V-Source operating boundaries
Model 2601A/2602A V-Source operating boundaries
Figure 4-6 shows the operating boundaries for the V-Source. Only the first quadrant of operation is
covered. Operation in the other three quadrants is similar.
Figure 4-6A shows the output characteristics for the V-Source. As shown, the Series 2601A and
2602A can output up to 6.06V at 3A, or 40.4V at 1A. Note that when sourcing more than 6.06V,
current is limited to 1A.
Figure 4-6B shows the limit lines for the V-Source. The voltage source limit line represents the
maximum source value possible for the presently selected voltage source range. For example, if
you are using the 6V source range, the voltage source limit line is at 6.3V. The current compliance
limit line represents the actual compliance 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.
