3.6.1. Output Behavior
The VDS 200Q10.x is a four-quadrant source. Four-quadrant operation means that the VDS 200Q10.x can
source and sink current using a programmed voltage in both polarities.
Please note that if a DUT has an input capacitance, this will be discharged through the VDS if the VDS voltage is
reduced below that stored in the capacitor, i.e. the DUT will be completely discharged if the voltage is set to zero.
Likewise, when generating a sine wave, the full power of the amplifier can be applied to a capacitive load. The
current limit of the VDS 200Q10.x applies also to AC operation, like is often found in sinusoidal variations. One
must consider the capacitive reactance at the necessary test frequency when determining if a test could be
performed with a certain DUT.
The full range of voltage and bandwidth can be used with the VDS 200Q10.x series. You are only limited by the
maximum and minimum voltage, as well as the maximum frequency, as set.
For example, both of the following simulations are possible at well over 100 kHz:
