 Replace the 1N4001 diode with the 1N3064 diode from the Kit and repeat the same set of sweeps you just did for the first diode. Fill out another table with your measured data and calculated C<​sub>​diode</​sub>​ values. How do the 1N3064 values compare to those for the 1N4001 diode? You should include a plot of the diode capacitance vs. reverse bias voltage for each diode you measure in your lab report. Replace the 1N4001 diode with the 1N3064 diode from the Kit and repeat the same set of sweeps you just did for the first diode.

 Include your calculations,​ a table and plot of your measured capacitance vs. voltage for each transistor in your lab report. Compare your measured C-B capacitance to the manufacturer'​s data sheet for these transistors. Note, data sheets don't often list the C-B capacitance directly. It is often included as part of the output capacitance or something similar. Include your calculations,​ a table and plot of your measured capacitance vs. voltage for each transistor in your lab report.
