Figure 4-3A shows the output characteristics for the I-Source. As shown, the Series 2601A and
2602A can output up to 1.01A at 40V, or 3.03A at 6V. Note that when sourcing more than 1.01A,
voltage is limited to 6V.
Figure 4-3B shows the limit lines for the I-Source. The current source limit line represents the
maximum source value possible for the presently selected current source range. The voltage
compliance limit line represents the actual compliance that is in effect (see
Compliance limit ).
These limit lines are boundaries that represent the operating limits of the SourceMeter instrument
for this quadrant of operation. The operating point can be anywhere inside (or on) these limit lines.
The limit line boundaries for the other quadrants are similar.
