Run 1: The circuit diagram is given in the manual. First start with the connection as given in the diagram. R1= 47 k ohm,R2= 4.7 k ohm,Rc= 3.3 k ohm and Re= 330 ohm.In the first run we just have to perform DC analysis. So it is asked to measure Vre, Vrc, Vce and Ic. In order to find this we need to set Vcc to 15 Volts. Use the multimeter.Set voltage mode (DC). Switch on the multimeter and touch the black probe at the ground and the red one to the Vcc on the bread board. Adjust the black button (on the bread board just near the Vcc) to get the multimeter reading 15 Volts. To find Vre and touch the both ends of the resistor Re with the black probe and red probe. Similarly to find Vrc touch the black and red probes of the multimeter at the ends of resistor Rc. We can find Vce also by the same method. To measure Ic disconnect Rc from the collector terminal and connect that end to any other region on the bread board. Now put one probe( black or red) on the collector and the other on that end of the resistor which you disconnected. That will give us the value of Ic.
Run 2: Make connections as shown in the diagram. Capacitor value is 10 micro farad and Rs = 1.2 k ohm. Now we are performing the AC analysis. We need to make use of the frequency generator. As it is said we need 1k hertz frequency signal we generate using the Frequency generator. Turn the knob of the frequency generator to 1kHz and then connect the red and black probes connected to the frequency generator to one end of Rs and Ground respectively. Now we use the CRO to generate 10mV. Use channel 1 of the CRO and connect the red and black probes to the other end of the resistor and ground respectively. Now switch on the CRO and the bread board and u will be able to see a sine wave on the CRO. Adjust the Volt/divisions of channel1 to say 0.5mV/div and see that the distance between the crest and trough is 2 divisions such that the net voltage generated is 2 divisions * 0.5mV/div = 1 mV. You can keep the volt/div to 1mV also but the distance between the crest and trough must be 1 division only. So this is the way how you generate AC signal to 1 mV. Remember: CRO must be in AC state. To find Vi, use channel2 and ground the black pobe while the red one must be connected to the base. Adjust the volt/div of channel 2 to get a wave on the CRO. After you get the wave multiply the volt/div with the divisions between the crest and trough. We get the value of Vi. To find Vo we use the same principle as we did for finding Vi but here we connect the red probe of the CRO channel 2 to the collector. We adjust the volt/div to get a wave. After you get the wave multiply the volt/div with the divisions between the crest and trough. We get the value of Vo.
Remember: We will not do anything to channel1 to find Vi and Vo, we just make changes for channel2.
