 This project requires a small external circuit on which to perform the frequency sweep. The circuit consists of a capacitor and resistor in a low-pass RC filter configuration. Please refer to Figure 1 while creating this circuit and connecting it to your Test and Measurement device. This project requires a small external circuit on which to perform the frequency sweep.

 Measure the capacitor'​s capacitance and replace the default value set on the first line of the script (in the //Script// tab, following the comment block). Be sure to pay attention to the order of magnitude and change the second value in "​Math.pow()"​ accordingly (this is the power to raise 10 by). Decide on the desired cutoff frequency, or leave it as is. Measure the capacitor'​s capacitance and replace the default value set on the first line of the script (in the //Script// tab, following the comment block).
