-The arbitrary waveform generator should be configured for a 100 Hz triangle wave with 2.5 volt amplitude 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.

 The setup is the same as the previous experiment except now Scope channel 1 is set to display the transistor V<sub>DS</sub>. The drain voltage is swept using a 3 volt peak to peak ramp with an offset equal to 1.5V from the arbitrary waveform generator. V<sub>DS</sub> is measured by single ended scope input 1+. The drain current is measured by differential scope input 2+/- across the 100Ω resistor R<sub>1</sub>. The setup is the same as the previous experiment except now Scope channel 1 is set to display the transistor V<sub>DS</sub>.

-A stair-step waveform will be needed to drive the gate of the transistor. Using the buffer in the Scopy Signal Generator tool, construct a stair-step waveform with 5 levels on channel 2 (W2). Load the following csv file (extract from archive): {{:university:courses:electronics:stair-step.zip|}}. Set the amplitude to 3V and sampleRate to 100Hz.+A stair-step waveform will be needed to drive the gate of the transistor.
