PC221 Analog Electronics I

Lab Test II: Basic AC circuit analysis

Objectives

1. To test the analysis of simple AC circuits.
2. To test the use of the function generator.
3. To test measurement of simple AC circuits.
4. To test the use of SPICE circuit simulation including transient analysis.
5. To compare results of analysis, measurement, and simulation.

Equipment

• digital multimeter, bench power, function generator, oscilloscope
• various resistors
  

Procedure

1. Measure the component values and DC voltage(s) with a digital multimeter, and fill them in Table 1.
   
   
2. Measure any AC supply voltage(s) with an oscilloscope, (amplitude and offset), and fill them in Table 1.

   V1 (amplitude)
   V1 (offset)
   V2 (amplitude)
   V2 (offset)

   
   
   
3. Build the circuit and measure the appropriate voltages with an oscilloscope and with a digital multimeter, being sure to use appropriate settings for each.
   
   
4. Sketch one of the resistor voltages from the oscilloscope, including horizontal and vertical scales.
   
   
5. Perform a SPICE analysis of the circuit, using whatever type(s) of analysis you need.
   
   Be sure to use the component values and supply voltage(s) from Table 1.
   
   For the voltage you sketched, print the corresponding trace from your SPICE analysis. State what analysis command(s) you used, including the parameters you used.
   Use similar scales for the sketch and your simulation trace so the waves are easy to compare.
   
   
6. Analyze the circuit given using Kirchhoff's laws to determine expected voltages and currents.
   
   Be sure to use the component values and supply voltage(s) from Table 1.
   
   
7. Fill in the following tables. Add more rows if needed.
