V-Source Operating Boundaries - Keithley 6430 Instruction Manual

5-14 Source-Measure Concepts

V-Source operating boundaries

Figure 5-7 shows the operating boundaries for the V-Source. Only the first quadrant of oper-
ation is covered. Operation in the other three quadrants is similar.
Figure 5-7A shows the output characteristics for the V-Source. As shown, the SourceMeter
can output up to 21V at 105mA, or 210V at 10.5mA. Note that when sourcing more than 21V,
current is limited to 10.5mA.
Figure 5-7B 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 exam-
ple, if on the 20V source range, the voltage source limit line is at 21V. The current compliance
limit line represents the actual compliance in effect. Remember that compliance can be real or
range. See Compliance limit. These limit lines are boundaries that represent the operating lim-
its of the SourceMeter 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.
