Figure 1 Figure 2
Figure 2 shows the limit boundaries of the V-Source,
which characterizes the maximum source value of
presently selected voltage source range. For example,
for 20V source range, the limit line of the voltage
source is 21V. The current compliance limit line
represents the actual compliance value. The
compliance value can be a real value or a range.
These limit lines represent the operating bountaries
of GSM in that quadrant. The GSM can operate
within the limit lines or any point on the limit lines.
The boundaries of the four quadrants are similar.
Current compliance limit of V-Source : The
operating point depends on the load. The figures
below show the operating mode when the GSM is
connected to a 2kΩ and 800Ω resistive load
respectively. The GSM is set to source 50V, and the
current compliance value is set to 50mA.
When a 2kΩ load is connected, the GSM is sourcing
50V to the load, and the current is 25mA. For 800Ω
load which is connected, the current is limited to
50mA by the compliance value, the GSM will not be
able to source its programmed voltage. It will only
output 40V.
