-3. Therefore, when measuring return loss at the
GS1528A/9068A output, it is necessary to take the measurement for both a logic
high and a logic low output condition.
Consequently, the output capacitance of the device is dependent on the logic state
of the output.
