Figure 82: Voltage source operation in power compliance
Voltage source sweep operation in current and power compliance
The following figure shows a voltage sweep on a resistive load of 800
Ω
.
For this example, the 2606B
is programmed to sweep voltage to 10 V, limit current (6 mA) and limit power (50 mW). When
sweeping, the actual source output varies according to the programmed source value until the current
limit is reached. As the figure shows, the output sources the programmed value until placed in current
compliance at the 6 mA limit. The sweep then continues. Programmed current source values increase
along the green sweep points line, but the output remains at the value it was at when the instrument
went into voltage compliance. This continues until the programmed source value sweeps to a high
enough level that the power limit line is reached (50 mW). At this point, the current and voltage start
to decrease, lowering the current and voltage values along the DUT load line. When the last point is
swept (10 V), the actual output is 10 V (at 5 mA).
