Using a Model 2602 to pulse 10A of current from a bias level of 500mA, into a very low impedance
(100 mΩ), while operating at 40°C ambient temperature; what is the maximum duty cycle?

Operating boundaries
Source or sink
Depending on how it is programmed and what is connected to the output (load or source), the
SourceMeter can operate in any of the four quadrants. The four quadrants of operation are shown
in
Figure 8-3 and Figure 8-4. When operating in the first (I) or third (III) quadrant, the SourceMeter
is operating as a source (V and I have the same polarity). As a source, the SourceMeter is
delivering power to a load.
When operating in the second (II) or fourth (IV) quadrant, the SourceMeter is operating as a sink
(V and I have opposite polarity). As a sink, it is dissipating power rather than sourcing it. An
external source or an energy storage device, such as a capacitor or battery, can force operation in
the sink region.
