PC.5. Gain-Measurement Frequency Response

Procedure Circuit C3 has the input signal applied through the coupling capacitor. Chan0_out V(CCV) provides the input and output circuit bias. The base signal with dc removed is measured again with Chan2_in. Reconnect the circuit according to Circuit C3. Connect the top of RB to Chan2_out and the bottom of Rs to Chan2_out. Open SetVCEC3.vi and run to determine circuit bias IC and VCC. Note that if VCC > 10 with VCE < 2 V, a smaller value of RC or larger value of RB is required; that is, there is not a valid solution. (If VCE ≈ 2 V for VCC = 10 V, this is satisfactory.) This situation could occur if ...
