| - | The waveform generator should be configured for a 100 Hz triangle wave with 3 volt amplitude and 0 volt offset. The differential input of scope channel 2 (2+,2-) is used to measure the current in the resistor (and diode). The single ended input of scope channel 1 (1+) is used to measure the voltage across the diode (1- input is grounded). The Scope should be setup with channel 1 at 500mV per division and channel 2 set also at 500mV per division. The current flowing through the diode, I<sub>D</sub>, is the voltage measured by channel 2 divided by the resistor value (100 ? in this example). Use the XY display mode to plot the voltage across the diode (scope channel 1) on the X axis vs. the current in the diode (scope channel 2) on the Y axis. | + | The waveform generator should be configured for a 100 Hz triangle wave with 3 volt amplitude and 0 volt offset.
