PC.4. Amplifier Gain versus Bias Current

Procedure Gain.vi is the main VI that obtains the voltage gain as a function of collector bias current. Open Gain.vi and verify that VBB(init) is set to your value for IC=0.1 mA and VBB/Vs=5. VCC(init) will be forced to 1 V in the execution of Gain.vi. Keep subVI GainSub.vi open to help observe the measurement in progress and to obtain Front Panel information for the maximum current. Verify that the correct data are defaulted in the Front Panel of GainSub.vi. The resistors values are not reset in the top VI. Open 5COLDATA.vi.
