I-source operating boundaries
The following figures show the operating boundaries for the I-source. Only the first quadrant of
operation is shown; operation in the other quadrant is similar.
The first figure shows the output characteristics for the I-source. As shown, the 2606B can output up
to 1.01 A at 20 V, or 3.03 A at 6 V. Note that when sourcing more than 1.01 A, voltage is limited to
6 V.
Figure 84: I-source output characteristics
The following figure 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
(on page 2-35)).
These limit lines are boundaries that represent the operating limits of the 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 quadrant is similar.
