Operating boundaries

Source or sink

Depending on how it is programmed and what is connected to the output (load or source), the

instrument can operate in any of the four quadrants. The four quadrants of operation are shown in the

continuous operating boundaries figures. When operating in the first (I) or third (III) quadrant, the

instrument is operating as a source (V and I have the same polarity). As a source, the instrument is

delivering power to a load.

Figure 89: Four quadrants of operation

When operating in the second (II) or fourth (IV) quadrant, the instrument is operating as a sink (V and

I have opposite polarity). As a sink, it is dissipating power rather than sourcing it. An external source

or an energy storage device, such as a capacitor or battery, can force operation in the sink region.
