EquipmentTektronix TDS 1002 Digital Storage Oscilloscope BK Precision 4017A 10MHz Sweep/Function Generator BNC Cable SetupPlug both the oscilloscope and the function generator into a 120V AC wall outlet and connect the BNC cable to the output of the function generator and the CH1 lead on the oscilloscope. Turn on both the generator and oscilloscope. Waveform MeasurmentsWave 1Set the generator to a sine wave at 200Hz. Measure the peak-peak voltage:7.52V --measured by grid 7.52V --measured by cursors 7.52V --measured by oscilloscope
Wave 2Set the generator to a sine wave at 75Hz. Adjust the output level slightly. Measure the peak to peak voltage:9.90V --measured by grid 9.84V --measured by cursors 9.84V --measured by oscilloscope
Wave 3Set the generator to a sine wave at about 7kHz. Adjust the output to a high level. Set the oscilloscope to acquire an average of 64 samples to remove the fluctuations in the wave towards the peaks. Measure the peak to peak voltage:19.52V --measured by grid 19.56V --measured by cursors 19.5V --measured by oscilloscope.
Wave 4Set the generator to a sine wave at 500Hz. Adjust the output to a low level.3.72V --measured by grid 3.76V --measured by cursors 3.76V --measured by oscilloscope.
Wave 5Leave the generator at 500Hz. Adjust the output to an high level. Set the generator to a large positive DC offset. Note that with sufficiently high DC offset the waveform seems to be displayed improperly. Specifically, it appears that the oscilloscope does not measure above 13V. As the DC offset is lowered, the waveform returns to a sinusoidal wave.TriggeringAC CouplingAcknowledgmentsT. Mahony's Oscilloscope Lab Book for page format LinksPhysics307L
