This example gathers data to construct a graph showing the gain of a bipolar device over a wide range of
base currents. A fixed collector-emitter bias is generated by SMU2. A logarithmic base current from
1.0E-10 to 1.0E-1A is generated by SMU1 using the asweepi command. The collector current applied by
SMU2 is measured 10 times by the smeasi command. The data gathered is then stored in the icmeas
array.
