The arbitrary waveform generator should be configured for a 100 Hz triangle wave with 2.5 volt amplitude peak-to-peak and 1.25 volt offset. The differential scope channel 2 (2+/-) measures the current in the resistor (and in the transistor). Scope channel 1 should be connected to display the output of the waveform generator. The current flowing through the transistor is the voltage difference 2+ and 2- divided by the resistor value (100Ω). | The arbitrary waveform generator should be configured for a 100 Hz triangle wave with 2.5 volt amplitude peak-to-peak and 1.25 volt offset.
