Lab 1

Basic Electrical Measurements

1. Obtain the parts for the circuit below. Do not construct the circuit.

2. Measure the resistance of each resistor using the DMM in the Tektronix console.

3. Calculate the current through and the voltage across each resistor in the circuit. Use the measured values of resistance in your calculations.

4. Set up the circuit, and use the Tektronix console DMM to measure the voltage across and the current through each resistor. Record the accuracy of measurement (0.1% of full scale) for each reading.

5. Construct a table to compare your measured values to your calculated values. Do your measurements agree with your calculated values, within the accuracy of the measuring equipment?

6. Adjust the function generator in the Tektronix console to output a 1 kHz sinewave with a magnitude of 1.5 V peak. Display your waveform on the oscilloscope and sketch at least 2 complete cycles of the signal. Label each axis of your sketch with suitable units and calibration points.

7. Adjust the function generator to output a 50 kHz triangular waveform with a magnitude of 1000 mV peak to peak. Display your waveform on the oscilloscope and sketch at least 2 complete cycles of the signal. Label each axis of your sketch with suitable units and calibration points.

8. What is the maximum output frequency of this generator?

Your lab report is due at the end of the lab period. Please use the green engineering paper for your report.

SYLLABUS ADDENDUM

EET2222

Fall 2004

A lab report is required for each lab period and will be due at the end of the period. Lab reports will be informal reports prepared on green engineering paper. No purpose, equipment or procedure section will be required. A typical lab report should contain:

a) Schematic diagrams of all circuits set up.

b) All calculations performed during the lab.

c) Measured data and sketches requested.

d) Answers to questions from the lab handout.

e) The signature of each lab partner, date and the bench number where the
experiment was performed at the end of the report.

Major deductions will be made for data or sketches without units, missing calculations or illegible hand writing. Submit individual lab reports at the end of the lab period.
