Source-Measure Concepts
The general operating boundaries for the SourceMeter are shown in Figure 5-4. In this draw-
ing, the 100mA, 20V and 10mA, 200V magnitudes are nominal values. The actual maximum
output magnitudes of the SourceMeter are 105mA, 21V and 10.5mA, 210V. Also note that the
boundaries are not drawn to scale.
I -Source operating boundaries
Figure 5-5 shows the operating boundaries for the I-Source. Only the first quadrant of oper-
ation is covered. Operation in the other three quadrants is similar.
Figure 5-5A shows the output characteristics for the I-Source. As shown, the SourceMeter
can output up to 10.5mA at 210V, or 105mA at 21V. Note that when sourcing more
than10.5mA, voltage is limited to 21V.
Figure 5-5B 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. For exam-
ple, if on the 100mA current source range, the current source limit line is at 105mA. The volt-
age compliance limit line represents the actual compliance that is in effect. Remember that
compliance can be real or range. See
Compliance limit
. These limit lines are boundaries that
represent the operating limits 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.
