| - | Build the measurement setup as shown in figure 5 below. If you are using the HPH1-1400L transformer for T<sub>1</sub> you should connect three of the 6 windings in series for the primary and the remaining three windings in series for the secondary ( see this [[university:labs:m2k:comms_lab_transformers|activity on transformers]] for more details ). | + | Build the measurement setup as shown in figure 5 below.

| There are three resistors, R<sub>C</sub>, R<sub>B</sub>, R<sub>E</sub> and one capacitor, C<sub>M</sub>, that determine the loop gain of this circuit. You will be running frequency sweeps with the network analyzer testing various combinations of component values. | There are three resistors, R<sub>C</sub>, R<sub>B</sub>, R<sub>E</sub> and one capacitor, C<sub>M</sub>, that determine the loop gain of this circuit.
