 Scope channel 1 measures the solar panel voltage with input 1+ connected to the + terminal of the panel and input 1- connected to the - terminal of the panel. Scope channel 2 measures the current by measuring the voltage across 10 Ω resistor R<sub>1</sub> with input 2+ connected to the source terminal of M<sub>1</sub> and input 2- connected to the - terminal of the panel.
-The configuration shown in figure 9 can measure only part of the I/V curve for panels with V<sub>OC</sub> greater than about 5V. It should be used to measure I<sub>SC</sub>for any panel. To measure the rest of the I/V curve for panels with V<sub>OC</sub> up to 10 volts the circuit can be modified as shown in figure 10. The waveform generator in the Discovery can swing a maximum of 10 Volts (-5 to +5) so that will be the ultimate limit of the total voltage range of any I/V measurements that can be produced using these setups.
