Set up the solar cell I-V sweep using SCPI commands
The example sequence of SCPI commands generates an I-V sweep on a solar cell. You may need to
make changes so that this code will run in your programming environment.
In this example, the voltage is swept from 0 V to 0.55 V in 56 steps. The resulting solar cell current is
measured. The current and voltage measurements are stored in default buffer 1 (defbuffer1).
Send the following commands for this example application:
