shows the operating boundaries for the V-Source. Only the first quadrant of operation is
covered. Operation in the other three quadrants is similar.
shows the output characteristics for the V-Source. As shown, the Series 2611A/
2612A/2635A/2636A can output up to 20.2V at 1.5A, or 202V at 100mA. Note that when sourcing
more than 20.2V, current is limited to 100mA.
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 20V source range, the voltage source limit line is at 20.2V. The current
compliance limit line represents the actual compliance in effect (see
). 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.
