V-source operating boundaries
The following figures show the operating boundaries for the voltage source. Only the first quadrant of
operation is shown. Operation in the other quadrant is similar.
The following figure shows the output characteristics for the voltage source. The 2606B can output up
to 6.06 V at 3 A, or 20.2 V at 1 mA. Note that when sourcing more than 6.06 V, current is limited
to 1 A.

The following figure shows the limit lines for the voltage 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 20 V source range, the voltage source limit line is at 20.2 V. The current
compliance limit line represents the actual limit in effect. These limit lines are boundaries that
represent the operating limits of the 2606B 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.
