Model 2611/2612 I -Source operating boundaries
Figure 8-6 shows the operating boundaries for the I-Source. Only the first
quadrant of operation is covered. Operation in the other three quadrants is similar.
Figure 8-6A shows the output characteristics for the I-Source. As shown, the
Model 2611/2612 SourceMeter can output up to 101mA at 200V, or 1.515A at
20V. Note that when sourcing more than 101mA, voltage is limited to 20V.
Figure 8-6B 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” earlier in this section. These limit lines are
boundaries that represent the operating limits of the SourceMeter for this quad-
rant of operation. The operating point can be anywhere inside (or on) these limit
lines. The limit line boundaries for the other quadrants are similar.
